Hypericum revolutum is a shrub or small tree in the genus Hypericum native to Arabia and Africa. It is evergreen, with leaves opposite, closely spaced and crowded at the ends of branches, c. 20 × 5 mm, green to slightly glaucous, sessile, clasping at the base. Single bright yellow flowers form at the ends of branches, up to 5 cm in diameter, blooming from June to November. Fruit is a reddish-brown capsule, up to 13 × 10 mm.

Hypericum revolutum is characteristic of the Afromontane vegetation, found from 1400 – 2593 meters elevation, and ranging from southwest Arabia through the Afromontane zones of eastern Africa to the Cape; it is also found in the Cameroon Highlands and Bioko, and on Madagascar, the Comoro Islands, and Réunion. It grows along streams in montane grassland and forest fringes.
