928, and 2100 with "pure white" flowers), and at San Luis Potosi 

 (703 Schaffuer) ; with ovate leaves, abruptly cuneate at base and 

 crenately toothed, and fruit large, at Parras (923), and with similar 

 but smaller and sinuately-toothed leaves, and with smaller flowers and 

 fruit, at San Lorenzo de Laguna (925) ; 653 Parry & Palmer. In 

 the multiplicity of forms it seems impossible to distinguish two species, 

 unless it be arbitrarily upon some single character. 



Saracha UMBELLATA, Don. (S. glubrata, Miers.) Near Sau 

 Luis Potosi (702 Schaff'ner) ; G51 Parry & Palmer; also 347 Bour- 

 geau, referred to S. Jaltomata. Roth originally described the species 

 (in 1800) from cultivated plants, without giving their source, but 

 Jacquin in 180-1 refers the species positively to Mexico. 



Capsicum baccatuji, Linn. At Uvalde (931), and at Sutherland 

 Springs, Texas; 1135 Parry & Palmer. 



Cacabus Mexicaxus. Viscidly pubescent throughout, rather 

 stout: leaves broadly ovate and mostly cordate, or the upper ovate- 

 oblong, coarsely sinuate-toothed or nearly entire, obtuse or acute, 2 

 inches long and exceeding the petioles, the upper and secondary ones 

 smaller : flowers solitary ; calyx broadly tubular-campanulate, 6 (be- 

 coming 15) lines long, with acuminate teeth; corolla purplish, 15 

 lines long, broadly funnelform, nearly glabrous without, densely 

 tomentose toward the base within, the limb nearly entire: berry 

 subglobose, G lines in diameter, loosely enclosed in the inflated 10- 

 cariuate calyx. — In the San Miguelito Mountains, vSau Luis Potosi 

 (704 Schaffuer). Near G. prostratus, Bernh. 



Nectouxia FORMOSA, HBK. At Lerios, Coahuila (958) ; 652 

 Parry & Palmer. 



Lycium brachtaxthum, Gray in Hemsl. Bot. Biol. Centr.-Amer. 

 2. 426. At Laredo, on the Rio Grande (963), in the mountains west 

 of Saltillo (860), and at Soledad, Coahuila (867, 868) ; 723 Parry & 

 Palmer. A small loosely branched bush, the angular branches pubes- 

 cent or glabrate, with obovate to oblanceolate or spatulate short- 

 pubescent fascicled leaves (2 to 8 lines long by 1 or 2 wide), and 

 nearly sessile flowers : calyx pubescent, with very short and broad 

 lobes, equalling the broad tube of the cream-white corolla, which is 

 densely woolly within and about 2 lines long: mature fruit 3 lines in 

 diameter. 



Lycium Berlaxdieri, Dun. At Guadalupe, Texas (950), and 

 westward to Laredo (951, 952), at Saltillo (957) and in the mount- 

 ains west of that place (954, 956), and at San Luis Potosi (1059 

 Schaffuer); 654, Qoih, and 656^ Parry & Palmer. Apparently all
