344 PUOCEEDINGS OP THE AMERICAN ACADEMY 



short acuminate teeth hardly half the length of the tube ; corolla rose- 

 color, G lines long : pod ascending, coriaceous, oblong-ovate and turgid, 

 abruptly contracted to a very short stipe, 1 -celled, with neither suture 

 intruded or the dorsal slightly impressed, about 8 lines long, straight, 

 subpubescent. — In the Sierra Madre, south of Saltillo (239), and 

 also collected by Dr. Gregg (363) at San Antonio de las Alanganes. 

 It belongs to the group Scytocarpi, and is apparently allied to A. 

 coriaceus, Hemsl. 



NissOLiA WiSLiZENi, Gray. In the San Miguelito and San Rafael 

 Mountains (793 and 794 Schaffner). 



NissoLiA PLATTCALYX. Somewhat tomentose-pubescent : leaflets 



2 or 3 pairs, oblong to oblong-obovate, obtuse or retuse, mucronate, 



3 to 6 lines long : calyx-tube broadly campanulate, 2 to 2^ lines long, 

 the filiform teeth nearly as long ; corolla greenish yellow, 8 lines 

 long, the standard pubescent : ovary glabrous at base, finely pubescent 

 above: fruit glabrous or nearly so, 1-3-jointed, 1 to 1| inches long, 

 the joints rather strongly 3-costate on each side, the upper one with a 

 curved wing 9 to 12 lines long by 5 or 6 lines broad, thickened on the 

 dorsal edge. — In tlie mountains east of Saltillo (248, in part). Under 

 the same number were distributed specimens of another unrecognized 

 species, with the round-elliptical to ovate leaflets less pubescent, as 

 well as the petioles, the calyx-tube only a line long, and the ovary 

 and fruit pubescent and villous with scattered yellow hairs. 



Stylosanthes mucronata, Willd. In the San Miguelito 

 Mountains (800 Schaffner). Agreeing closely with this East Indian 

 species, which differs from S. procumhens, Sw., in its pubescence, and 

 in the form and size of the pod. 



ZoRNiA TETRAPHYLLA, Michx. Wilson County, Texas (245). 



ZoRNiA DiPHYLLA, Pers. At San Luis Potosi (805 Schaffner); 

 196 Parry & Palmer. 



Desmodium viRiDiFLORUM, Beck. In the Caracol Mountains, 

 Coahuila (246). 



Desmodium psilophyllum, Schlecht. In the same locality (2136), 

 a variety with broader leaves (4 to 6 lines wide) and verging towards 

 D. Wrightii, Gray, which is very variable in its foliage, and apparently 

 to be united with the present species. 



Desmodium Palmeri, Hemsl. Near San Luis Potosi (796 Schafi- 

 ner, in part) ; 179 Parry & Palmer, mixed with D. Parryi in the 

 Gray Herbarium set.
