L.-BARWOOD. 
{Pteroi j i & jai u Taub.) 
The subject of the red dye-wood or woods, formerly of consider- 
able commercial importance, known commercially as Barwood, is 
one that has occupied the attention of Kew for a considerable 
number of years. The matter has not been finally m nl. <!. 1 . ran- 
apparently more than one species is involved, and possibly also in 
trade circles the name has been at times misapplied. One species, 
PU-rnrarpus Soijauxii, Taub., has, however, been definitely fmin.l 
to be the source of at least part of the Barwood of commerce. 
The following note, in \*hich a resume is given of the knowledge 
attained, is issued with the double object of making that know- 
ledge available and of inviting the communication of the material 
required to i ■ : bat are still obscure. 
Barwood is a product of the West Coast of Africa. According 
to Holtzapffel (Descriptive Catalogue of Woods [1852], p. 73) :— 
" Two kinds of Barwood are imported from Angola and Gaboon 
! v, in split pieces 4 to 5 ft. long, 10 to 12 ins. wide, and 
2 to 3 ins. thick. It is used as a red dye-wood ; the wood ifl rather 
dark red, but the dye rather pale ; it is also used for violin bows, 
ramrods, and turning." 
Owing to the confusion that existed in the literature bearing on 
Barwood and on Camwood -another West African ,|y.-w.^i. 
which has been satisfactorily identified as Baphia H 
(Leguminosae)-an& from the fact that some writers had con- 
sidered Barwood and Camwood to be derived .from the -
