Hypericum revolutum, the curry-bush, is a shrub or small tree (SA Tree List No. 484). The distribution area is the north-east of South Africa, also Swaziland, Zimbabwe and more widely in tropical Africa. It grows to 3 m in height. The habitat is open grassland and forest margins at high altitude. The plant is often a forest pioneer. The leaves are small, narrow and elliptic with no petiole. Leaf colour is usually bright green or yellowish green, sometimes bluish green. The margins are entire and the tips sharply pointed. The flowers are bright yellow, 5 cm in diameter. There is a mass of thin yellow stamens around the maroon style on a green ovary. The fruit is a brown capsule. The curry-bush name comes from the smell of curry exuded by the bush (Coates Palgrave, 2002).
