Pomona locoweed is a coarse leafy perennial that grows in procumbent clumps with stout, ascending, glabrous, hollow stems.  The leaves are about 8" long with 25-41 oblong to oblanceolate leaflets, thinly strigose on lower surface.  The flowers are 10-45, spreading or reflexed in a dense raceme.  The petals are greenish-white to cream-colored.  The pods are also in a raceme, ovoid, transparent to papery and bladdery-inflated.  Pomona locoweed grows in shrubby, grassy and weedy areas, fallow fields, and sandy slopes and valleys to 1000', in coastal sage scrub and foothill woodland near the coast and throughout cismontane s. California.  It blooms from March to May.  These pictures were taken in the Santa Rosa Plateau Ecological Preserve.
