longs to Bentharn's section Vulgares, and subsection Pennatce. 

 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. (Ataxa- 

 cctnthece) 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. 1 



(604.) Same as the foregoing, with larger leaflets ; in 

 flower only. 



(605.) These are fine fruiting specimens, which I refer to 

 A. Rcemeriana, and to them alone the remarks above, as 

 respects the legumes, refer.

 a species uot identified by Mr. Bentham. It was gathered, in flower, near Rin-
