Arctostaphylos hookeri is a species of manzanita known by the common name Hooker's manzanita.
Description[]
Arctostaphylos hookeri is a low shrub which is variable in appearance and has several subspecies. These are generally mat-forming plants or low bushes with small green leaves, dense inflorescences of white to pink flowers, and shiny egg-shaped or round red drupes.
Distribution[]
The Arctostaphylos hookeri shrub is endemic to California where its native range extends from the coastal San Francisco Bay Area to the Central Coast.
Subspecies[]
- There are several subspecies including:
- A. h. franciscana - Franciscan manzanita - It was named by Alice Eastwood and is native to the city of San Francisco.[1] It was thought to be extinct in the wild until one specimen was discovered in 2009.[2][3] Less than a month later, Caltrans transplanted this specimen to make way for the Doyle Drive Replacement Project.[4] The U.S. Fish and Wildlife Service designated the Franciscan manzanita as an endangered species on October 5, 2012.[5][6] The National Park Service and Golden Gate National Parks Conservancy are attempting to cross-pollinate the preserved specimen in order to reintroduce the subspecies in the wild.[7]
- A. h. hearstiorum - Hearst's manzanita - native to San Luis Obispo County
- A. h. hookeri - grows in the Santa Cruz Mountains and nearby
- A. h. montana - Mt. Tamalpais manzanita - native to Mount Tamalpais
- A. h. ravenii - Presidio manzanita - one single plant and a few clones exist at the Presidio of San Francisco. Federally listed as an endangered species of the United States.
