(Baker f.) Cufod. 
Moringa stenopetala, commonly called the cabbage-tree (along with a number of other species of trees), is a tree in the Moringa family of flowering plants, native to Kenya, and historically to Ethiopia; it is now extinct in the wild in Ethiopia, though still grown there as a crop on the terraces built to conserve water high up the mountains. It is a multi-purpose tree producing edible leaves, seeds used for the purification of water and traditional medicinal products.
The cabbage-tree was planted by African tribes on the complex system of terraces built high up in the mountains of Ethiopia. Here they became domesticated and were bred to improve productivity, the taste of their leaves and the size of their seeds. Since then the improved trees have been introduced into other areas such as the Rift Valley.
The cabbage-tree is a small tree up to 12 m (39 ft), with a much-branched crown and sometimes with multiple trunks. The leaves are bi-pinnate or tri-pinnate, with about five pairs of pinnae and three to nine elliptic or ovate leaflets on each pinna. The fragrant flowers have creamy-pink sepals, white or yellow petals and white stamens. The fruits are long reddish pods with a greyish bloom.
Moringa stenopetala is mostly known for its importance as a nutritious vegetable tree food crop in the terraced fields of Konso, Ethiopia. In this way it is similar to its Indian relative, Moringa oleifera. It is also used for shading of Capsicum and Sorghum crops, as a companion plant; and additionally in folk medicine.
Another use is the clarification and purification of water to make it potable. A powder made by grinding the seeds is found to be more effective at coagulating substances in suspension than the seeds of the closely related horseradish tree (Moringa oleifera) which is used for this purpose in India.
