Lyonothamnus floribundus ssp. asplenifolius
This rare tree with reddish brown peeling bark has compound leaves that are divided into 2-7 leaflets. Each leaflet is further divided into numerous oblique lobes that render a fernlike grace to the entire plant. This species occurs naturally only on Santa Cruz, Santa Rosa, and San Clemente islands off the southern California coast. Unfortunately, the grazing pressures of introduced feral goats and other herbivores present a real threat to Ironwood and many other Channel Island plants.
DISTRIBUTION: Rare and threatened by grazing in canyons, rocky slopes, oak woodland, and chaparral on the Channel Islands; 20-500 m.
