About

Buchanania arborescens, commonly known as the little gooseberry tree or sparrow's mango, is a small and slender tree native to seasonal tropical forests of northern Australia, Southeast Asia, and the Solomon Islands.

The leaves are spirally arranged, smooth, leathery, elongated oblong, 5–26 cm long. The flowers are very small cream to yellowish white. The edible fruit are globular, small (1 cm long), reddish to purple-black.

Uses

Aboriginal people eat the fruit raw. The plant is also used as a traditional medicine in Australia and Malaysia. The 1889 book 'The Useful Native Plants of Australia' records that "The unripe fruits of this plant were gathered, and, when boiled, imparted an agreeable acidity to the water, and when thus prepared, tasted tolerably well. When ripe, they become sweet and pulpy, like gooseberries, although their rind is not very thick. This resemblance induced us to call the tree 'the little gooseberry'tree" quoted from Leichhardt: Overland journey to Port Essington, p. 479.
