Strychnos spinosa, the Natal orange,[1] also called Mokotra in Madagascar, is a tree indigenous to tropical and subtropical Africa.

Inside the fruit are tightly packed seeds, which may be toxic, surrounded by a fleshy, brown, edible covering.

The leaves are a popular food source for browsers such as duiker, kudu, impala, steenbok, nyala and elephant.

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 Eswatini, Zimbabwe, parts of Zambia specifically the western part of Zambia since it is sandy and some parts of southern province of Zambia , northern Botswana, northern Namibia, Angola, Guinea Bissau, to tropical Africa, north west Madagascar, south east Madagascar at Sainte Luce Reserve, Southern Kenya on the lower parts of Eastern arc mountains, north west Ethiopia, and western Tigray at Kafta Sheraro National Park.

[citation needed] An iridoid, sarracenin, has been isolated from the root bark of Strychnos spinosa.
