Arctostaphylos confertiflora
is a rare species of manzanita known by the common name Santa Rosa Island Manzanita. This shrub is endemic to California, where it grows on the sandstone bluffs of Santa Rosa Island in the Channel Islands. This manzanita is listed as an endangered species by the United States Government. There are a few individuals in two locations on the island, and most of them are threatened by cattle, elk, and deer, which eat them. This is a small, twisting manzanita with blood red to gray bark and glandular bristles on its branches. The leaves are light, dull green, glandular and hairy or bristly. The small flowers are rounded and milky white, less often pale pink, and bunched densely in inflorescences. The fruits are fuzzy drupes around a centimeter in diameter.
