Piaranthus

Piaranthus is a succulent plant genus in the subfamily Asclepiadoideae, in the family Apocynaceae.

[2][3][4] The plants typically form flat, spreading mats of multiple offsetting stems.

The flowers are small, fleshy, and bear five independent petals in a star shape.

They appear in clusters, each flower up-turned, on a tiny inflorescence that sprouts from the tip of the stem.

The compact, mat-forming stems are very similar to those of the related genus Duvalia, and the two are often confused when not in flower.
