Orbea conjuncta is a sprawling stem succulent that branches. The procumbent stems are grey-green with scattered blotches and line markings in purple to brown. Longitudinal stem ridges and large teeth or tubercles are spaced upon the stems. These curving, conical tubercles are up to 2 mm long and 1,6 cm apart. The stems become 15 cm long and 8 mm in thick.
Flowers grow solitary or in pairs on reddish brown or brown-green peduncles from the stems. The cream to beige corolla is a wide, shallow cup with five pointed lobes. In the base of this corolla cup, the flower centre is a fleshy crimson ring, the annulus inside which the purple and white outer and inner coronas have variously shaped tiny lobes. The flower has a fetid smell that attracts various sorts of flies, important to the plant as its pollinators.
The fruits, spindle-shaped follicles like antelope horns release a multitude of seeds attached to long white hairs, dispersed on the wind. The plant is a South African endemic, distributed in Limpopo in a small area near the Soutpansberg and the Blouberg. The species is not considered to be threatened in its habitat early in the twenty first century.
An earlier name for this plant was Orbeanthus conjunctus; before that it was known as Stultitia conjuncta (www.llifle.com; www.redlist.sanbi.org).
