Procris crenata C. B. Rob.

crenata: crenate or scalloped (though usually serrate on the leaf margin).

Perennial herb without stinging hairs, often epiphytic or lithophytic, with succulent stems 1-2 cm thick and 40-50 cm long. Leaves towards the end of the stems, opposite with one leaf in a pair reduced in size or absent, thus appearing alternate. Lamina up to 12 cm long, asymmetrically lanceolate-elliptic; margin serrate. Flowers in clusters, axillary or along the stems below the leaves, unisexual with male inflorescences rather rare.

Occasional

Widespread but never common in highlands of tropical Africa and Madagascar.
