Arctostaphylos montana ssp. ravenii

Presidio Manzanita (Arctostaphylos hookeri ssp. ravenii) is a rare native shrub whose only documented location in the wild is in Presidio Park, San Francisco. It is listed by State and federal agencies as an Endangered Species. The U.S. Fish and Wildlife Service says that only one individual of this subspecies remains in the wild and no wild seedlings of this plant have been observed. However, it has been propagated from seeds and cuttings for conservation purposes, and it is sometimes available for garden use. It was formerly classified as Arctostaphylos hookeri ssp. revenii and some sources may still refer to it by that name.
