008 MR. G. BENTHAM ON THE MIMOSE^E 





[Inga 



Sab. Tropical America : spread over the greater part of tropical Brazil, Guiana, and 



Venezuela. 



This differs generally from /. laurina in its more decidedly bordered petiole, exsertcd starainal tube 

 and narrower pod, and from /. marginata in its more coriaceous, less acuminate leaflets ; but intermediate 



specimens occur on botb sides. 



Mimosa didyma, Veil. Fl. Flum. Ic. xi. t. 46, may be a rude representation of some form of this ; but 



the drawing is evidently so inaccurate as to be quite unrecognizable.

Ecuador, and Columbia, to Panama. 



Exceedingly variable, especially as to tbe wings of the petiole, wliich ai-e usually short, cuneate, or 

 obcordate, but are sometimes narrow, and extend almost or quite to the lower pair of leaflets, or even, in 

 some leaves, disappear altogether. /. verrucosa, Presl, Bot. Bern. 66, may belong either to this or to tbe 

 preceding species.

Sab. Tropical America : Brazil, prov. Minas Geraes, Bahia, and Goyaz, and perhaps 

 also North Brazil, but sometimes difficult to distinguish positively from J. coruscans^ of 

 which it may prove to be a variety.
