Rydberg: Notes on Rosaceae 129 



Rubiis occidentalis L. This is confined to the United States 

 and Canada, east of the Rocky Mountains. Specimens from the 

 west which have been referred to R. occidentalis belong to R. 

 leucodermis Dougl., R. glaiicifolitis Kellogg, or R. bernardinus 

 (Greene) Rydb. This was made the type of the genus Melano- 

 bakis Greene. 



Rubus leucodermis Dougl. Melanobatus leucodermis Greene. 

 This takes the place of R. occidentalis west of the Rockies from 

 British Columbia and Montana to Utah and central California. 

 In southern California its place is taken by R. bernardinus. 



Rubus glaucifolius Kellogg. Kellogg's specific name was 

 adopted by Dr. Greene under Melanobatus, but the only specimens 

 seen labeled M. glaucifolius in Greene's handwriting are in his 

 private herbarium and were collected by himself at Eureka, 

 Siskiyou County. These specimens belong to R. leucodermis. 

 R. occidentalis and R. leucodermis are never glandular, while R. 

 glaucifolius and R. bernardinus are so in the inflorescence. The 

 following specimens belong here. 



California: Mt. Sanedrin, Lake County, 1902, Heller 6040; 

 Emigrant Gap, 1882, M. E. Jones, 330Q; Forest Ranch 1896, 

 Mrs. Austin 113; Mt. Pleasant, Spanish Peak Range, 1909, 

 Leiberg $161. 



Oregon: Rabbit Ears, south slope of Umpagre Divide, 

 Applegate 2643. 



Rubus bernardinus (Greene) Rydb., Melanobatus bernardinus 

 Greene. This is closely related to R. glaucifolius and perhaps not 

 specifically distinct. Its range is, however, much more southern. 

 Rusby's specimens from New Mexico are referred here doubtfully. 

 They are from a locality so far from the known range of the species 

 and no specimens of a black raspberry have been found anywhere 

 between Southern California and Rusby's station. To R. bernar- 

 dinus belong: 



California: San Bernardino Mountains, igoi, Parish 3046; 

 Strains Camp, Los Angeles County, 1902, Abrams 2584; Los An- 

 geles County, 1899, Chamberlain. 



New Mexico: MogoUon Mountains, July 15, 188 1, Rusby 123. 



Rubus nigerrimus (Greene) Rydb. This was originally de- 

 scribed as R. hesperius by Piper. As that name was pre-
