Description:
General:

Shrubs with spreading to decumbent stems often forming large mats or mounds, the branch tips to 2 dm. tall; bark brownish-red, stems puberulent, sometimes glandular.

Leaves:

Leaves oblong to spatulate, the tips acute or abruptly pointed; blades 1.5-3 cm. long, glabrous to puberulent on the margins and mid-rib, the base acute or narrowed abruptly to petioles 2-5 mm. long.

Flowers:

Inflorescence a terminal, few-flowered raceme, each flower subtended by a bract about equal to the pedicel; flowers pink, about 5 mm. long; corolla urn-shaped, with 5 short lobes; stamens 10, the anthers opening by false terminal pores, each with 2 curved, reflexed, horn-like appendages; ovary superior, pubescent.

Fruits:

Fruit a reddish-brown, globose berry, 7-10 mm. in diameter.

Identification Notes:

The fruit is the best feature for distinguishing A. nevadensis from A. uva-ursi. The fruit of A. nevedensis is reddish with splotches of brown or black; that of A. uva-ursi is bright red. Without fruit, look at the leaf color. The leaves of A. nevadensis are bright green on both surfaces; those of A. uva-ursi are dark green on the upper surface and light green on the lower.
