﻿146 Rydberg: Notes on Rosaceae 



species in the southern part of the Pacific slope. Dr. Focke in his 

 final monograph in Bibliotheca Botanica calls it R. ursinus 

 Menziesii, making R. macropetalus the typical R. ursinus. 



Rubus vitifolius Cham. & Schlecht. was described from a branch 

 bearing only unifoliolate leaves, but the description of their texture 

 and pubescence does not agree with the common plant. As there 

 is a thin-leaved and less pubescent plant with pubescent fruit 

 growing in the region, and this agrees with the description of R. 

 vitifolius, I adopted that name without hesitation. It is also 

 without much doubt R. ursinus glabratus Presl. It is represented 

 by the following specimens: 



California: San Francisquito Creek, Santa Clara County, 

 1902, Ahrams 2433 ; Mt. Tamalpais, 1905, Rydberg 6245; Albion 

 Ridge, Mendocino County, 1903, McMurphy 275; Crystal Spring 

 Lake, 1903, Elmer 4664; Stanford University, 1902, Baker 857; 

 without locality, Kellogg &f Harford 223; San Bernardino, Parish 

 292; Mount Shasta, 1892, Palmer 2570. 



Rubus Helleri Rydb. As stated before, the common plant of 

 the Columbia region has glabrous fruit, but a few specimens col- 

 lected in that region have finely pubescent fruit and these have the 

 leaves much darker-green above and of a firmer texture. These 

 specimens are all from stations west of the Cascades. I believe 

 they represent a distinct species. As I found no available name 

 for it, I dedicated it to Mr. Heller, who has collected the best 

 specimens of the same. 



Washington: Montesano, 1898, Heller 3 ggo. 



British Columbia: Alberni, Vancouver Island, 1907, Rosen- 

 dahl 2041. 



Rubus Eastwoodianus Rydb. Not all the blackberries of Cali- 

 fornia have pubescent fruit. The glabrous-fruited specimens do 

 not belong, however, to R. macropetalus, for the fruit is very 

 much elongate and the leaflets are of a different shape. I think 

 they belong to a distinct species, which I had the pleasure to name 

 after one of the most enthusiastic and indefatigable botanists of 

 the western coast, who also acted as my guide on Mount Tamal- 

 pais, when the type was collected. 



California: Mount Tamalpais, 1905, Rydberg 6238; Pasa- 

 dena, 1903, George B. Grant 3670, doubtfully referred here; so also 

 Jomacha, San Diego County, Chandler 5223 in small part only.
