The kei apple, Dovyalis caffra Warb. (syn. Aberia caffra Harv. & Sond.) is also known as umkokolo in Africa and this is abbreviated to umkolo in the Philippines. The generic name has been rendered Doryalis by many writers but botanists now agree that this form was not the original spelling.
The shrub or small tree, growing to a height of 30 ft (9 m) with a spread of 25 ft (7.5 m), usually has many sharp spines 1 to 3 in (2.5-7.
5 cm) long, though it is often entirely spineless if not trimmed. The leaves, often clustered on short spurs, are oblong-obovate, 1 to 3 in (2.5-7.5 cm) long, glossy and short-petioled. Pale-yellow male and female flowers are usually borne on separate trees. They are small, petalless, and clustered in the leaf axils.Kei Apple fruit plants in Kerala is now available in our farms..
