Astragalus oocarpus

Astragalus oocarpus, the San Diego Milk Vetch, is considered a rare plant, endemic to San Diego County. Found in chaparral at the edges of meadows, it is often confused with Astragalus douglasii when not in fruit, since the plants look very similar. San Diego Milk Vetch has very distinctive, short pods however. The genus Astragalus contains the familiar Loco Weed. Harford's Sulfur butterflies use species in the genus Astragalus as host plants.
