Abstract

Allium tribracteatum and related species present a confusing array in California. Previous attempts at classification have been largely unsuccessful and keys that are available are unworkable. Herbarium and field studies were initiated to ascertain if previously overlooked characteristics could be found that would elucidate relationships within the group. Members of the complex were examined morphologically and cytologically. Based on these investigations four of the seven previously described taxa are considered valid: A. cratericola, A. obtusum, A. tribracteatum, and A. yosemitense. Allium tribracteatum is redefined and A. obtusum is divided into two varieties. Allium obtusum var. conspicuum var. n. is described. A key to the species is presented and relationships within the complex are discussed.
