Ornithogalum nurdaniae Y.Bağcı & Savran sp. nov. (Liliaceae), a new species related to O. oligophyllum E.D.Clarke, is
described and illustrated from Uludağ (the Bithynian Olympus), a mountain in NW Anatolia well known for its rich flora and many
local endemics (A2 Bursa province). Diagnostic morphological characters are discussed. Notes are also presented on the ecology,
biogeography, and conservation status of the new species.
