Cynometra alexandri, the Uganda ironwood or muhimbi, is a species of legume that occurs in tropical lowland forests of central and east Africa.

[3] In Uganda it is widespread in the lowland forests (below 2,000 metres a.s.l) in the Western Rift Escarpment, where it shows a tendency toward monospecific dominance.

After initial colonising, a mixed forest would contain Uganda ironwood, Alstonia congensis, Trichilia prieuriana, Khaya anthotheca and Celtis mildbraedii.

The durable and dull, reddish brown heartwood is resistant to termite damage or abrasion, while the greyish sapwood is permeable to preservatives.

[2] Due to its physical properties, such as bending strength, inter-node distance, and leaf surface area, the Muhimbi is favoured by chimpanzees for their daily construction of sleeping platforms or "nests".
