The wood of "Ume" has realized as much as £10 per ton, but the 

 export does not appear to have been continuous ; the small billets 

 for use as a dye-wood are sold in the Central Province of Southern 

 Nigeria at 3d. to 6d. the basket load (Kew Bull. 1908, p. 192). 



A specimen of the dye wood of " Osun Pupa " from Fiditi 

 (Ibadan) in the Kew Museum has a specific gravity 0*7 = 43*75 lbs. 

 per cubic foot. 



The tree may be propagated by seeds, which ripen [in the 

 neighbourhood of Ibadan] early in December (Punch, Herb. Kew). 

 " Ume " is reported as common all over the Central Province, 

 S. Nigeria where it grows chiefly on the lower-lying land, and 

 attains a maximum girth of about 9 ft. (Kew Bull. 1. c. p. 193). 



Pterocarpus Soyauxii, Taub. in Hook. Ic. PI. t. 2369. 



A tree up to 100 ft. high, branchlets terete with the bark longi- 

 tudinally ridged, in a young state, together with the petioles and 

 axes of the inflorescences, rusty tomentellous. Leaves impari- 

 pinnate ; common petiole 2^-6 in. long ; leaflets alternate, 11-13, 

 distinctly stalked, linear-oblong or sometimes almost obovate-oblong, 

 slightly produced and a little emarginate at the apex, minutely 

 mucronulate, obtuse or rounded at the base, If— 2^ in. long, 1-li in. 

 broad, glabrous on both surfaces, slightly shining above ; midrib 

 rusty-tomentellous below in the young leaves, at length nearly 

 glabrous ; lateral nerves subparallel, prominent ; veins slightly 

 prominent. Inflorescence a pyramidal panicle, 4-8 in. long, 3^-4| 

 in. broad ; branches spreading or slightly spreading, many-flowered ; 

 pedicels slender, J in. long ; bracteoles J in. long, tomentellous. 

 Calyx-tube 2^ lin. long, tubulose-campanulate, shortly dentate, rusty 

 tomentellous. Standard double the length of the calyx, rounded, 

 narrowed to the base into a long claw, shortly dentate. Wings 

 broadly obovate, with a long claw, about double the width of the 

 keel-petals. Ovary lanceolate, stipitate, silky-tomentellous with 

 rust-coloured hairs ; style glabrous ; ovules 4-6. Legume stalked, 

 compressed, oblique-orbicular 2^-3-^ in. in diam. ; wing of the fruit 

 papery, reticulate, slightly rusty tomentellous. 



Readily distinguished from Pterocarpus tinctorius, Welw., by the 

 form and nervation of the leaflets, and by much longer and more 

 slender pedicels of the flowers (I.e.).

Barwood oi Redwood. 



West Tropical Africa. 



Used as a dye by the natives of the Gaboon and other parts of 

 W. Africa. In the Cross River region Barwood is used by the native 

 women to smear their bodies. 



Its chief use in this country is as a red or red brown dye. The 

 colouring matter appears to be the same as that of camwood (BapJiia 

 nitida) but much inferior. The dye is seldom if ever used alone, 

 being chiefly employed to give the requisite red tone to browns and 

 other colours which contain a red in their composition, and as a 

 foundation for indigo (Jarmain, in Journ. Soc. Arts, xxiv. 1876, 

 p. 988). See Camwood for use in preliminary dyeing operations. 



Barwood is imported in billets, of varying size ; originally they 

 averaged 60 or 70 to the ton or upwards of 30 lbs. in weight each, 

 later 100 to 120 to the ton, and finally the average size became 380 to 

 400 or between 5 and 6 lbs. each (Walker, Journ. Soc. Arts, xxiv. 

 1876, p. 591).
