Chaenorhinum minus L. ssp. litorale (Bernh. ex Willd.) Hayek
|
This taxon is very controversial and contrastringly treated being considered sometimes as included in a separate genus, Microrhinum litorale (Bernh. ex Willd.) Speta while other authors' vision consider it as only a subspecies of Chaenorhinum minus L. - ssp. litorale (Bernh. ex Willd.) Hayek. A good monograph of the Microrhinum - Chaeorhinum genera can be found here compiled by Speta (1980). The problem of the genus Microrhinum / Chaenorhinum in Romania was treated by T. Szabo (1983) who denies the presence of Chaenorhinum minus and Chaenorhinum minus ssp. litorale in Romania and replace them with other taxa described by Speta (1980) but his study is neglected in the recent works about the Flora of Romania (Ciocarlan 2000, 2008).Photographs taken from outside Romania, in Croatia (Dalmatia) near Dubrovnik, on rocky calcareous massive outcrops above the Adriatic Sea, August 2009. This is the region for which this species was considered as an endemic taxon until it was discovered in the Czech Republic (Mikolas, V. 1997) at Žilina and Trinec. The author considers this Dalmatian saxiphile calciphile species as probably much spread across Central Europe and adapted there as a ruderal and therefore we consider also that it can be found also in Romania in the near future in some patches of ruderal vegetation. The Romanian authors however (Ciocarlan 2000, 2008) considers this species as present in Romania in natural habitats, probably from the calcareous mountains from the Mehedinti county (considered by T. Szabo (1983) as Microrhinum janchenii Speta, a species originally described from Montenegro). dr. Alexandru Badarau, alexandru@transsilvanica.com
