Ceropegia stapeliiformis is a plant of the genus ceropegia ( ceropegia ) of the subfamily of asclepiadoideae (Asclepiadoideae) in the family of Hundsgiftgewächse (Apocynaceae).
description
Ceropegia stapeliiformis is a succulent shrub with initially erect, but soon creeping and twisting stems that climb the accompanying vegetation. The branches are up to one, more rarely up to 1.5 cm thick and up to a meter long, branching only slightly. They are initially green with a blotchy, darker pattern, but then soon overflow with blotchy red-brown in the sun and turn gray-brown with age. Since the scale-shaped, rounded triangular leaves are only about 3 × 4 mm in size and usually only last a few weeks, the plants appear almost leafless.
The flowers appear individually or usually in groups in short, sometimes up to two cm long stalked inflorescences . The five green sepals are about four mm long, narrow and pointed. The structure formed by the five intergrown petals is about 7 × 2.5 cm, white to greenish-white, with purple spots. At the lower end, an elongated crown basin of about five to seven mm in diameter is formed, which merges continuously into the curved, about two to three cm long and only about three mm thin crown tube. At the top the tube opens like a funnel. The free-standing and splayed or fused and then torn corolla lobes are black-purple and heavily hairy on the inside .
The spindle-shaped, up to 10 cm long follicles are covered with fine warts.
