The difficulty in determining the species, especially of the 
two last sections, is unusually great, the foliage and flowers 
of half-a-dozen or more species are often so similar as to 
render it almost impossible to characterize them without the 
pod, which very seldom accompanies the specimens. The 
characters derived from the proportionate length of the calyx, 
corolla and staminal tube vary, even after the flower is ex- 
panded, according to the period of its development; the in- 
florescence, whether chiefly axillary or terminal, can scarcely 
be judged of from the fragments which our herbaria will hold 
of these large-leaved trees ; the number and size of the leaflets 
depend often on the part of the branch whence the specimen 
is taken; and the hairiness is often very abundant on the 
young leaves and branches, and entirely worn off with time. 
It is, therefore, very probable that many of the species here 
described as new, may hereafter be found to be the same as 
some of those already described which I have not seen. On 
the other hand, it may be observed that the species of Inga 
do not in general appear to be very widely diffused, and that 
most of Willdenow’s, and others which are unknown to me, 
come from Para or Caraccas, from neither of which localities: 
I have any specimens.
