wide, oblique-lanceolate, falcate, acuminate-mucronate on distal 

 side, nearly glabrous, evidently ciliate, evidently nerved. Pedicel 

 one, 7-13 mm. long, appressed-puberulent with incurved hairs. 

 Sepals lo-ii mm. long, lanceolate, acuminate, puberulent. Petals 

 10 mm. long, the anterior slightly exceeding the lateral. Stamens 

 unequal. Legumes 4 cm. long, 4-4.5 mm. wide, strigose-hirsute,

Type, "Texano-Mexicanum," collected in fruit, Berlandier 

 20j6, in the herbarium of Columbia University at the New York 

 Botanical Garden. 



Apparently differs from Chamaecrista calycioides (DC.) Greene 

 of South America, with which it has been confused, by its fewer 

 leaflets and solitary flowers; doubtless, when C. calycoides is re- 

 collected and fully described, by other characters. 



Besides the type collection, the precise locality of which is 

 unrecorded, seen also from Cameron County, Texas, > May 8» 

 1900, Vernon Bailey 2^1, in the United States National Herbarium.

 by its longer stouter stems, lanceolate stipules, slightly longer
