Willdenowia 37 – 2007 243 GERALD PAROLLY & ÖZKAN EREN (ed.) Contributions to the flora of Turkey, 2 Abstract Parolly, G. & Eren, Ö. (ed.): Contributions to the flora of Turkey, 2. – Willdenowia 37: 243-271. – ISSN 0511-9618; © 2007 BGBM Berlin-Dahlem. doi:10.3372/wi.37.37114 (available via http://dx.doi.org/) Continuing a series of miscellaneous contributions on the taxonomy, nomenclature, site-ecology and chorology of vascular plants of Turkey, the second instalment deals with 15 taxa of the families Alliaceae, Apiaceae, Asteraceae, Brassicaceae, Colchicaceae, Dipsacaceae, Euphorbiaceae, Lamiaceae, Papaveraceae and Ranunculaceae. Allium antalyense, Cephalaria gazipashensis subsp. pilifera and Teucrium pseudaroanium are described as new to science and illustrated. Allium (sect. Allium) antalyense belongs to the informal Sphaerocephalon group and is closely allied to A. reuterianum. It is an overlooked local endemic of the Western Taurus (Teke Da8i) and grows in the subalpine belt on limestone. Teucrium (sect. Teucrium) pseudaroanium was found in the Demre Çayi valley in the province of Antalya, where it inhabits limestone marble cliffs of the thermo-Mediterranean belt. It forms together with the Greek endemic T. aroanium and the SW Anatolian endemic T. alyssifolium a group of closely related species that are linked by reticulately distributed characters. Characters and ecological requirements of the members of this T. aroanium group are discussed; the taxonomically important trichome types are particularly considered and figured by SEM micrographs. Chamaesyce nutans, R. peltatus s.str. and Zuvanda exacoides are new records for the flora of Turkey. Three taxa are suggested to be sunk in synonymy, viz. Allium vuralii (in A. scabriflorum), Draba terekemensis (in D. imeretica) and Ranunculus kastamonuensis (in R. peltatus). The new combinations Chamaesyce forskalii and Colchicum figlalii are validated. New keys are provided for the genus Chamaesyce and the infraspecific taxa of Camelina hispida. Key words: Allium sect. Allium, Anatolia, angiosperms, chorology, taxonomy, Teucrium sect. Teucrium. Introduction This second instalment continues a series of miscellaneous contributions dealing with the taxonomy, nomenclature, site-ecology and chorology of the vascular plant flora of Turkey. Explanations and criteria for the inclusion of data in this series, specification of citations as well as sequence of taxa have been published in the first instalment (Parolly & Eren 2006). If not otherwise indicated, all specimens cited have been seen by the authors of the contributions. 244 Parolly & Eren: Contributions to the flora of Turkey, 2 The next instalment will be published in the near future; all colleagues are cordially invited to send their contributions to the editors. In the present part of the series, contributions (apart from the editors’) come from Ilker Çinbilgel (Antalya), Prof. Dr Hayri Duman (Ankara), Dr Adnan Erda8 (Aydin), Prof. Dr Mustafa Gökçeo8lu (Antalya), Prof. Dr Harald Kürschner, Birgit Nordt (both Berlin), Burcu Tarikahya (Ankara), Robert Ulrich (Tübingen) and -inasi Yidirimli (Ankara). Abbreviations. – D. = Da8, Da8i (Turkish: mountain); Da. = Da8lari (Turkish: mountains); T. = Tepe, Tepesi (Turkish: hill); Y. = Yayla, Yaylasi (Turkish: summer pasture). – The abbreviations of herbaria follow Holmgren & Holmgren (1998-), with the recent-most addition of AKDU (= Herbarium of the Akdeniz University Antalya). Electronic supplement. – Reference is made in several places to the electronic supplement to this instalment, which is published on the internet at www.bgbm.org/willdenowia/willd37/ parolly+eren.htm Dicotyledoneae Apiaceae Peucedanum longibracteolatum Parolly & Nordt Descendants of the type material of Peucedanum longibracteolatum were brought into cultivation in autumn 2005 in order to get closer insights into the species’ life cycle and the variation of morphology. Ten individuals survived the wet and long-lasting winter season 2005-06. One individual flowered and fruited in late summer/autumn 2006, while the other plants till today remained in the stage of sterile rosettes. The morphology observed fits the protologue in all details, except that the plant attained only a height of 150 cm (reaching 200-250 cm in the wild). Production of a sticky, bitter and aromatic resin with a Daucus-like smell in the lower part of the stem was found both in the cultivated individual and in plants at the type locality. R. Ulrich re-visited the site in late summer 2006 and found most plants strongly browsed to about half a metre, indicating that the parts with larger amounts of bitter resin are scorned by the cattle (Ulrich in litt. 10.2006). The umbels of the single flowering plant in cultivation were frequently visited by wasps (Polistes spp. and Vespula spp.) and some syrphid flies. The fruiting plant died off shortly after a fairly poor fruit-set, suggesting that Peucedanum longibracteolatum may well have a biennial to pauciennial life cycle. Autogamy seems at least partly possible.

Watson This species was described from the Konya province and is hitherto known only from two localities in the Central Taurus, where it was reported to occur on limestone slopes between 1300 and 1450 m (Duman & Watson 1999). The new record documents its radiation into the Lycian Taurus (now its westernmost station of occurrence) and extends the altitudinal distribution into the subalpine belt. For a general description of the plant and a photograph see Duman & Watson (1999).

