Palmer. The flowers are described as " ro=ei " by Dr. Scbaffner. 

 36 Parry & Palmer, referred to V. pubescens, is the same, and 

 736 Coulter ( V. latistipula, Hemsl.) appears to be an undeveloped 

 form of it. 



Viola Hookeriana, HBK. In the San Miguelito Mountains 

 (180 Schaffner) ; 34 Parry & Palmer. 



Viola Barroetana, SchaiFn. In the San Miguelito Mountains 

 (181 Schaffner); 35 Parry & Palmer. 



Viola cucullata, Ait. ? At Saltillo, a single fruiting specimen 

 with broadly deltoid leaves. 



loNiDiuM VERBENACEUM, HBK. ? In the Sierra Madre, Coahuila 

 (55). These specimens accord nearly with the original figure and 

 description, except that the leaves are mostly opposite. It is however 

 described (not figured) as an annual, while this has an evidently 

 perennial slender rootstock. The flowers are purple. 660 Ghies- 

 breght, from San Cristobal, appears to be the same. I. (?) calceolarium, 

 Gingin, as represented in the drawing of MoQino & Sesse, is very 

 similar, but with an apparently annual root. 



loNiDiDM POLYGAL^FOLiuM, Vent. Wilson County, Texas (57). 

 A puberulent form, with the stipules very small or obsolete. More 

 pubescent specimens, with somewhat smaller flowers and well-devel- 

 oped stipules, were collected at Monterey. This species seems to 

 include the original I. lineare of Torrey, and nearly all that has 

 been referred to it. 



Amoreuxia Wrightii, Gray. At Laredo, on the Rio Grande 

 (58), in fine fruit. To this species belongs 37 Parry & Palmer, as 

 well as the specimens collected at Monterey by Eaton & Edwards, 

 and in Sonora by Thurber, all referred by Ilemsley to A. palmatijida, 

 DC, with which A. Schiedeana, Planch., is identified. Aside from 

 the ovate seed of the one and the reniform seed of the latter species, 

 A. Wrightii may be known by the five broader lobes of the leaves, 

 rather abruptly narrowed downward, the lower lobe often incised 

 on the lower margin, while the leaves of the other have seven or 

 nine lobes which are narrowed regularly to the base. 



PoLYGALA LiNDHEiMERi, Gray. In the Sierra Madre, Coahuila 

 (2143). 



PoLTGALA OVALIFOLIA, DC, At Monterey, Nuevo Leon (65) ; 

 43 Parry & Palmer. 



PoLYGALA PUBERULA, Gray. In the mountains west of Saltillo 

 (64). Identical with specimens of Schiede & Deppe, referred to 

 " P. pubescens, Muhl." Also a form with larger flowers at Saltillo
