Ruhus Randii (Bailey) Rydb. This may be a form or variety 

 of R. canadensis, but to me it seems unlikely. The slender sub- 

 herbaceous habit and light-green leaves and usually light-colored 

 stem suggest distinctiveness enough, especially as I have seen 

 them both growing in the same localities in the Little Moose Lake 

 region of the Adirondacks.

Procumbentes 



Riibus cymosus Rydb. Until lately there was in southern 

 Mexico only one species of Rubus of the northern dewberry type 

 with thin deciduous few-nerved leaves, viz., R. humistratiis. R. 

 cymosus, however, cannot be confused with R. humistratiis, for 

 in the former the prickles are stout, flat, and strongly curved, 

 but in the latter, straight and slender;, in the former the flowers 

 are several and cymose, in the latter usually solitary. R. cymosus 

 is known only from the type collection. 



Rubus oligospermus Thornber. This has been known for half 

 a century, but has been confused with R. trivialis and R. humifusus. 

 It does not have the solitary flowers of these two species, however, 

 nor the evergreen leaves of R. trivialis, nor the slender habit and 

 the weak straight prickles of R. humifusus. It was first collected 

 by Thurber on the Mexican Boundary Survey. The following 

 specimens belong to it.
