Taxon discussion

Onosma kittanae was initially described as endemic to Greece ( Stevanović et al. 2003), until Teppner and Karl (2017) pointed out its similarities to O. pavlovae Petrova & Kit Tan ( O. bulgarica D. Pavlova non Velenovský) from Bulgaria and treated the latter as a synonym of O. kittanae . The species remains a rare, range-restricted Balkan endemic confined to the serpentine substrates of south Bulgaria and NE Greece. In Greece, only two localities were known so far: around the locus classicus in Nomos Evrou ( Stevanović et al. 2003, Teppner and Karl 2017) and between Organi and Chloi Villages of Nomos Rodopis ( Strid 2018). Our third, new locality (Fig. 10 ) forms the westernmost distribution border for the species (Fig. 11 ). According to the [B1ab(ii iii iv) + 2ab(ii iii iv)] criteria, O. kittanae fits the Endangered Category at national level ( IUCN 2012).
