Elaeagnus latifolia Linn. Oleaster. Wild Olive.
Tropical Asia. The fruit is olive-shaped and larger than an olive. It is eaten in Nepal and the mountains of Hindustan and Siam. The oleaster, or wild olive, has a fruit the size and form of a damson, has a stone in the center and when ripe is of a pale red or cherry color. It is very acrid and though not generally considered an edible fruit in India, yet, when cooked and sweetened with sugar, makes a very agreeable compote. Brandis says the acid, somewhat astringent fruit is eaten. It is abundant on the Neil-gherries, says Wight, and the fruit is edible and also makes a good tart.
