latum, suberosum. Seminum testa tenuis, cotyledones sicce 
atree. 
2. Cynometra? tetraphylla, Hook. fil.; glaberrima, foliolis bi- 
jugis valde inzquilateris obtusis coriaceis subtus reticulatis jugi 
inferioris ovato-rotundatis, jugi superioribus majoribus ovato- 
oblongis.—Sierra Leone, on the ascent to the Sugar-loaf 
Mountain, Don. 
A single specimen, in a very imperfect state, without flowers 
or fruit, but most probably a Cynometra. The lower pair of 
leaflets are from half an inch to an inch long, the upper ones 
twice as long. In one of the axille are several of the scariose 
bracts, which usually surround the inflorescence in the genus. 
Heudelot’s collection contains a third undescribed species of 
Cynometra; from Senegambia. 
1. Dialium Guineense, Willd.—D. nitidum, Guill. et Perr. FI. 
Seneg. 1. p. 267. t. 58.—St. Thomas and Sierra Leone, Don ; 
from Senegal to Guinea. All the flowers we have opened 
have one petal, as observed by Bennett in his valuable notes 
on the genus, Pl. Jav. Rar. p. 136 et seq. 
2. Dialium discolor, Hook. fil.—Codarium discolor, DC. Prod. 
9. p. 520.—On the Quorra, Vogel, Ansell. 
Besides the differences in foliage mentioned by De Candolle, 
the panicle is looser, with fewer flowers than in D. Guineense, 
the ultimate cymes more compact, the flowers rather smaller, 
containing two petals instead of one, and the anthers are nearly 
sessile, 
The Senegambian collections contain also two species of 
Detarium: D. Senegalense, Gmel., and D. microcarpon, Guill. 
€t Perr., and an undescribed species of the American genus, 
Crudya. 
l. Parkia Africana, Br. App. Oudn. p. 234.—Sierra Leone, 
Don, and apparently frequent along the coast.
