They are a constituent of dry, open bushland of various types, including mopane and secondary gusu woodlands.[2] They are regularly present on termite mounds,[1][2] the fringes of pans, marshes and dambos, or on river banks (in northern Kenya).[4] They occur in flat or rocky terrain, and thrive on sandy or silty substrates.[4]

Description

Habit

It is a much-branched, coppicing shrub with drooping[2] or rising branches. They grow to between 5 and 12 metres tall.[4]

Leaves

The simple, elliptic or obovate leaves are said to be shaped like mouse ears, hence the name Mouse-eared combretum. The leaves are glabrous above and velvety below, and are carried on short lateral twigs.[1] They usually have 3 to 4 pairs of lateral nerves.[2]

Flowers

The plants produce spikes with creamy white to yellowish flowers in the austral spring time, frequently before the foliage appears.

Fruit

The rufous brown, four-winged samaras average about 2 cm in diameter.[1]

Uses

Dried leaves are used for tea, the gum is eaten, the wood is harvested for fuel, and the roots are used in traditional medicine.[3]
