CuscuTA TiNCTORiA, Mart. In tlie Caracol Mountains, Coalmila, 

 on Serjania (918), and in the mountains near San Luis Potosi, on 

 Schhvis Molle (781 Schaffner) ; G31 Parry & Palmer (referred to G. 

 Xalapensis), also on Schinus. The popular name, according to Dr. 

 Schaffner, is " Zacatlas-culi," — evidently the " Zaca-tlascalli " of 

 Karwinski. 



CuscuTA ODONTOLEPis, Engclm. At Guanajuato (Duges). Dr. 

 Eno-elmann recognizes this as referable to C. odontolepis, though with 

 wider and shorter calyx than in the original specimens, the lobes acu- 

 minate and often reflexed, the scales much larger, ovate and deeply 

 fimbriate, and the style shorter, 



SoLANUM TRiQUETRUJi, Cav. At San Antonio, Texas (929), and 

 at Saltillo (930) ; 633^ Parry & Palmer. 



SoLANUM ToRREYi, Gray. At San Antonio (2102), Uvalde (932), 

 and Bluffton, Texas (933). 



SoLANUM NIGRU3I, Linn. In various forms, at Lerios and in the 

 Caracol Mountains, Coahuila, at Monterey, Nuevo Leon (934), and at 

 Guanajuato (Duges) ; 634 Parry & Palmer. Also with somewhat 

 angled and spinulose branches, the S. ■pterocaulon of Dunal, in sandy 

 places near San Luis Potosi (692 Schaffner), and the var. villosum, 

 Mill., in the mountains about San Luis Potosi (691 Schaffner). 



SoLANUM EL^AGNiFOLiuM, Cav. At Laredo, on the Rio Grande 

 (2101), at San Lorenzo de Laguna, Coahuila (935, 936), and at San 

 Luis Potosi (695 Schaffner) ; 636 Parry & Palmer. 



SoLANUM TUBEROSUM, Liun. In the Sierra Madre, south of Sal- 

 tillo (937, 938), and in the mountains near San Luis Potosi (693, 

 694 Schaffner) ; 632, 633 Parry & Palmer. Schaffner gives the 

 popular name " Peyrilla del monte." 



SoLANUM HETERODOXUM, Dun. In the mountains northeast of 

 Monclova (939), and at Parras, Coahuila (940). Also with smaller 

 flowers and light-colored seeds, at San Luis Potosi (696 Schaffner) ; 

 634^- Parry & Palmer. The seeds ordinarily are nearly black. 



SoLANUM ROSTRATUM, Dun. At San Antonio, Texas (941), at 

 Saltillo (942), and at Guanajuato (Duges). A form with somewhat 

 less pubescence occurs near San Luis Potosi (697 Schaffner) ; 635 

 Parry & Palmer, referred to S. cornutum, Lam., of which there are 

 no specimens in Herb. Gray, — unless, as is probable, S. rostratum 

 itself is to be considered only as the more pubescent form of it. 

 Known, according to Duges, as " Mala muger." 



SoLANUM Cervantesii, Lag. At San Luis Potosi (690 Schaff- 

 ner) ; 638 Parry & Palmer.
