Diagnosis.— Similar to Nama dichotoma , however, Nama arizonica differs in having corollas with glands on the abaxial surface,while those of N. dichotoma lack such glands. Also, N. arizonica has prevailingly sessile glands, while those of N. dichotoma are prevailingly pedicellate. The stem hairs of N. arizonica are stiff, straight, and spreading ascending while those of N. dichotoma are more randomly oriented.The leaves of N. arizonica tend to be scattered along the stem like those of N. hispida , though they can be basally disposed like those of N. dichotoma .
