Melodinus monogynus.

Botanical name: 

Melodinus monogynus Roxb. Apocynaceae.

Himalayan region, Malay and China. This plant bears a fruit, says Firminger, as large as a moderate-sized apple, which is said to be eatable and agreeable. Royle says it yields edible fruit. A. Smith says the firm, sweet pulp is eaten by the natives. The berry is red, edible, sweet and somewhat astringent.

Sturtevant's Edible Plants of the World, 1919, was edited by U. P. Hedrick.
