The Coachella Valley milk-vetch is an erect, slivery winter annual or short-lived perennial that occurs in dunes and sandy areas of the Coachella Valley (Riverside County, California) in the Sonora desert scrub or creosote bush scrub community. Plants flower from February to May, and the fruit produced is a strongly inflated, two-chambered, mottled legume.
Distribution & Occurrence
The Coachella Valley milkvetch occurs in ephemeral, coarse sandy soils, or an eolian sand sea. It occurs along roadsides, in washes, and in sandy pockets between 40-660 m (0- ft) in elevation and may also occur in creosote bush scrub or Sonoran desert scrub.
|Less than 300 individuals were seen in 1992 (USFWS 1992) but population sizes fluctuate significantly depending on seasonal rainfall. Additionally, many historic populations have not been visited recently.|
