Kei Apple
Dovyalis caffra
Observed on a farm west of Eldoret, Kenya. April 2013. The fruit will ripen to orange and quickly get the attention of birds.
This large thorny shrub or small tree makes a good barrier fence while at the same time yielding tart, but edible fruit. The leaves are glossy green and oblong in shape. The leaves are alternate on the stem and the thorns arise from the leaf axils. Older growth may have few thorns. Fruits are
about 2½ cm in diameter and yellow when ripe. Until recently this plant
was catagorized into the family Flacourtiaceae.
