Astragalus tricarinatus
Also called Triple Rib Milk Vetch, Triple Ribbed Milkvetch
Triplerib milkvetch is a rare, federally endangered perennial herb from the Pea family, found only in one area of southern California's desert edge. It grows as a low clump in desert scrub and rocky ground among Joshua trees, so it needs open, dry, well-drained conditions.
Astragalus tricarinatus is a rare species of milkvetch known by the common name triplerib milkvetch, or triple-ribbed milkvetch.
It is endemic to California, where it can be found in the region where the San Bernardino Mountains meet the Mojave Desert and the Colorado Desert. It grows in desert scrub and expanses of rock litter amongst stands of Joshua trees. The plant is known from only one location and there were twenty individuals remaining there in 1998, when it was federally listed as an endangered species.
