longs to Bentham’s section Vulgares, and subsection Pennate. 
The legume is coriaceo-chartaceous, continuous within, flat, 
linear-oblong or oblong, somewhat falcate, 2: to 4 inches long, 
an inch or less in width, raised on a short stipe. Seeds oval, 
flat, brown. It is said to be a shrub, or small tree, with the 
stem one or two inches thick. ‘There are specimens of it in 
Dr. Gregg’s North, Mexican collection. Another Acacia of 
the latter collection, marked by Mr. Bentham A. (Atara- 
canthee) n. sp., not unlike the above in foliage and fruit, 
but with a different inflorescence, was found by Mr. Wright 
from San Antonio to the Rio Grande. 
(604.) Same as the foregoing, with larger leaflets ; in 
flower only. 
(605.) These are fine fruiting specimens, which I refer to 
A. Remeriana, and to them alone the remarks above, as 
respects the legumes, refer.
