numerous short, uncinate prickles. Leaflets 3 to 5 lines long. Flovver swhitc, 

 cording to Mr. Wright, yellowish, according to Dr. Gregg. Legumc two inches 



more in length, with a stipe-like base half an inch long, very smooth. — A w 

 marked species of the section Habbasia Kubicaules.

2 lin. longis), — Hills on tlie Rio Grande, Texas, in great abundance, Jiily ; in 

 flower. — " Plant a foot high/' The leaflets are pilose when young, with longer and 

 looser hairs than those of C. Californicaj soon glabrate, and they are coarsely retic- 

 ulate-veined from a prominent midrib. Thc pinnoe are commonly two pairs, somc- 

 times three. — C, Chamscdrys must be critically comparcd with C. eriophylla of 

 Bentham, who, I perceive, has referred one of Dr. Gregg's Chihuahuan specimens 

 to that species. The leaflets are soon glabrate, and the pinnte frecjuently unijugate.

 with the Nitida Unijugce, near C. brevipes, and is readily distinguished l)y its small 

 stature, few leaflets and flowers, and very hairy leaves. In these respects it is near- 

 er C. eriophylla; but it appears never to have more than one pair of pinna^, and 

 the form and proportion of the flowers are difierent." Benth in litt — Hills at the

 silky hairs, at length glabrate. Flowers apparently pale purple ; the calyx and co-
