Syrmatium veatchii, synonyms Lotus dendroideus and Acmispon dendroideus, is a species of legume native to California.[1][2] It is known by the common name island broom.[3] It is endemic to the Channel Islands of California, where it grows on coastal bluffs and cliffs. It is a spreading perennial herb or erect shrub approaching 2 meters in height. It is hairless to hairy and gray-green in color.

When known as Lotus dendroideus or Lotus scoparius, the species was divided into varieties, although these are not recognized by some sources.[1] The rarest, var. traskiae, the San Clemente Island broom or San Clemente Island lotus, is limited to San Clemente Island. It is treated federally as an endangered species.[4][5] In the 1990s the Navy removed goats from San Clemente Island and started a management program to benefit this species. Due to the management efforts for this species, it has increased from just 9 occurrences at the time of listing to over 150 populations consisting of over 10,000 individuals. In 2007 the US Fish & Wildlife Service recommended it be downlisted from endangered to threatened status.[6]
