 stipulis setaceo-subulatis petiolo basi adnatis rigidis persis-

1 From the Rio Grande, Texas, as well as from Northern Mexico, we have the sub- 

 joined species, which is said by Mr. Bentham (in Herb. Torr.) to be " a very distinct,

 Chamaesenna. 



Cassia (Chamaesenna) batjhinioides (sp.nov.): humilis, suffraticosa, hirsuto- 

 sericea ; foliolis unijugis rariusve bijugis oblongis vel subovatis utrinque rotundatis 

 inaequilateris sericeo-canescentibus ; glandula interposita ; stipulis setaceis persisten-

 On the Rio Grande, Texas, August (in fruit,) Mr. Charles Wright. Santa Rosa- 

 lia, Northern Mexico, May (in flower only,) Dr. Gregg. Between El Paso and Chi- 

 huahua, August, Dr. Wislizcnus. — The plant of Dr. Wislizenus is 10 inches high, 

 larger in all its parts and less canescent than the other specimens, which are from 

 three to six inches high. The peduncles in the latter are shorter than the leaves. 

 The three upper stamens are rudimentary ; the linear-oblong anthers open only by a 

 terminal pore. Legumes an inch long, slightly curved upwards, very obtuse, and 

 with an incurved apiculate tip.
