is described in the Flora <>f Tropical Africa as having a hard red 
or white wood, and as being widely distributed in Angola. In the 
Catalogue of Welwitsch's Plants, pt. i., p. 277, it is stated that the 
wood of this species is valuable, of a blood-red colour yielding a 
red dye, and of much use for carpenters' work. While, however, 
it appears to be widely employed in Angola as a dye, there is 
nothing to indicate that it is an article of export. 
From personal enquiries recently made in Liverpool, it appears 
that for the past few years Barwood has been practically unsaleable 
in this country, and at the present time may be obtained for 
£2 15s. per ton. 
With regard to Camwood, this is still imported in small 
quantities, that known as ''Grand Bassa," from Liberia, being 
considered the best quality ; the next in importance comes from 
Sherboro, Sierra Leone. Inferior varieties are shipped from 
Gaboon and Old Calabar.