The electronic supplement provides the first colour pictures of the recently described Centaurea werneri (Wagenitz & al. 2006). The following gathering was made at the type locality. Willdenowia 37 – 2007 245 Turkey: C3 Antalya: Finike – Korkuteli, N Finike, 460 m, senkrechte Kalkfelsen, S-exp., 24.4.2006, Ulrich 6/2 (B, herb. Parolly). R. Ulrich Brassicaceae Camelina hispida var. stiefelhagenii (Bornm.) Yild. Camelina stiefelhagenii Bornm. represents the strange case where an Oriental weed has its type locality in Central Europe. It was described as an alien plant based on a gathering from a dump area near Dresden, E Germany, where “kleinasiatische resp. syrische Getreideabfälle” had been deposited (Bornmüller 1941: 131). Two decades later, Huber-Morath (1962) recorded it from Kirîehir, Turkey. Hedge (in Davis 1965: 493) treated C. stiefelhagenii as an imperfectly known species closely related to C. hispida Boiss., while Med-Checklist (Greuter & al. 1986) cites it as a doubtful synonym of the latter. Yildirimli (1998), when making the formal combination under Camelina hispida Boiss., designated a neotype (also from Kirîehir), because he believed the type of C. stiefelhagenii at B to be destroyed in the 1943 air raids. However, we could trace the holotype (for its illustration see Bornmüller 1941: t. 349), including Bornmüller’s fully documented correspondence with Hans Stiefelhagen, Dresden, and René Maire, Algiers, related to the description of C. stiefelhagenii. Parts of these letters and postcards (for a selection, see the electronic supplement) are excerpted in the protologue, which in combination with Huber-Morath (1962) still makes a good reading today. A re-evaluation of the type material, the references mentioned and the Camelina specimens kept at B largely confirm the taxonomic treatment of Yildirimli (1998). However, the only character he used to distinguish his var. stiefelhagenii from the other varieties of C. hispida – the “papillose” valves – has no taxonomic value and is also found in other Camelina taxa, including the type material of C. grandiflora Boiss. Such a “papillosity” is caused by bulging cells that give immature fruits of herbarium specimens a papillose appearance. This sampling artefact disappears as the fruits matures. The holotype of C. stiefelhagenii displays fully ripe fruits, which in accordance with the protologue are not at all papillose. The neotype depicted by Yildirimli (1998: 2) represents a plant with immature fruits and is, judging from the shape of the siliculae, possibly identical with C. hispida var. grandiflora (Boiss.) Hedge. Huber-Morath’s collection for a long time was the only record of proper var. stiefelhagenii (Huber-Morath 1962) in Turkey; duplicates of this gathering in ANK could not be traced. New records, provided by the second author and identified with the help of the following new key to the infraspecific taxa of Camelina hispida, are given below. 1.

Eren Draba imeretica (Rupr.) Rupr. = D. terekemensis Yild. in Ot 7(2): 2. 2002 [“2000”], syn. nov. While doing comparative literature studies on the Turkish flora, the first and third author came across an engraving in the splendid “Enumeratio plantarum anno 1890 in Caucaso lectarum” (Sommier & Levier 1900: t. 11), depicting the W Transcaucasian (Gorgean) endemic Draba imeretica. It immediately reminded us of the localised NE Anatolian D. terekemensis, which was described only a few years ago (Yildirimli 2002). The illustrations provided in both works (see electronic supplement) as well as the additional descriptions in Schulz (1927: 130) and Tolmachev (1939) confirmed together with the studies on the original material the conspecifity of both taxa. Anatolian herbarium material of D. imeretica (herb. Parolly) is illustrated in the electronic supplement. Draba imeretica belongs to Draba ser. Imereticae Tolm. It is an Euxine chasmophyte of the forest zone and was hitherto only known from a few localities in Georgia, especially in the environs of Kutaissi, where the Rioni river and tributaries step out of the Greater Caucasus (Kharadze & Mtskhvetadze 1979: 155, Schulz 1927). At least three recent localities are reported from Racha-Lechkhumi (referring to region 3 in “Flora of Georgia 5”; David Kikodze in litt., 2.2007). The discovery of D. imeretica in Turkey is less surprising because the Turkish station (A9 Ardahan, Çildir, between Yildirimtepe köyü and ñeytankalesi) is very close to the Georgian border and lies only c. 150 km apart from the next Caucasian occurrences. In Georgia, Draba imeretica descends along the rivers down to c. 1000 m (Schulz 1927: 130) and seems to prefer gorge positions. Radde’s remark (1899: 262) that this plant “ist am unteren Rion schon bei Kutais und am Hippos (Muri) exklusiv an die Steilfelsen der Kalkfelsen gebannt” equally matches the situation in Turkey. This geological restriction certainly narrows its potential area down to a very few, disjunct ranges. Specimens seen. – See Yildirimli (2002). G. Parolly, ñ. Yildirimli & Ö.

Erect, slender annual herb, 3-6 cm (outside Turkey to 18 cm). Stems simple or branched from base with 1-4 erect to ascending branches; ± tuberculate-hairy throughout. Leaves oblanceolate to oblong-lingulate, the lower (10-)15-30(-50) × 3-8(-12) mm, glabrous or faintly to distinctly papillose at least along the lower surface of the mid-vein; margins subentire or remotely bluntly to acutely dentate; radical leaves narrowed into a distinct petiole comprising ¼-½ of the total leaf length, stem leaves variably narrowed below but always sessile with expanded sheathing, often distinctly auriculate, bases. Inflorescence a raceme with 2-9 large flowers, the lower remote. Pedicels 2-6 mm, patent-erect, scabrid, incrassate in fruit. Sepals 10-12 mm, yellowish green, Willdenowia 37 – 2007 247 saccate at base, loosely papillate hairy. Petals 13-18 mm, intensively yellow with darker claws (in Turkey), in adjoining areas also primerose with yellowish claws; the lamina cuneate-oblong to cuneate-obovate, entire, narrowed below to the much longer claw. Inner filaments free. Siliquae narrowly linear, 40-90 × 2-2.5 mm, slightly curved, patent-ascending, glabrous or tuberculate, style terete, obscurely bifid. Seeds (in Turkish material not present) brown, 1.25 mm, minutely areolate. Recent molecular studies (Warwick & al. 2006, 2007) on Hesperideae Prantl emend. O. E. Schulz have confirmed the morphology-based view that Zuvanda (Dvorák) Askerova was correctly segregated from Malcolmia R. Br. (Askerova 1985). The small, largely Irano-Armenian genus Zuvanda comprises three species with a partly unsettled taxonomy (see Townsend 1980), viz. Z. crenulata (DC.) Askerova, Z. exacoides and Z. meyeri (Boiss.) Askerova. Presently only Zuvanda crenulata (as Malcolmia crenulata (DC.) Boiss.) is known from Turkey (Cullen in Davis 1965: 462). A second species, Z. exacoides, can now be added. This taxon, the only Malcolmia in the sense of the “Flora of Turkey” with yellow petals, is a Mesopotamian element with occurrences in Palestine, Lebanon and Syria (Townsend 1980). Its discovery in an adjoining part of Turkey was quite likely. One record substantiated by voucher specimens near Hasankeyf and additional observations in the Batman and Mardin provinces reflect that Z. exacoides is locally fairly abundant on arable fields over limestone (growing together with, e.g., Ceratocephala falcata (L.) Pers. and Corydalis oppositifolia DC. subsp. oppositifolia) and in devastated xerophytic shrubland composed of Amygdalus arabica Oliv., Anagyris foetida L., Cerasus microcarpa (C. A. Mey.) Boiss. subsp. microcarpa, Paliurus spina-christi Mill., Quercus brantii Lindl. and Rosa spp. A wider distribution in the SE edge of Turkey can be assumed for this early flowering species. For detailed descriptions of and keys to Zuvanda exacoides see Townsend (1980: 1030), Rechinger (1964: 314-317) and Zohary (1966: 266), for its full synonymy Askerova (1980: 524), for illustrations Mouterde (1986: t. 60, fig. 9) and the electronic supplement to this instalment.

