 Brown. Common in East India and the Archipelago, but apparently not in Africa. 



Of the two Linnsean Rhamni doubtfully referred here by Wight and Arnott, R. (Enoplia is 

 quite correct ; R. Napeca, however, is Zizyphus lucida, Moon ; Thw. Enum. PI. Ceyl. 74. The 

 Linnsean herbarium has very good authentically named specimens of both. — Benth. 



In India a decoction of the bark of the fresh root is said to promote the healing of flesh 

 wounds. The fruit, which has a pleasant acid flavour, is also eaten. According to J. S. Gamble, 

 the wood is used in India for saddle-trees, &c.; weight about 501b. per cubic foot.

 covered underneath, a-s well as the petioles and branches, with a close white or 

 rusty tomentum. Cymes small, compact, and nearly sessile. Ovary 2-celled,
