British Guiana. Schomburgk, n. 487. 
266. Pithecolobii? v. Enterolobii ? sp.— Falls of the Bs 
sequibo and Rupunoony. Schomburgk, n. 530.— This is 
again a species that, without better specimens, I do not ven- 
ture to refer, with any degree of certainty, to either of the 
above genera. 
267. Pithecolobium érapezifolium.— Mimosa trapecifelts 
Vahl.—Inga trapezifolia, DC. Prod. Yl. p. 441.— British 
Guiana. Schomburgk, n. 984. French Guiana. Martin. 
Pithecolobium is evidently a numerous genus, common 10 
the tropical regions in both the new and the old world, and, - 
. as to the greater number of species, is natural and well cha- 
racterised by the flower as well as the pod; there appear: 
however, to be some exceptions to Martius’ characters. The 
Inga tergemina for instance, which cannot be separated from | 
Pithecolobium, has in all the specimens I have seen a straight - 
pod, and some species, without the pod, cannot be distin- : 
guished from Inga. 
Of Enterolobium of Martius I possess none but flowering 
- specimens, from which, as well as from the figures quoted of 
the pod, I should be inclined to consider it but as a section 
of Pithecolobium. 
268. Inga (Euinga?) pide Humb. rm Nov. Ge. 
et Sp. VI. p. 286 ?— Flowers in nearly sessile lateral heads aS 
in several Pithecolobia, but the foliage is that of the Euing& | 
alate, and answers to Kunth’s description. The pod i$ 
unknown to me.— British Guiana. Schomburgk, n. 595. ` — 
269. I. (Euinga alatz) platycarpa (sp. n.); ramulis peti- 
olis pedunculisque laxe villosulis, petiolo alato, foliolis bijugis
