Arctostaphylos ohloneana is a rare species of manzanita known by the common name Ohlone manzanita in the Santa Cruz Mountains in California. It is endemic to northwest Santa Cruz County, where it is known only from four populations on Ben Lomond Mountain, just south of Big Basin Redwoods State Park.

It was discovered in the 1980s among other manzanita species on the mountain and it was described to science in 2008.[1] There are an estimated 100 individuals in existence.[2]

Distribution

Arctostaphylos ohloneana occurs in maritime chaparral and oak and pine forest habitat on whitish soils of siliceous shale origin.[1] The plants all occur on land owned by Lockheed Martin.[2]

The light green leaves have oval blades up to 3 centimeters long by 1.5 wide. The inflorescence is a panicle of white or pinkish conical or urn-shaped flowers. The fruit is a spherical reddish-brown drupe 5 to 8 millimeters wide.