Parolly) – Fig. 1. A subspecie typica foliis, squamis involucratis et pedunculis patente pilosis (non glabris) differt. Cephalaria gazipashensis H. Sümbül is known to occur in the Western and western Central Taurus (Göktürk 2002) and is especially abundant in the montane elevations of the Isaurian Taurus. This area appears to be a particular diversity centre of the genus (see, e.g., C. ekimiana R. S. Göktürk & H. Sümbül, C. isaurica V. A. Matthews and C. sumbuliana R. S. Göktürk). In the Göksu catchment area some populations of C. gazipashensis are locally more variable than its protologue (Sümbül 1991) and subsequent treatments in the “Flora of Turkey” (Duman in Güner & al. 2000: 148-149) and by Göktürk (2002) suggest. We observed at different localities plants with non-coriaceous, fairly mesomorphic (basal) leaves and a quite dense, soft and pilose indumentum all over. The (0.1-)0.3-0.6 mm long hairs merge along the margin and the mid-vein gradually into much coarser, 1-2 mm long setae with a 248 Parolly & Eren: Contributions to the flora of Turkey, 2 Fig. 1. Cephalaria gazipashensis subsp. pilifera – A: habit; B: lower portion of stem; C: capitulum. – Drawings by H. Lünser after the type collection. Willdenowia 37 – 2007 249 somewhat swollen base. Proper C. gazipashensis has a leaf indumentum of scattered, bulbotrichous hairs confined to the (mid)-vein(s) and margin; otherwise the leaves are glabrous or sparsely pilose between the veins, and coriaceous and reticulate-rugose. The material of the population of Cephalaria gazipashensis that does not fit the present description comes from the slopes of Akda8 below Gökbel Y. The plants have densely pilose involucral bracts and an obvious indumentum on the peduncles below the capitula. The basal leaves are relatively wide (lamina c. 1.5-2.3× as long as wide, petiole as long as or shorter than lamina). We recognise this population as sufficiently distinct to be described at the rank of a subspecies. The other populations growing north of Akda8 match subsp. pilifera in their leaf indumentum but approach subsp. gazipashensis in leaf shape and often in the glabrous surface of the involucral bracts and peduncles. However, in some individuals of these intermediate plants (see below), some scattered hairs can be found on the involucrum and/or the upper part of the stem. The distinguishing characters of the two subspecies of Cephalaria gazipashensis can be summarised as follows: 1. – Leaves coriaceous, reticulate-rugose, glabrous (stem leaves) or sparsely hirsute especially on veins and margin; lamina of basal and lower stem leaves lanceolate, to 40-60 × 15-18 (-25) mm; petiole of most leaves (clearly) longer than lamina; involucral bracts glabrous or with a few and thin, adpressed hairs; peduncle below capitulum completely glabrous . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subsp. gazipashensis Leaves soft-textured to subcoriaceous, ± densely hairy with a clearly heterotrichous indumentum consisting of soft, spreading hairs on both surfaces and longer setae along midvein and margin; lamina of basal and lower stem leaves (narrowly) ovate to broadly lanceolate, to 30-60 × 20-32 mm; petiole as long as or distinctly shorter than lamina; involucral bracts densely spreading-pilose (to adpressed-pilose) by soft hairs; peduncle below capitulum spreading-pilose with a mixture of dense, short hairs and much longer and coarser setae . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subsp. pilifera The type population of Cephalaria gazipashensis subsp. pilifera was recorded in a Quercus cerris-Q. ithaburensis subsp. boissieri oak forest supported by the lower, gentle slope along the ascent to the Gökbel Y. Phlomis samia is locally the dominant plant in the understorey. The Cephalaria was observed at elevations between c. 1050-1400 m, in various exposures and both at fairly sunny and shady places (including the interior of the forest, gaps, road-sides). The geological substrate noted is dolomitised limestone under a thin cover of humus. Additional notes on Cephalaria gazipashensis. – Following the protologue, the corolla size of C. gazipashensis is given erroneously as 10-15 mm in all publications, but is actually no more than 6-7 mm long. The scale of fig. 3.153c in Göktürk (2002) clearly supports this. The plants of subsp. pilifera are only 30-50 cm tall (not 70-100 cm as indicated for C. gazipashensis). The species is more variable than expected and appears to form the core of a complex species group, including C. dirmilensis Hub.-Mor., C. ekimiana, C. lycica Matthews and C. scoparia Contandr. & Quézel. In spite of the recent achievements by Göktürk (2002), a biosystematic study of this group may reduce the number of accepted species; e.g., the enigmatic C. ekimiana falls in most respects within the range of C. gazipashensis and only barely merits specific status.

