Predstavlja jednu od najstarijih kolekcija unutar zbirke Herbarium Croaticum. Vojkovićev herbarij u cijelosti je skeniran i analiziran 2019. godine. Dobiveni popis uspoređen je s popisom kojeg je 1910. g. sastavio i objavio Dragutin Hirc. Analiziran je udio porodica, endema, alohtonih, invazivnih i strogo zaštićenih vrsta u zbirci. Ukupno su zabilježene 342 svojte koje pripadaju unutar 70 porodica. Porodice s najvećim udjelom svojti su Asteraceae (12,9 %), Fabaceae (11,4 %) i Lamiaceae (10,8 %). Zabilježeno je 75 alohtonih svojti od kojih se pet danas smatra invazivnima.

Dianthus sylvestris in the Balkan Peninsula encompasses six subspecies (D. sylvestris subspp. alboroseus, bertisceus, kozjakensis, nodosus, sylvestris and tergestinus), the identification of which is problematic due to a great morphological variability and complex patterns of environmental variation. To explore morphological variation of described subspecies and to investigate how their morphology varies in relation to environmental variations across their geographical distribution, we evaluated 97 populations of D. sylvestris for variability in 25 morphological characters and 20 environmental variables. Number and shape of epicalyx scales, calyx length and petal denticulation captured the greatest extent of morphological variability between populations. Morphometric analyses re...

It has been considered a dubious taxon because its holotype specimen got lost and because of the scant information contained in the protologue. To settle the interpretation of the name and its application to other Western Balkan populations, a neotype was recently designated. Soon after, the lost holotype specimen was accidentally rediscovered. It is in agreement with the (now superfluous) neotype and the most recent circumscription of the species. Here we present the holotype, summarize the previous uncertainty surrounding this taxon and list all its herbarium specimens from Croatia and adjacent regions deposited in the herbaria CNHM, ZA, ZAHO and ZAGR.

Croat., Vol. 19, No. 1, 281–286, 2010, Zagreb. Thladiantha dubia Bunge (Cucurbitaceae) is native to northern China, cultivated in Europe from the second half of the 19th century, then escaped from cultivation and established more or less naturalized populations in Central and SE Europe. In Croatia it was found for the first time in the part of the city of Zagreb called Savica – an area of old backwaters of the Sava River, in nitro-philous, ruderal habitats i. e. antropogenically strongly disturbed stands of floodplain forests of willows and poplars (Salicion albae Soó 1940). Thladiantha dubia Bunge (Cucurbitaceae) vrsta je autohtona u sjevernim dijelovima Kine koja se od druge polovice 19. stolje}a kultivira u Europi. Izlaskom iz kulture uspostavila je manje-vi{e stabilne populacije u srednjoj i jugoisto~noj Europi. U Hrvatskoj je po prvi put prona|ena kod Zagreba, na Savici, podru~ju starih savs...

In this paper a detailed review of this genus in Croatian flora was carried out based on most recent phylogenetic, taxonomic, and nomenclatural studies. Based on the presented results five of the current taxa are not subjected to any nomenclatural change, five require nomenclatural change, nine should be excluded from the Croatian flora while one new taxon should be included. Three taxa should be excluded from the genus Alyssum and included in the resurrected genus Odontarrhena C.A.Mey. ex Ledeb., namely O. muralis, O. tortuosa and O. metajnae. The most substantial change in the genus Alyssum is the exclusion of A. montanum and some related segregates (variety molliusculum and subspecies pagense) from Croatian flora and classification of the attributed populations as A. austrodalmaticum, A. gmelinii, A. pluscanescens and A. repens. The other excluded taxa, without reliabl...
