Asphodeline tenuior

Asphodeline tenuior, the thin asphodeline, is a species of plant in the family Asphodelaceae, subfamily Asphodeloideae. It is native to the Caucasus (southern Russia, Georgia, Armenia, Azerbaijan), as well as from eastern Turkey and northwestern Iran. Within Russia, it is known from eastern Krasnodar Krai, Karachay-Cherkessia, Stavropol Krai and western Kabardino-Balkaria. It can be found on stony slopes and scree on limestone and sandstone, from elevations of 500–1,000 m. It is threatened by habitat loss and degradation, due to lime pits, slope terracing and cattle pasturing.
