The wood saws and works fairly easily with both hand and machine tools, with only slight blunting effects on cutting edges; finishing usually gives good results, with a nice polish, but the use of a filler may be needed; it is not liable to splitting in nailing and screwing, with good holding properties; gluing, staining and polishing properties are satisfactory, but the steam bending properties are poor.

Bark is grey, flaking in large, irregular scales and revealing a buff surface, giving a mottled appearance. The leaflets are hairless with a narrowly attenuate apex or drip-tip, and entire margin. Petioles are some 20mm in length and slender, causing the leaflets to droop. The partitions, though, are variable in species and are very short in Entandrophragma speciosa Harms, so that the differences between the two genera become trivial and untenable.
