Arctostaphylos obispoensis is a species of manzanita, known by the common names bishop manzanita and serpentine manzanita, endemic to California. [1]
Distribution
The plant is endemic to the southern Santa Lucia Mountains, in the Central Coast region of California. [1] It is found primarily in San Luis Obispo County, and extends into southern Monterey County. [1] [2]
It grows in chaparral and closed-cone pine forest habitats, usually on serpentine soil. It is found at elevations of 60–950 metres (200–3,120 ft). [3]
- Conservation
It is protected within the Cuesta Ridge Botanical Special Interest Area of the Los Padres National Forest, growing in the endemic Sargent cypress (Cupressus sargentii) forest. [4] The species is listed on the California Native Plant Society Inventory of Rare and Endangered Plants as a rare but not currently endangered species. [5]
Description
Arctostaphylos obispoensis is an upright shrub or multi-trunked tree growing to 1–4 metres (3.3–13.1 ft) in height. [1][3]
The small branches and newer leaves are woolly. The mature leaves are glaucous-gray, hairless, and oblong (northern range) to widely lance-shaped (southern range), and up to 4.5 centimeters long. [3]
The inflorescence is a dense cluster of white urn-shaped and downward facing "manzanita" flowers.
The red fruit is a round waxy drupe, 9–14 millimetres (0.35–0.55 in) in diameter. [3]
