Dalbergia hostilis (Benth.). Yoruba Blackwood. Ogan Oga 
(Yoruba). 
This Dalbergia is fairly common in the Olokemeji Reserve, 
in the Abeokuta province of Nigeria. 
Copaifera sp. True Benin Gum Copal. 
This tree is found near the Uhi, close to the source of the 
Ossiomo River, Benin province. This apparently is rather an 
uncommon tree. The Benin natives do not know how to tap 
the tree for gum, nor how to use the gum. 
Cf. Copaifera. Enyenewu. Enyenewu (Yoruba). 
Found in the Yoruba country. 
Copaifera sp. Boji Hills Copaifera.

Bauhinia rufescens (Kew). 
Found in the Oyo province. 
Bauhinia reticulata (D.C.). Dry-zone Bauhinia. Abafe (Yoruba). 
This Bauhinia grows in dry, open country. It is a small, 
spreading tree bearing white flowers. 
Uses.—The fibrous bark is used for tying, and an infusion 
from the leaves is used in coagulating rubber latex. The 
stem is occasionally used for making house-posts. It is a fire- 
resisting tree and shades the soil. 
Bauhinia Thonningii (Schum.). 
This is a small shrub-like tree of the upper part of the

Entada scandens. Sword Bean, Match-box Bean, Mackay Bean. 
Kakoba, Akhuro (seed) (Benin). 
This large creeper is found in the Benin and Calabar 
provinces of Nigeria. It is not very prevalent. The most re- 
markable features about it are the stoutness of the stem, which 
attains a diameter of nearly 1 foot and the total length of over 
100 feet, and its immense pod, which is often over 3 feet in 
length. The pod is divided into segments, each nearly 2 inches 
square, and each containing one large bean, almost a square 
in shape, 14 inches and nearly ? inch thick. These beans have 
occasionally been used for making match-boxes, for which they
