Discussion | Of conservation concern. Brodiaea filifolia is endangered. It grows on clay soils at the edges of vernal pools and flood plains in southern California. It has been extirpated from Los Angeles and San Bernadino counties and is seriously threatened by development, vehicles, and agriculture in Riverside and San Diego counties. It is in cultivation.

Brodiaea minor grows along the low foothills of the Sierra Nevada range. It is very similar to B. purdyi, which may be only a subspecies of it. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
