Lathyrus sulphureus W.H. Brewer ex A. Gray
USDA Symbol: LASU
USDA Native Status: L48 (N)
Several sprawling or clambering, angular stems bearing pinnately compound leaves and yellowish to orange pea flowers turned to one side in racemes growing from leaf axils.
The unusually broad base and the barely upturned end of the banner produce a stubby flower, hence the common name. Del Norte Pea (L. delnorticus), which grows near the California-Oregon border, has wing-like ridges on the stem.
