Arctostaphylos rainbowensis
Arctostaphylos rainbowensis is a species of manzanita known by the common name Rainbow manzanita. It is endemic to California, where it is known only from northern San Diego and southern Riverside Counties in the Peninsular Ranges.
It was named for the community of Rainbow, California, near where it is most common in the chaparral of the lower elevation coastal Santa Ana Mountains, and the only manzanita species throughout most of its range.

Description
Arctostaphylos rainbowensis is an erect shrub reaching a bush-like 1 metre (3.3 ft) to a tree-like 4 metres (13 ft) in height. It produces a burl at its base and is coated in reddish brown, smooth bark. The oval leaves are up to 5 centimeters long and 3.5 wide and are hairless and somewhat waxy in texture. The inflorescence is a hanging cluster of white urn-shaped flowers each about 6 to 8 millimeters long. The fruit is about a centimeter wide and ripens to a dark purple-brown.
Extirpation Since the species was first collected its habitat has undergone extensive development, leading to the extirpation of many of its populations.
Identification In some areas, Arctostaphylos rainbowensis overlaps in range with the much more widespread Arctostaphylos glandulosa. The rarer rainbowensis has no hairs of the stems, new growth, and inflorescence, unlike glandulosa.