Eren Euphorbiaceae Chamaesyce J. Gray The generic split of Chamaesyce from Euphorbia L. is recommended by many experts in Euphorbiaceae today and supported by an increasing number of systematic studies; these results find more and more acceptance in country-wide checklists and floras. If constituted as a distinct genus as advocated here for pragmatic reasons, Chamaesyce forms a large and quite natural assemblage of c. 350-400 species (Raju & Rao 1987). The morphological, physiological, stomatal, palynological, caryological and carpological arguments for keeping Chamaesyce generically distinct from Euphorbia are summarised, supplemented by the relevant references, in Benedí (1997: 286) and Wisskirchen (in Wisskirchen & Haeupler 1998: 142). It is especially noteworthy that the Chamaesyce species are mostly C4 plants displaying chlorenchymatous leaf bundles (kranz syndrome), whereas in Euphorbia C3 and CAM metabolism is recorded. In “Flora of Turkey”, Radcliffe-Smith (in Davis 1982: 571-630) and later Gemici (in Güner & al. 2000: 213-214) treated Chamaesyce “classically” as a subgenus of Euphorbia. The record of a new synanthropic Chamaesyce species for the flora of Turkey provides the opportunity to present a nomenclaturally and taxonomically updated key that also incorporates another addition, Euphorbia forskalii J. Gay (Sümbül 1991, Gemici, l.c.). The description of the Turkish material of this species for the “Flora of Turkey” deviates in some characters (e.g., habit, smaller capsules and seeds) from the descriptions given by Boulos (2000), Migahid (1978) and Zohary (1972) and is partly incomplete concerning some taxonomically relevant characters (hair types, seed colour, etc.). The Anatolian specimens were noted to differ from all Turkish species of the (sub)genus in their always erect reddish stems and entire leaves. However, all standard floras throughout the wide range of this taxon (large parts of Africa, the Canary Islands and Asia eastwards to Central Asia and N India) mention a prostrate habit and at least slightly toothed leaves (e.g., Migahid 1978, Zohary 1972), while reddish stems are found in many Chamaesyce species (see Boulos 2000, Haeupler & Muer 2000, Migahid 1978, Pils 2006). E. forskalii was later also recorded in Antalya (Mutlu & Erik 1999) and these prostrate plants have been identified with the help of “Flora Palaestina” (Zohary 1972; Birol Mutlu, pers. comm. 1.2007). With the present key, Sümbül’s plant would be identified as Chamaesyce canescens (but deviating in leaf shape) or more likely, as C. maculata (of which erect forms are known). The characters of E. forskalii given in the key thus consider the descriptions in the references cited above as well as the herbarium material studied at B. The necessary transfer of Euphorbia forskalii to Chamaesyce is proposed below; the leaves clearly show kranz syndrome. Because the “Flora of Turkey” account (Radcliffe-Smith, l.c.) lacks Chamaesyce synonyms, a short local synonymy (adopted from Benedí 1997) is included in the following key: 1.

T. serpentini Contandr. & Quézel). On closer inspection calyx characters and the leaves, especially the indumentum, looked different. More material collected over the next two years, in co-operation with the second author of the present contribution, revealed that an undescribed species was at hand. Trichomes are among the most useful taxonomic characters in Teucrium and were studied both under the light microscope and the SEM (Fig. 4). The sectional classification and the trichome terminology follow Navarro & El Oualidi (2000a-b). For brevity, the abbreviation for the trichome types used by Navarro & El Oualidi (2000b) were used in Table 1 and are quoted below (alternative terminology in brackets). On pedicels, calyces and corollas of the species considered here, only unbranched trichomes of the following types occur: (1) Glandular hairs: A1: short clavate glandular trichomes with 2(-3) cells; A2: long clavate glandular trichomes with 3 (-4) cells; B1: subsessile glandular trichomes with one cell (bladder-like glands, sunken glandular dots, glandular capitate sessile glands or trichomes). (2) Eglandular hairs: F2: large, very thin-walled, 2-5-celled trichomes; F5: elongated and flexuous, thin-walled 3-7(-11)-celled trichomes; H: very long inter-twined trichomes, fibrouslike, sometimes coalescent.

