Western Texas. common 



Also Monterey, N. Leon, Berland 



It 



allied to C. apiculata, Mart ^ Galeotti ; but it is more silky-tomentose, larger in all 

 its parts, with broader and caducous stipules, more numerous leaflcts ; tlie mature 

 pods glabrate.

 Pedro River. — Stems 8 to 15 inches high, herbaceous nearly or quitc to the base, 

 from a very thick ligneous root.

 perpendiculari lignosa, strigulosa; foliolis unijugis linearibus lanceolatisve cuspi-

 and on the Rio Grande in Southern Texas. Also in the coUection of 1851, with 

 ripe fruit. — This singular dwarf species, with a pod like that of a Crotalaria (in-

 Fremont on the Gila, where it Is said to be abundant in an arid region. The flowers are rather smaller 

 than in C. Texanum. The legumes two inches long, four or five lines wide, perfectly glabrous, as is 

 the ovary, tardily dehiscent, the ventral suture narrowly, but distinctly and acutely margined. 



I have the following new Cassias from Northern Mexico :
