Description

Plants in this genus are generally prostrate to sprawling branching perennials with opposite succulent leaves. Inflorescences are a cyme, and flowers have 5 calyx lobes, 8 to many stamen, and an inferior ovary. Fruits are 2 loculed capsules with basal placentation (see "in plants"), and the fruit is xerochastic (fruit dehisces when dry).[2][3] Their seeds are likely dispersed by ants.[4]

Taxonomy

This genus was first described by Ecklon and Zeyher in 1837.[3][5]