Distribution and site conditions. – Teucrium pseudaroanium is hitherto known from two localities in SW Anatolia that are only c. 6 km in air-line distance and situated in the thermo-Mediterranean belt (90-220 m) of the Demre Çayi valley near Ka=, Antalya. T. pseudaroanium dwells on N- and W-facing, sheer marble cliffs in gorge position, at the type locality together with a very few, but extraordinarily interesting and showy other plants such as Erica sicula subsp. libanotica (C. & W. Barbey) P. F. Stevens, Stachys bombycina Boiss., and, another co-discovery of Robert Ulrich, Polygala peshmenii Eren & al. at its second known station apart from its type locality (Eren & al. 2007). E. sicula subsp. libanotica is a very local taxon that grows bushily on limestone cliffs; in Turkey especially the Kesme Bo8az site is known (McClintock 1991, Stevens in Davis 1978: 97). The site of T. pseudaroanium at the type locality proper is directly above the river in the narrow valley, which widens at the second place to support extensive alluvial fans. Here, Teucrium pseudaroanium covers as the exclusive plant a cliff high above the water and a talus slope with scattered trees, while E. sicula subsp. libanotica is found on neighbouring rocks. Teucrium pseudaroanium, unlike the related T. alyssifolium, is a real chasmophyte that colonises both strongly shady and sunny cliffs. Depending on the irradiation and humidity, it develops different habits: compact, cushion-like forms with short, erect stems in the sun (WNW Kale, Ulrich 6/7) and fairly lax plants with long, trailing to even pending shoots in the shade (type locality). Phenology. – Teucrium pseudaroanium flowers from end of March till mid of May; at the end of May the first fruits can be obtained. Fruit-set is copious and only few nutlets appear to be abortive. Recommended IUCN threat category. – There are several large marble quarries close by the sites of Teucrium pseudaroanium. Particularly one of them appears to threaten the type locality directly, and it can only be hoped that the marble quality of the Teucrium cliffs is not suitable for mining. Extending work to the cliffs would provide an immediate risk of extinction. Hence, we strongly recommend placing T. pseudaroanium in the IUCN category “Critically Endangered (CR)”, because the estimated whole range is less than 10 km2 (criterion B2) and the population is very unequally distributed in two subpopulations (criterion C2; IUCN 2001): more than 500 mature individuals were counted WNW of Kale, while at the type locality the population size of the species is estimated to be lower than 50 individuals. 256 Parolly & Eren: Contributions to the flora of Turkey, 2 Fig. 4. SEM micrographs of the calyx indumentum (left column) and pedicel indumentum (right column) of the species of the Teucrium aroanium group – A-B: T. aroanium with predominantly short clavate glandular A1-trichomes and long clavate glandular A2-trichomes and a few, scattered subsessile glandular B1-trichomes and fibrous-like H-trichomes; C-D: T. pseudaroanium and E-F: T. alyssifolium with predominantly fibrous-like H-trichomes and subsessile glandular B1-trichomes. – Material (critical point dried): T. aroanium (Orphanides, B), T. pseudaroanium (isotype, Ulrich 6/5, B) and T. alyssifolium (Ulrich 5/4, herb. Parolly). Taxonomy. – Characters such as (1) flowers not conspicuously secund and grouped in few-flowered verticillasters or axillary in upper leaves, (2) the campanulate, actinomorphic (not gibbous) calyx with ± equal teeth, (3) the wide, lilac, white or white-blue short-tubed corolla with a spur in the tube (to which we refer in the description as “pouched“), and (4) the fairly large (in the section 3-5 mm long) and hairy nutlets (see Fig. 3) place T. pseudaroanium in T. sect. Teucrium (Ekim in Davis 1982: 56, Navarro & El Oualidi 2000a). We can confirm the observation of Navarro & El Oualidi (2000b: 285) for some other SW Anatolian species of T. sect. Teucrium (see the list at the end of the contribution) that “this is the only section studied with no glandular trichomes in the corolla”. Within its section, the strongest affinities of Teucrium pseudaroanium are with the geographically close T. alyssifolium, endemic to a narrow ophiolite area in SW Anatolia (Ekim in Davis 1982), and T. aroanium Boiss. of the Chelmos, Killini, Taygetos, Koulochera, Parnonas and Chionovouni mountains of the Greek Peloponnese (Baden 1991, Kalpoutzakis & Constantinidis 2006, Tan & Iatroú 2001). The latter species is a chasmophyte of limestone cliffs. Willdenowia 37 – 2007 257 For good illustrations of Teucrium alyssifolium (as T. serpentini) see Contandriopoulos & Quézel (1976: 425) and Pils (2006: 224), for T. aroanium, see Tan & Iatroú 2001: 285). The three species share a number of characters, including (1) the low, suffruticose habit and the large flowers, (2) the adpressed-tomentose indumentum on leaves and stem (consisting mainly of H-trichomes), (3) the exannulate corolla tube, (4) the lower lip bearded by F2-trichomes, (5) the glandular-pubescent lower parts of filaments, and (6) the obovate, reticulate nutlets. Many character combinations of Teucrium pseudaroanium reappear in one of the other two species, giving the idea of three close, reticulately linked species and may also be evidence for reticulate evolution. Table 1 compares the features of the three species, which are treated here informally as T. aroanium group, which may, after more detailed studies, merit subsectional rank. Teucrium alyssifolium matches the new taxon in (1) the leaf shape and leaf size increasing upwards on stem (not decreasing as in T. aroanium), (2) the indumentum type on pedicels and calyx (see Fig 4: a mixture of many subsessile glandular B1-trichomes and long eglandular H-trichomes, not mainly glandular-puberulent by A1 + A2-trichomes as in T. aroanium), (3) the size of the corolla, (4) the yellowish anthers (stamens of T. aroanium are pink to purple in all parts) and (5) the glandular and eglandular indumentum of the nutlets (the upper part of the nutlets of T. aroanium are densely covered by long eglandular trichomes). T. pseudaroanium and T. alyssifolium are easily told apart by the ± concolourous leaves with acute apices, the different shape of the calyx (which is distinctly acrescent in fruit) and the considerably longer and much narrower calyx teeth of T. alyssifolium. Teucrium pseudaroanium resembles in habit most closely T. aroanium, hence the name, looking especially in floral characters (e.g., in the perfectly matching calyx shape) as a smaller and paler coloured version of the latter. The strongly discolourous, distinctly petiolate and mostly obtuse leaves also contribute to this view (in T. alyssifolium the leaf base tapers so gradually into the petiols that the limits towards the lamina are sometimes hard to assess). Besides the quantitative characters and those shared with T. alyssifolium, T. pseudaroanium differs from T. aroanium by its on average longer petioles, inflorescences with more flowers, weakly mucronulate calyx teeth and a filament indumentum confined to the lower third (Table 1). Within the T. aroanium group, T. aroanium has the comparatively broadest leaves. To all appearances, the two limestone cliff plants Teucrium aroanium and T. pseudaroanium are geovicarious species, although the Greek endemic seems not to descend close to the sea-level (400-2000 m, see Kalpoutzakis & Constantinidis 2006: 280, Tan & Iatroú 2001). The biogeographical concept of the S Aegean arc (e.g., Greuter 1971) provides arguments for explaining this distribution pattern. Indeed, there are also a number of disjunctions at species or vicarious species pair level between the Peloponnese, the E Aegean Islands and SW Anatolia with and without a Cardaegaen distributional gap (Greuter 1971, see also Davis 1971 and Parolly & al. 2005). The site conditions of Teucrium alyssifolium deviate in being “non rupicole et qu’il ne sort pas des substrats ophiolitiques” (Contandriopoulos & Quézel 1976). Phytosociologically, T. alyssifolium mainly grows in high montane to subalpine Thuryion capitatae communities (Quézel 1973 sensu Parolly 2004, Astragalo-Brometalia Quézel 1973), often at wind-exposed and rocky places or on serpentine scree (Parolly 2004, Parolly & Tan 2006). In spite of the obviously reticulate distribution pattern of characters we do not consider T. pseudaroanium to be hybridogenous, but we cannot exclude a certain degree of introgression of T. alyssifolium into T. pseudaroanium. Teucrium sect. Teucrium has, after the addition of T. pseudaroanium, c. 30 species world-wide (Navarro & El Oualidi 2000a), eleven of them occur in Turkey (Duman in Güner & al. 2000: 197-198, Ekim in Davis 1982: 53-75). In Turkey, the genus Teucrium comprises now a total of 32 species, including the recently added T. chasmophyticum Rech. fil. (Dönmez 2006) and the long overlooked T. krymense Juz., recorded from Kars (Özhatay & Kültür 2006 and reference included therein). Anatolia, and here especially the southwestern part, is a major speciation centre for Teucrium sect. Teucrium. From the same area (C2 Antalya) and with matching ecological conditions, another local chasmophyte, T. ekimii H. Duman, was described some years ago (Duman 258 Parolly & Eren: Contributions to the flora of Turkey, 2 1998). The other two SW Anatolian endemic species of the section are T. pestalozzae Boiss. and T. sandrasicum O. Schwarz (Ekim, l.c.).

