Fruits:

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.
