PERENNIAL HERB: Mostly herbaceous, but exceptionally large plants may be woody towards base. Most often plants are less than 1 m tall and straggle for support on other nearby shrubs.

RANGE: Fairly common as an understory plant in mesquite bosques and along major washes mostly above 900 m elevation in the Sonoran Desert of Arizona.

FLOWERS: Typical nightshade flowers arranged in small umbels with prominant yellow stamens and white petals. Look for green spots at base of corolla. Most flowering occurs late spring into fall.

FRUIT: Purple berries with a number of kidney-shaped seeds.


LEAVES: Elyptic leaves are irregularly toothed.
