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. The largest number of genera are native to Africa, but a more limited number of genera are widespread in Arabia and Asia. Historically, a similarly circumscribed taxon was treated as a separate tribe, Stapelieae.

Pelargonium insularis is a species of plant in the family Geraniaceae. It is endemic to the Samhah island in the Socotra Archipelago of Yemen. It was discovered in 1999 on the north-facing limestone escarpment on the island. It represents the first record of the genus from the Socotra Archipelago. At the time of its discovery only a single plant was found and an extensive search failed to find more. The cliffs in which it occurs are frequently enveloped in low cloud and provide a relatively moist refugium occupying less than 5 km2, on an otherwise desertic island. Local informants know of the plant and comment that it is found along the cliffs and when fresh, provides incidental grazing for livestock. Its natural habitat is rocky areas. It is threatened by habitat loss.
