Mimosa aspera N. Sp. Slender shrubs 6-10 feet. high, with Rray 

 bark, with scattered reddish spines flattened s<imew4iat and sometimei? 

 hooked, and about 4 mm. long, the leaf rachis^ often spinose also.. Leaves, 

 with 3-4 pairs of pinnae and about lO'pairs of leafliets, which are oblonc. 

 atxmt 1 cm. long, thick and «hiny, acute, with midrib above . the center 

 and at base with two additional veins below it, and the base oblique. 

 Pods many in a dense head, about 3 cm. long and 8 ram. wide, Jlat^, 

 straight, strongly apiculate but very obtiise, with the surface covered witl^ 

 subulate spines 2 mm. long, which are ^nearly round m cross-section, the 

 nerves on the valves very thii* and rarely spinose 6n the verj' ^dge» the
