Summary
Found in tropical lowland forests of central and east Africa, Uganda Ironwood or Muhimbi (Cynometra alexandri) is a legume that reaches up to 50 m in height. It is characterized by a wide, flat-topped crown and straight, cylindrical bole that can be branchless for up to 26 m. The bole is usually 20-150 cm in diameter with extensive thin buttresses near the base. It is highly valued for its timber. The heartwood is resistant to termite damage and is used in heavy-duty flooring, construction, marine work and railway sleepers. It is also used for fuel and charcoal-making.

Other Uses
Agroforestry Uses: The tree is used for soil conservation[ 364 ]. Other Uses: The heartwood is a dull reddish-brown with darker markings; it is clearly defined from the grayish sapwood, which turns pale yellow upon exposure. The texture is fine; the grain usually interlocked; without lustrr; sometimes figured. The wood is very heavy and hard, being very resistant to abrasion; the heartwood is rated as durable and highly resistant to termite attack. It dries slowly, with a tendency to surface and end checking, but with little warp. It is fairly difficult to work with hand and machine tools; has a rather severe blunting effect on cutters; turns very well; has moderate steam-bending properties. It is used for purposes such as industrial and heavy-duty flooring, heavy construction including marine work, railroad crossties, mining props, posts etc[ 316 , 364 , 610 ]. The wood is used for fuel and to make charcoal[ 364 ]. 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?.
