Mutenye
Species profile
The heartwood is yellowish brown to brown presenting a dark striping or reddish glints. The sapwood is clearly demarcated. The grain is straight or interlocked and the texture is fine.

The blunting effect is fairly high and slicing is reported to be good. Requires power. Some difficulties in planning due to interlocked grain. Nailing is good but pre-boring is necessary. Gluing is correct for interior only. It dries slowly and must be dried carefully.

Mutenye is moderately durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).

Mutenye can be used for several applications such as:
• interior: e.g. panelling, flooring, sliced veneer, stairs, seats, wood-ware, high class furniture, joinery
• exterior: e.g. heavy carpentry, wood frame house

Substitute for Walnut (Juglans regia) for sliced veneers.
