Strychnos spinosa, the Natal orange,[1] is a tree indigenous to tropical and subtropical Africa. It produces, sweet-sour, yellow fruits, containing numerous hard brown seeds. Greenish-white flowers grow in dense heads at the ends of branches (Sep-Feb/Spring - summer). The fruits tend to appear only after good rains. It is related to the deadly Strychnos nux-vomica, which contains strychnine. The smooth, hard fruit are large and green, ripen to yellow colour. Inside the fruit are tightly packed seeds, which may be toxic, surrounded by a fleshy, brown, edible covering. Animals such as baboon, monkeys, bushpig, nyala and eland eat the fruit. The leaves are a popular food source for browsers such as duiker, kudu, impala, steenbok, nyala and elephant.

Distribution[]

This tree can be found growing singly in well-drained soils. It is found in bushveld, riverine fringes, sand forest and coastal bush from the Eastern Cape to Kwazulu-Natal, northwards to Mozambique, and inland to Swaziland, Zimbabwe, parts of Zambia, northern Botswana, northern Namibia, Angola, Guinea Bissau, to tropical Africa, north west Madagascar, south east Madagascar at Sainte Luce Reserve, north west Ethiopia, and western Tigray at Kafta Sheraro National Park.
