PiCNTSTEMON TENiTiFOLius, Benth. Ill the Morales Mountains, 

 Sau Luis Potosi (753 Schaffuer) ; 672 Parry & Palmer. 



Pentstemon stenophyllus, Gray. In mountains near San Luis 

 Potosi (754 Schaffner); 671 Parry & Palmer. 



MiMLLUS GLABRATUS, HBK. At Saltillo (977), and at San Lo- 

 renzo de Laguua, Coahuila (978, 979) ; G75 Parry & Palmer. 



Stemodia DURANTiFOLiA, Swartz. Near Morales, San Luis Po- 

 tosi (7 1 4 Schaffner) ; G79 Parry & Palmer. Also a prostrate and 

 rooting variety (?), with sessile flowers, and a broad funnelfurm corolla 

 6 lines long; between the Frio and Nueces Rivers, Texas (1053), 



CoNOBEA MULTIFIDA, Benth. At Sutherland Springs (980). 



Herpestis rotundifolia, Pursh. At Guadalupe, Texas (981). 

 Flowers white. 



Herpestis Monniera, HBK. At San Antonio, Texas (987); 

 677 Parry & Palmer. 



Herpestis ciiam^drioides, HBK. At Guajuco (988), and at 

 Monterey, Nuevo Leon, and near Morales, San Luis Potosi (743 

 Schaffner) ; 674 Parry & Palmer. Mostly with large yellow flowers, 

 often twice the length of the calyx, the outer segments of which are 

 oblonfj-ovate or lanceolate. 988 Palmer has been referred to H. 

 mgrescens, and 674 Parry & Palmer in part to H. radlcata, Benth. 

 The species is a variable one, and easily includes these forms. 



Ilysanthes gratioloides, Raf. Near Morales, San Luis Potosi 

 (121 Schaifner) ; 676 Parry & Palmer. 



LiMOSELLA aquatica, Linn. Near Morales (125 Schaffner). 



Veronica peregrina, Linn. At Monterey, Nuevo Leon, and 

 near Morales (723 Schaff'ner); 678 Parry & Palmer. 



BucHNERA LiTHOSPERMiFOLiA, HBK. (?) Near San Luis Potosi 

 (Schaffner, without number). Apparently a common though some- 

 what variable species in Mexico, and extending into Arizona (2830 

 Lemmon), with leafy stem 1 to 2 feet high, short rough pubescence, 

 ovate to linear-lanceolate bracts, narrow calyx-teeth exceeding the 

 ovate-oblong acute capsule (3 lines long), and corolla 5 or 6 lines 

 long. Bentham identifies the Mexican plant (as represented by 

 100 Hartweg) with this Colombian species, though it does not wholly 

 agree with the description. It is all referred by Ilemsley to B. elon- 

 ffata, Swartz, but that species as represented in the United States and 

 West Indies is very clearly distinguished by its more naked stems, 

 short ovate bracts, short calyx-teeth, and obtuse capsule exceeding 

 the calyx. It is doubtful whether B. elongata occurs at all in 

 Mpxico.
