128 Rydberg: Notes on Rosaceae 



Specimens which I refer here rather than to R. eriocarpus have 

 been collected in Mexico. These are not typical and may repre- 

 sent a distinct species, closer, however, to R. glaucus than to R. 

 eriocarpus. 



Costa Rica: Buena Vista, 1903, Cook & Doyle 36; 1874, 0. 

 Kuntze. 



Guatemala: Tres Cruces, 1889, John Donnell Smith 1622. 



Specimens collected near Cuernavaca, State of Morales, 

 Mexico, by Rose and Hough are remarkable, not only for the 

 station at which they were collected, this being much further 

 north than the formerly known range extended, but also for the 

 large size of the leaves, the leaflets of some of the leaves of the 

 stem being up to 15 cm. long, and for the more glandular pedicels. 



MoRELOs: Cuernavaca, May 27-30, 1899, Rose & Hough 

 4410, 4414. 



Ruhiis eriocarpus Liebm. This as well as the preceding has 

 been determined as R. occidentalis , which is not found in any 

 part of Mexico or Central America. All so named belong to one 

 of the three species of R. glaucus, R. eriocarpus, or R. Pringlei. 

 The following specimens belong to R. eriocarpus: 



Vera Cruz: Vera Cruz, 1901, Rose df Hay 6183; San Miguel 

 del Soldado, 1899, Pringle 8 113; Jalapa, 1899, Rose & Hough. 



Oaxaca: Chinantla, Liebman i6q2. 



Panama: El Boquette, 1911, Pittier 3135. 



Ruhus Pringlei Rydb. This has also been confused with R. 

 occidentalis. Focke in 1891 described it as var. grandiflora, but 

 twenty years later, having evidently forgotten its first name, re- 

 described it as var. mexicana. It is evidently the same as de- 

 scribed in 1839 by Schlechtendal as var. incisus, but neither of 

 these varietal names could be used as specific. Therefore, I 

 took the pleasure of naming the species after Mr. C. G. Pringle, 

 who has collected the best specimens of this I have seen. 



Hidalgo: Pachuca, 1899, i?05e & Hough 4463; 1901, Rose & 

 Hay S553- 



Oaxaca: Sierra de San Felipe, Pringle 4686; Salazar, 1903, 

 Rose & Painter 7008. 



Mexico: between Toluca and Mexico- Ci^y, June 28, 1910, 

 Rushy 317.
