All species formerly considered to belong to the genus Sclerolobium have been moved to Tachigali in line with the treatment by Henk van der Werff in 'A Synopsis of the Genus Tachigali (Leguminosae; Caesalpinioideae) in Northern South America', Annals of the Missouri Botanical Garden Vol. 95, pp 618 - 660, 2008.
Sclerolobium tinctorium Benth.
Tachigali tinctoria is a tree with a spreading crown; it can grow up to 15 metres or more in height. The straight, cylindrical bole can be free of branched for up to 5.5 metres and up to 35cm in diameter[
The tree is harvested from the wild for local use of its wood.

The heartwood is reddish brown; it is demarcated from the pale, pinkish brown sapwood. The texture is medium or
fairly so; the grain moderately straight; there is no characteristic odour or taste; growth rings are present or poorly defined. The wood is very heavy; hard; compact; durable. It is not easy to work; takes a fairly lustrous finish; and holds its place well. The wood is used for house posts and rough carpentry[
The trees of many members of this genus yield a wood suitable for light construction, known in the trade as 'tachi'[
]. We do not have any more specific information for the wood of this species, but a general description of tachi wood is as follows:-
The wood is light brown; it is clearly demarcated from the 3 - 6cm wide band of sapwood. The texture is medium; the grain straight or slightly interlocked. The wood is light to moderately heavy; soft to moderately hard; not very durable in one report[
], durable in another[
]. It seasons at a nornal rate with only a slight risk of distortion, but a high risk of checking; once dry it is poorly stable in service. It is fairly easy to work, but sawn surfaces can be somewhat fuzzy - stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but require pre-boring. The wood is used for purposes such as interior panelling and joinery, furniture components, light carpentry, crates and boxes[
