, a shrub, is most widespread across the Rocky Mountains of Colorado and northern New Mexico, with lesser occurrences in Arizona, southern New Mexico, the Wasatch Range in Utah, and a small area of the Pacific Northwest.
Stems have no spines or prickles, but do have a covering of both stalked and sessile glands, as do the petioles, which are little shorter than the leaf blades. Leaf surfaces are generally hairless and non-glandular.
Flowers are arranged in clusters of between seven and 25, and are attached by glandular pedicels, subtended by lanceolate bracts. Flowers are formed of a pale green or pale pink hypanthium tube, relatively short, topped by five whitish sepals - about twice as long as the tube - and five similarly colored petals. Fruits are glandular, egg-shaped black berries, up to half an inch across; they are produced only infrequently.