Nordt Papaveraceae Corydalis haussknechtii Lidén That the spring flora of SE Anatolia area is still insufficiently known is underlined by a geophyte that seems according to the new field observations to be closely linked to the “Kurdo-Zagrosian Quercus brantii forest belt” sensu Zohary (1973) in Iran, Iraq and Turkey. There is apparently only one localised record of Corydalis haussknechtii from Turkey, i.e. the type gathering from Detik, Mardin, that dates back to 1867 (Lidén in Güner & al. 2000: 24). In reality, this Corydalis grows in great abundance in the wider Mardin Da. range, sometimes next to Zuvanda exacoides. A Turkish plant of unspecified origin is illustrated by Pils (2006: 264).

Gray by Dönmez (2003) for the identification of a puzzling water crowfoot from Kizilcahamam National Park led to R. kastamonuensis A. Dönmez. This species is hitherto only known from the type gathering from the eponymous province. Our material fits for all but one of the discriminating characters: the weakly lobed lamina of the floating leaves of Tarikahya & Parolly 06-158a does not at all correspond with the strongly trisected (trifoliolate) lamina of R. kastamonuensis. Because the “Flora of Turkey” account (Cook in Davis 1965: 195-197) could also not solve this problem, we expanded the taxa considered for comparison to the whole species inventory of Europe and adjoin- Willdenowia 37 – 2007 259 ing areas by consulting the standard floras of that area and the rich voucher collection of Ranunculus subg. Batrachium housed at B. On this base, our gathering could be identified as the highly polymorphic Ranunculus peltatus s.str., which is not yet recorded for Turkey (Cook l.c., Davis & al. 1988, Güner & al. 2000, Seçmen & Leblebici 1996). R. peltatus is widely accepted to comprise three subspecies, viz. subsp. baudotii (Godr.) C. D. Cook, subsp. fucoides (Freyn) Muñoz Garm. (= R. saniculifolius Viv.) and subsp. peltatus (e.g., Cook 1986, 1993, Dahlgren 2002, Haeupler & Muer 2000, Wisskirchen & Haeupler 1998). A closer literature survey (e.g., Casper & Krausch 1981, Cook 1966, Nebel 1993, and references cited above) and the additional herbarium study brought a nearly complete break-down of the key characters used by Dönmez (2003, largely based on Cook 1964 and Cook in Davis 1965). For example, the strigose nutlet indumentum of R. kastamonuensis can also occur in R. aquatilis L. and R. peltatus s.str. (cf. the perfectly matching figures in Cook 1986 and Haeupler & Muer 2000: 66), while the petal size of R. peltatus subsp. peltatus can (with 3 mm in extreme forms) be as small as indicated for R. kastamonuensis. Moreover, R. peltatus s.l. is known to develop land forms or other dwarf plants with deeply divided leaves exactly matching those of R. kastamonuensis (see Cook 1986: 292, fig. 98, Fischer & al. 2005). Therefore, we consider with some reservation R. kastamonuensis as conspecific within the wide compass of R. peltatus subsp. peltatus. The two gatherings discussed and cited below apparently represent the first records for Ranunculus peltatus subsp. peltatus for Turkey. They belong to a small-flowered form with large and fairly few nutlets and short peduncles and petioles – all characters that are influenced by the environment, for nutlet characters especially by the pollination situation (Cook 1966). In contrast to Ranunculus peltatus subsp. peltatus, subsp. fucoides may not occur in the EuroSiberian (including Xero-Euxine) areas, but is widespread in Mediterranean Turkey. In the neighbouring countries, R. peltatus subsp. peltatus is also known from Greece (Dahlgren 2002) and the Caucasian territories (Krechetovich 1937, as Batrachium carinatum Schur, B. dichotomum Schmalh. and B. triphyllum (Wallr.)

Etymology. – The name refers to the province of Antalya in SW Anatolia, where the new species was first collected. Note. – In July 2004, during the field studies related to the PhD thesis of the first author (Eren 2005), a very distinct, yet uncommon Allium L. was observed on Teke D. in the western Taurus. In “Flora of Turkey” (Kollmann in Davis 1984: 98-221), it keyed out as A. curtum Boiss. & Gaill. or A. reuterianum Boiss. but clearly differed in a number of important features. A comparison of the material with related taxa and checking the Allium accounts in the Floras of the neighbouring countries (Andersson 1991, Kollmann 1986, Meikle 1985, Mouterde 1966, Stearn 1980, Wendelbo 1971, 1985) revealed the novelty of the species from Teke D., bringing the total number of species of Allium sect. Allium known from Turkey to 56 (see also below, under A. scabriflorum). Willdenowia 37 – 2007 261 Fig. 6.

