Abstract. For the first time are presented chorologieal notes for plant species growing on serpentine
terrains in soulInvestcm Bulgaria. The ehorologv of 7 taxa, three of them Balkan endemics, is discussed -
Psihtrus incurvm (Оо nan) S chiu z et T h ell., Ceraxtium pumilhun Curt., Genista carinalis Grsb.,
Trifoitian scabrum L. subsp. scabnun, Koeteria simonkaii Adam., Moenchia graeca B Mel dr.,
Onohrychis alba (Waldst. et K it) D esv. ssp. calcarea (Wandas) P. W. B all. The chorologieal information
is new for the floristie regions West Frontier Mountains and Struma valley and for the Пота of Vlahina
Mountain as well.

The ultrabasic rocks shelter a specific fiora that differs from other floras by the
processes o f speciation and the presence o f various morphoiypes. The serpentine flora is
characterized by its xeromorphic structure, considerable morphological variations and
dispersed populations (B rooks, 1987; K ruckeberg, 1992).
Purposeful investigations on the serpentine flora in Bulgaria were initiated in 1997
in the Eastern and Central Rhodopes Mountains (P av lova . 2001. 2004; D im itrov.
P a v lo v a ,2002; P av lova et al., 2002, 2003, 2004), However this is still not thoroughly
investigated from taxonomical and ecological points o f view. For example, little is known
