SHRUB: A leafless shrub during drought or frost with smooth reddish-green stems. 1 to 1.5 m tall in Arizona. Two plus meters in frost-free zones southward in Mexico.

RANGE: This shrub is restricted to the nearly frost-free Sonoran Desert areas in far southwestern Arizona and hence into northern Mexico. Several very attractive plants can be found about the campground at Organ Pipe Cactus National Monument.

UNARMED. However, the resinous sap can be an irritant.

FLOWERS: Small, greenish flowers mostly not conspicuous.

FRUIT: A three-valved capsule.

LEAVES: Small leaves are elyptic to heart shape. The leaves are drought deciduous leaving the plant leafless for much of the year.
