Hypericum denticulatum, HBK. About San Luis Potosi 

 (607 Schaflfuer, in part) ; 72 Parry & Palmer. 



Htpeuicum pauciflorum, HBK. Specimens which agree fairly 

 with the original incomplete description of this species are collected 

 by Dr. Schaffner, together with H. denticulatum and the following 

 species. Parry «& Palmer distributed it also with the next as n. 73, 

 referred by Hemsley to H. fastigiatum, HBK. The whole plant is 

 glaucous, the stem 4-angled, simple, 6 to 15 inches high : leaves from 

 oblong-ovate or oblong-lanceolate below to linear above, ^ to 1 inch 

 long: flowers few (3 to 12) in a terminal cyme, rather large, the 

 lanceolate sepals 2 to 4 lines long, shorter than the petals : stamens 

 about 50 : styles 3 (rarely 4 or 5) : capsule attenuate upward, ex- 

 ceeding the calyx. 



Hypericum Schaffneri. Pale green, not glaucous : stems 4-angled, 

 G to 18 inches high, branched above : leaves narrowly lanceolate, atten- 

 uate from a clasping base, |^ to 1 inch long : flowers numerous, often 

 lateral along the elongated branches of the cyme ; sepals linear, H to 

 2 lines long, a little shorter than the narrow petals: stamens 5 to 10: 

 styles very short : capsule oblong, acute or acutish, 2 to 2^ lines long. — 

 Mountains near San Luis Potosi (607 Schaffner, in part) ; 73 Parry 

 & Palmer, in part. Allied to H. paniculatum and H. fastigiatum. 



Callirrhoe involucrata, Gray. At Lerios, Coahuila (86). 

 Also var. lineariloba. Gray, from the same locality (85). 



Callirrhoe pedata. Gray. In Burnet and Wilson counties, Texas. 



Malvastrum tricuspidatum, Gray. At Uvalde, Texas (104). 



Anoda hastata, Cav. (Including A. cristata, Schlecht.) At 

 Soledad, Coahuila (106"), and near San Luis Potosi (159 Schaffner) ; 

 76, 77 and 78 Parry & Palmer. 



Anoda parviflora, Cav. Near Morales (158 Schaffner). Most 

 readily distinguished from the last by the densely stellate-pubescent 

 fruit and yellow flowers. 



SiDA HEDERACEA, Gray, var. With coarsely-toothed leaves. At 

 San Lorenzo de Laguna, Coahuila (92). 



SiDA FASCICULATA, Torr. & Gray. At Sutherland Springs, 

 Wilson County, Texas (91). 



Sid A DIFFUSA, HBK. (S. JiUformis, Moric.) Both the typical 

 hairy form, from Sutherland Springs, Texas, and a rough-puberulent 

 variety, with broad-elliptical leaves, from Monclova, Coahuila (105) ; 

 also in the San Miguelito Mountains (167 Schaffner); 87 and 89 

 Parry & Palmer. This name is adopted in the Kew list, and three 

 seems to be no good reason for objection.