Distribution, site conditions and phenology. – Allium antalyense seems to be an extremely rare, neglected endemic of the Lycian Taurus and is hitherto only known from its type locality on Teke D. in the eastern Beyda8lari. This mountain range is known for its many narrow endemics, including recent discoveries; the new discovery underlines the potential of this area (Davis 1955, 1971, 1965-1985, Davis & al. 1988, Eren & al. 2004, Hartvig & Strid 1987, Parolly & al. 2005). Putatively an E Mediterranean genoelement, Allium antalyense grows in various exposures preferably in dry, gappy limestone swards between 1900 and 2000 m. Subalpine grasslands with different proportions of dwarf-shrubs and thorn-cushions are among the most prominent and abundant formations of the xeric SW Asian high mountain ecosystems (Barbero & al. 1975, Kürschner 1986a, b) and the dominant vegetation of the Beyda8lari.

A. antalyense flowers in July. Recommended IUCN threat category. – We strongly recommend placing Allium antalyense in the IUCN category “Critically Endangered (CR)”, because the estimated whole range is less than 10 km2 (criterion B2) and the population size of the species is estimated to be lower than 50 mature individuals (criterion D; IUCN 2001). The very small number of less than 40 individuals does not secure the unhindered survival of the species for a long time. Seeds of this rare and scattered plant should be collected and stored in a seed bank to safeguard its existence. Relationship. – Allium antalyense fits in Allium sect. Allium that encompasses those species of Allium with well-developed bulb, stem (never basal) leaves, campanulate to cup-shaped (never stellate) flowers, filaments in two distinct whorls, the outer three nearly always simple and the inner three markedly tricuspidate (rarely 5-7 cuspidate), and ovaries with distinct nectariferous pores (Wilde-Duyfjes 1976, Stearn 1981, Mathew 1996). There is no phylogenetic classification below the sectional level available that could give some hints on the relationship of the new species. Within Allium sect. Allium, it clearly belongs to the informal Sphaerocephalon group (Mathew 1996) and seems to be most closely allied to A. reuterianum. Allium antalyense can be distinguished from A. reuterianum on account of its (±) smooth leaf margins (not scabrid), white flowers with green mid-veins (not deep reddish purple), white to yellowish anthers (not purple) and the coarsely papillose indumentum all over the outer surface of the perigon segments, especially in the centre (Fig. 5 and 6). Groups of papillae tend to form crest-like structures (absent in A. reuterianum) along the central part of the mid-vein. In contrast to A. reuterianum, A. antalyense has sharply winged, shiny brown and longer pedicels, larger flowers (longer perigon segments), shorter styles and larger umbels (for figures of these quantitative characters, see Table 2). The combination of characters makes A. antalyense a distinct and easy-to-identify species. For a colour photograph of A. antalyense see the electronic supplement. In the coarsely ornamented segments and the colour of the flowers, Allium antalyense resembles A. artemisietorum Eig & Feinbrun (see Mathew 1996: t. 15A) from Israel, Jordan and Saudi Arabia, which, however, differs clearly by its reticulate fibrous tunics and belongs to another informal group (Scabriflorum group sensu Mathew 1996). Further similar and related species are compared in Table 2. Our taxonomic approach places considerable emphasis on the habit (procumbent-ascending versus erect stems, see Table 2), the ornamentation of the segments, as well as the colour of the flowers. It is noteworthy that Allium antalyense forms an exclusively white-flowered population. The deep reddish purple flowering A. reuterianum with its similar habit is in the Beyda8lari confined to ultramafic sites. Allium sect. Allium provides much difficulties in its taxonomy. In the account for the “Flora of Turkey”, Kollmann (l.c.) recognised 46 species under this section. Since then, ten species were added (Davis & al. 1988, Ekim & al. 1999, Özhatay 1986, Özhatay & Mathew 1995, Özhatay & Tzanoudakis in Güner 2000: 224-232, Tan & Sorger 1987): A. anatolicum N. Özhatay & B. Mathew, A. eldivanense N. Özhatay, A. enginii N. Özhatay & B. Mathew, A. fethiyense N. Özhatay & B. Mathew, A. goekyigitii Ekim & al., A. ilgazense N. Özhatay, A. koyuncui H. Duman & N. Özhatay and A. vuralii Kit Tan) were newly described, while A. erubescens C. Koch was first recorded for Turkey. Finally, A. tuncelianum (Kollman) N. Özhatay & al. was upgraded to species level. In his taxonomic revision of Allium sect. Allium, Mathew (1996) accepted 114 species and several subspecies, all of which mainly occur naturally in Europe and Asia; only A. dregeanum Kunth and A. alibile A. Rich. occur in S Africa or Ethiopia, respectively. Turkey harbours c. 50 % of the species of Allium sect. Allium and has a high species endemism level (> 40 %), thus being a major centre of diversity and evolution in Allium sect. Allium. Further biosystematic and molecular studies will certainly drastically reduce the number of accepted taxa.

