PERENNIAL: After periods of cold weather the leaves and stems change to red. Stems may spread out prostrate up to 30 cm, sometimes with stems ascending.

LEAVES: The leaves are opposite on the stems and the tips are blunt pointed.

RANGE: Upper Sonoran Scrub on rocky or sandy slopes from central Arizona south into Sonora. Also New Mexico and western Texas.

FLOWERS: The small flowers are showy in mass. Minute flowers in an urn-shaped structure bearing red glands and white or pink appendages.

UNARMED: No thorns, but the milky sap can be a skin or eye irritant.

FRUIT: Very small capsules, barely larger than 2 mm, are hairy, three-parted and each contains usually three seeds.
