98 Rydberg: Notes on Rosaceae 



Jalisco: Leon Dequet. 



Oaxaca: 1894, Pringle 5871. 



Guerrero: Chipancingo, 1903, Nelson 7068; between Chilapa 

 and Texla, 1894, Nelson 2168. 



Cercocarpus f other gilloides HBK. To this species the follow- 

 ing are to be referred. 



Puebla: Cerro de Paxtle, Pur pus 4200. 



Vera Cruz: Orizaba, F. Mueller. 



Cercocarpus Traskiae Eastw. has not been collected outside of 

 Santa Catalina Island, California. 



Cercocarpus mojadensis C. K. Schneider. To this belongs the 

 following specimens: 



Coahuila: Sierra Mojada, 1892, M. E. Jones 134; Sierra de 

 Plata, 1905, Pur pus 1059; San Lorenzo Canyon, 1905, Palmer 537. 



Cercocarpus Pringlei (C. K. Schneider) Rydb. This was 

 originally described as a variety of C. mojadensis, but I think it is 

 specifically distinct. 



Cercocarpus macrurus Rydb. This is the C. parvifolius of the 

 Klamath and Siskiyou region of California and Oregon. It is 

 nearest related to C. montanus Raf., differing in the longer leaves 

 with more numerous lateral veins and the large fruit. Although 

 the characters separating it from C. montanus on one hand and C. 

 Douglasii on the other are not so striking, it is geographically 

 separated from both, the former being limited to the Rockies and 

 the latter to central and southern California. The following 

 specimens belong to it : 



California: Siskiyou Mountains, 1880, Engelmann (fruit); 

 same locality, 1866, Henderson (flowers); Ashland, 1866, Henderson 

 259 (flowers and young fruit) ; Klamath River at Keno, Cusick 

 2835; Klamathon, 1903, Copeland 3504; no locality, Wilkes Expe- 

 dition 1167. 



Oregon: Weiner, 1898, Walpole 81; Barclay Springs, Modoc 

 Point, Coville 1523 in part. 



Cercocarpus montanus Raf. There have been two species con- 

 fused under the name of C. parvifolius Nutt. even from its first 

 description in the Botany of Beechey's Voyage by Hooker & Arnott. 

 These authors adopted Nuttall's manuscript name, but included 

 in their description not only Nuttall's type from the Rockies but
