From information supplied at various times to Kew and to the 
Imperial Institute it appears that the natives of S. Nigeria use five 
distinct plants for the production of red dye:—Pterocarpus Osun, 
. erinaceus, Poir., P. esculentus, Sch. et Thonn., Baphia nitida, 
Afz., and a species of Dracaena. Of these the most important 
appear to be P. Osun and Baphia nitida. The latter gives a scanty 
supply from the place where the trunk has ‘been injured, but with 
the former a more prolonged treatment is apparently necessary—it 
does not give the necessary dye when newly cut, so the natives allow 
it to lie in water in a cool place for 5 to 10 years. 
In the letters accompanying the specimens the name camwood 
has been applied to the products of both trees, but barwood has only 
been used once and that to the product of P. Osun. A detailed 
account of camwood and barwood will shortly be published in “The 
Useful Plants of Nigeria,” K.B., Add, Ser, 13, Part Li. 
The native names for the other dye-producing plants quoted 
above are:—Ope Kankana or Osun Buke (Dracaenasp.), Apepe 
or Ara (P. erinaceus), Gbingbindo (P. eseulentus Je
