C. occulta was present altogether in 51 of the 53 visited sites. Dominantly the regularly irrigated and continuously moist microhabitats (pots, containers, muddy surfaces of geotextile-covered beds etc.) were colonized. During the revision of our recently collected specimens, deposited in JPU and DE herbaria as Cardamine hirsuta L., further individuals proved to identical with this till overlooked species. One of them (27.08.2004., Heves county: Eger [8088.3; 8188.1], coll. by A. Schmotzer, deposited in DE collection) proved to the third documented occurrence in Europe, comparing to the accessed literature data. Eclipta prostrata (L.) L. and Urtica membranacea Poir. are also new aliens for the Hungarian flora. Several introduced individuals of these taxa were found in containers of imported thermophilo...

The original circumscription of M. coccinea was based mostly on the material ofC. tomentosus with misadditions ofC. niger andC. integerrimus s. l. Fruit characters of the latter taxon pro vided the species epithet. The previous intended lectotypes of M. orientalis and M. coccinea are superseded because they were selected from non-original material; the new lectotypes are designated here. The history of Pál Kitaibel's material of Cotoneaster is traced, and its identity is established. Cotoneaster coccineus is the earliest name available for the red-fruited cotoneaster with hairy hypanthia native in Europe and would have to be adopted if M. tomentosa is not conserved against M. orientalis.

However, recent morphological, phylogenetic and karyological studies indicate that this judgement should be revised. In the present paper we typify the name , review its taxonomic history and provide a thorough description, with compilation of previously published data and our new measurements from cultures. Based on our herbarium survey, we outline its Atlantic-Mediterranean distribution area (Spain, France, Italy, Greece, Turkey and Algeria). Habitat preferences are summarized from our field observations, water quality measurements and the label information of the herbarium specimens examined. Intact seeds were found in faecal samples of the Eurasian Coot ( L.) in southern Spain and two of them were germinated, suggesting that has a capacity for long distance dispersal via endozoochory.

We consider the length of labellar papillae as another character separating them; the former has up to 0.5 mm long papillae, whereas in the latter they rarely reach 0.1 mm. Furthermore, two quantitative morphological characters consistently mentioned in the literature are said to show little if any overlap between—and therefore be diagnostic of—the two species: (i) the length of the lateral lobe of the labellum, and (ii) the length of th...

These taxa have so far been included in S. subdanubialis.

By lectotypification this name is applied to a species that is restricted to the Gömör--Torna Karst in southeastern Slovakia and adjacent Hungary. A new description and revised distribution map of S. subdanubialis are presented. Using flow cytometry analysis it is recognised as triploid. Other populations from the Buda and Pilis Mts. and the western Balaton Uplands and Keszthely Mts., previously assigned to S. subdanubialis, turned out to represent two undescribed triploid and presumably apomictic species, endemic to Hungary. The former records of S. subdanubialis from the Vértes Mts. belong mostly to S. pannonica and S. ulmifolia, both endemic to western Hungary. A morphometric analysis of leaf characters demonstrated that the leaf dentation and dimensions are most important in distinguishing between S. subdanubialis, S. danubialis and the two undescribed species, whereas the leaf shape (apex and base) has an important but secondary role in discriminating among these taxa.

This species is supposed to be of hybrid origin between some taxa of S. subgen. Aria Persoon (1806: 38) and S. aucuparia Linnaeus (1753: 477) of S. subgen. Sorbus; such hybrids and stabilized hybridogenous species are currently classified in S. subgen. Soraria Májovský & Bernátová (2001: 21).

It is more than probable that all former Hungarian records of G. acutifolia and G. altissima are erroneous, and actually refer to G. scorzonerifolia, which might have been naturalised in Budapest at the end of the 19th century. Former casual occurrences of G. perfoliata and G. elegans in Hungary are supported by voucher specimens.

To date, our know-ledge is greatly broadened on the flora of the country, so the former Red List is already obsolete. The authors have elaborated a new variant of the Red List of the threatened Hungarian vascular plants between 2004–2007, which intends to provide a more current approximation to the threaten status of the Hungarian vascular flora after the Millennium. The nomenclature of the current Red List follows the comprehensive work of SOÓ (1980). Additional remarks concerning the Hungarian threaten status, taxonomic problems or the most important Hungarian references are also added to the list for each taxon. The new compilation of the Red List (Table 5) takes only indigenous plants or archeophytes species into consideration. Neophytes were normally excluded from the list, except for some long-ago established and definitely declining sp...
