5 mm. long. Common throughout southern California and possibly 
in the upper San Joaquin valley, also extending on the islands along 
the coast, to Ensenada Mexico, reaching up into the Lower Temperate

banner and wings, the banner, 4-6 mm. longer than keel and 3-4 mm. 
longer than wings, often purple-tinged, and keel purple-tipped. Flow-

Teeth triangular, about 1-2 mm, long. Pedicels stout about 2 mm. long, 
as long as the triangular bracts. Fruiting peduncles about 2.5 cm, long, 
with 1-4 pods. Leaves when fully developed about 7 em long, broad,
