Santa Barbara milkvetch or locoweed is a variant
of the more common Southern California locoweed (Astragalus
trichopodus var. lonchus). Please refer to that species for
a general description. Var. phoxus has fruit that is compressed
side but is not as bladdery or inflated as var. lonchus, being
approximately 1/8"-3/8" wide as opposed to 1/4"-3/4"
wide for lonchus. Also, in phoxus both the upper
and lower sutures form a distinct ridge, whereas in lonchus the
upper suture is much less convex. Var. phoxus, which was
formerly named A. antiselli, occupies generally dryish inland
slopes and hillsides to about 4000' in chaparral and coastal sage scrub,
blooming from February to June. It extends from Los Angeles to
the Antelope Valley including the West Transverse Range and the west
edge of the Mojave Desert. North of Santa Barbara County, it reaches
the coast. These photos were taken in Kern Co.
