Abstract

Until now, the genus Alyssum L. has been represented by a total of 19 taxa in the Flora Croatica Database (FCD). 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 reliable data indicating their presence in Croatia, are: A. hirsutum, A. ovirense, A. repens subsp. transsilvanicum, A. repens subsp. trichostachyum and A. wierzbickii. Following this review, taking into account the latest taxonomic and nomenclatural revisions, the genus Alyssum is represented by eight species and the genus Odontarrhena by three species in Croatian flora.
