Stapeliinae is a subtribe of flowering plants within the tribe Ceropegieae of the subfamily Asclepiadoideae of the family Apocynaceae. The subtribe comprises about 35 genera, including both the stem-succulent "stapeliads" and the horticulturally popular genera Brachystelma and Ceropegia.

Pseudolithos horwoodii is a species of succulent plant in the genus Pseudolithos. Native to arid areas of Somalia, it is a small, leafless plant up to 80 millimetres (3.1 in) tall and 45–60 millimetres (1.8–2.4 in) wide. Its growth habit is squat, unbranched, and blob-like, living up to the name of its genus which means "false stone". Its color is green to grayish brown.
