Allium stenodon (= A. baekdusanense), a neglected member among the Korean flora

Abstract

Allium stenodon (Amaryllidaceae) is reported as a returning member of the Korean flora. This species proved to be the only member of the section Sikkimensia among Korean Allium species, and it is easily distinguished by its cylindrical bulbs with fibrous to sometimes subreticulate tunics and blue to purple-blue perianth. Previously recognized A. baekdusanense is treated as an additional synonym of A. stenodon. Photographs and complete descriptions of A. stenodon are provided together with a dichotomous key to the Korean Allium species. In addition A. stenodon is newly recorded in Jilin province in China.