Parolly Allium scabriflorum Boiss. = Allium vuralii Kit Tan in Pl. Syst. Evol. 155: 102. 1987, syn. nov. Our attempt to name a puzzling gathering of an Allium sect. Allium from the gypsum slopes facing Tuz Gölü near -ereflikoçhisar (Parolly 06-146), brought us into the thickets of taxonomy of the A. scabriflorum group sensu Mathew (1996). Initially, our plant appeared to be distinct from A. scabriflorum in many respects. What began as an approach to delimit the gypsophytic plant from A. scabriflorum proper, ended in the insight that the highly polymorphic A. scabriflorum deserves an emended description rather than the splitt-off of segregates. Completely unexpected, our study let us sink the halophytic A. vuralii in synonymy. This taxon was said to differ from A. scabriflorum especially on account of the shape and proportion of the inner filaments (see especially Fig. 2E & F in Tan & Sorger 1987; cf. Mathew 1996). During our studies, Allium vuralii became more and more enigmatic. We had followed the convincingly simple idea that two closely allied taxa should not occur sympatrically in the same halophytic habitats. Hence, we expected that the plants from the saline plain of Tuz Gölü basin would all have the filament type of A. vuralii, as it is so clearly depicted in the drawing accompanying the protologue. The opposite was the case: all the many specimens, including the topotypes labelled as A. vuralii, showed uniformely typical A. scabriflorum filaments. We also failed to trace the only existing fragment of the type material (“Kit Tan & Vural 1557a, figure and fragment E”, Tan & Sorger 1987) at E (“probably lost”, pers. comm. Kit Tan 2.2007 and “we do not have any material of Allium vuralii”, D. J. Harris, curator of E, in litt., 30.1.2007). We observed much variation in the filament shape (outlines of basal parts, proportion of median to sterile lateral cusps) and in other characters. Sometimes, there are single flowers in the different collections coming from various substrates that have filaments with median cusps ± equalling the lateral cusps, as in Allium vuralii, and sometimes one of the two lateral cusps can show a somewhat widened lateral base. Should there be a pattern behind this, then it seems to be neither pedological nor spatial, but rather temporal. Stamens deviating from “typical” A. scabriflorum and slightly merging towards A. vuralii (we never saw a filament as figured in the protologue) are more often found in collections from fairly late in the year. Since the type of A. vuralii was gathered in mid-October, we consider it as a rare phenological variant of A. scabriflorum (autumn-flowering Alliums are the least known and it is certainly worth trying to col- 266 Parolly & Eren: Contributions to the flora of Turkey, 2 lect more material late in the season with a particular focus on seasonal dimorphism). The other characters that might be used to distinguish A. vuralii from A. scabriflorum (e.g., anthers creamy-white versus purple, perigon segments acute to subacute versus obtuse) also do not hold and already vary within the populations. Many individuals from saline places combine extremely acute segments with filaments perfectly matching Fig. 2F of A. scabriflorum (Tan & Sorger 1987). The following amendments of the description of Allium scabriflorum (based on Mathew 1996) are largely due to the two collections of the gypsum slopes near -ereflikoçhisar. The lavishly growing, clump-forming individuals of this population have a unique appearance due to their tall size, the high number of the narrow leaves, the up to 50-flowered umbels with deep purple perigons showing no bluish hue, the larger, strongly crested-papillose perigon segments with distinctly fimbriate-papillose margins and the well-exserted, mostly yellowish anthers. However, these characters are, although never re-found in exactly this combination, also represented in other populations, so that we hesitate to describe a gypsophytic, subspecific taxon of A. scabriflorum and prefer to have it included in a widely circumscribed A. scabriflorum. Emended description. – Bulbs ovoid, 0.7-2 cm in diam.; outer tunics in various shades of brown; strongly reticulate-fibrous. Bulblets absent, but replacement bulbs of the same size as the parent bulb often persisting within the same tunic and then plants clump-forming. Stems 10-35(-40) cm, smooth, rather slender (1-2 mm in diam. at base) and wiry. Leaves (1-)2-4(-5), mostly shorter than inflorescence but sometimes equalling or longer than it, filiform-terete, fistulose, shallowly canaliculate, 0.8-2 mm wide, scabrid-papillose or glabrous on the margin; sheathing the lower ¼ to 2/3 of the stem; sheath smooth. Spathe ovate, acuminate or shortly mucronate, whitish, membranous, persistent, (1-)2-3-valved. Umbel fastigiate-hemispherical to hemispherical, 0.72.5(-3) cm in diam., dense, 5-40(-50)-flowered. Pedicels unequal, (2-)3-11 mm long, smooth. Bracteoles mostly present, white, membranous. Perigon campanulate. Perigon segments usually violet-blue or pale bluish-violet, sometimes deep purple, occasionally whitish, normally with a dark green or blackish midvein, 4-5(-6) mm long, ovate-lanceolate to obovate, tapering gradually to an acute, subacute, rounded or even retuse apex, the outer ones papillose on the outer surface and scabrid or conspiciously crested along the keel, sometimes nearly all over and also margins fimbriate-papillose, rarely very faintly verruculose to almost smooth, the inner ones smooth to papillose or crested. Stamens with anthers fully to partially exserted at anthesis; filaments smooth, papillose to slightly scabrid-ciliate at base, the outer ones simple, the inner ones with the anther-bearing cusp about 1/3 as long as the widely expanded undivided basal part and about 1/3 or 2 / 3 as long as the lateral cusps, rarely cusps subequalling; lateral cusps slightly to well-exserted; anthers purple or creamy-white to yellowish before dehiscence.

Varol) Parolly & Eren, comb. nov. ≡ Merendera figlalii Ö. Varol in Belg. J. Bot. 138: 89. 2005. We provide here for all those who prefer, in line with Nordenstam (1998), Persson (1993) and Vinnersten & Reeves (2003), to include Merendera Ramond and Bulbocodium L. in Colchicum L., an alternative taxonomy for this recently described species and add some site-ecological notes. The additional gathering nicely confirms the diagnostic characters of C. figlalii against C. caucasicum (M. Bieb.) Spreng. (= M. trigyna (Adam) Stapf), except for the tunic neck length (given as 4-8 cm). The neck is sometimes only 2-3 cm and is thus within the range of C. caucasicum. The anther colour of C. figlalii was noted in the field to be violet (not black or greenish black when dry). The protologue introduces Colchicum figlalii to inhabit on Sandras D. “serpentine rock clearings” at an altitude of 1900-2100 m, where it forms a very small population (Varol 1995). Fortunately, C. figlalii is, at the right time and right place, a quite abundant appearance in the summit region of that mountain range: On 20-21 June 1999, the first author found it scattered in the damp turf on the top of Altinsivri and in massive stands in steep meltwater runnels and snowbeds below the main summit of Sandras D. (Çiçekbaba T.). In phytosociological respects, C. figlalii is closely associated with the local Trifolio-Polygonetalia Quézel 1973 vegetation (hygrophytic meltwater and doline vegetation, see Parolly 2004) It is able to penetrate through the snow-cover and flowers in thousands of individuals inmidst of the flowing meltwater. On Sandras D., it is certainly the most chionophytic plant of that vegetation type. Turkey: C2 Mu(la: Sandras D. above A8la, ascent from Çirali to Çiçekbaba T. (main summit), 37°04'N, 028°49'E, 1900-2150 m, ophiolite, snowbed meadows and meltwater communities, 21.6.1999, Döring, Parolly 6095 & Tolimir (B, herb. Parolly). G. Parolly & Ö.
