has limited distribution in southern California, mostly in and around Anza Borrego Desert State Park, along the west edge of the Sonoran Desert. Plants are shrubs, with thorny, woody branches and hairless, light green leaves, ovate to nearly round in outline; less than two times as long as wide.
Flowers are solitary or in groups of two or three, attached by hairless stalks of up to half an inch. The five sepals are light green, shallowly cupped, lined by tooth-like glands, and hairy underneath, while the five petals are a little longer (up to 0.4 inches), obovate, clawed, white to pale pink. Fruits are hairy, egg-shaped berries, green ageing to yellow. Flowers appear at the same time as the leaves, in early spring. The stamens, up to 25, have white filaments and yellow anthers.
