Brodiaea appendiculata
Brodiaea filifolia
This uncommon species is found at low altitudes in the Sierra foothills of central and northern California, usually in stony, red clay soils that become baked very hard during the flowering season. It is rare or extirpated from coast-range foothills.

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.
