could be a hybrid between R. procumhens and R. hispidus, if the 

 leaves were not rather densely hairy. It is, therefore, best to re- 

 gard it as a distinct species.

Ruhus plicatif alius Blanch. This was first described by Aiton 

 as R. villosus, but there is an older R. villosus of Thunberg, and the 

 name is therefore not available. In this country the name R. 

 villosus Ait. has usually been applied to R. nigrohaccus, sometimes 

 to R. argutus. Professor Bailey discovered that the original R. 

 villosus Ait. was not a blackberry but a dewberry. Alton's plant 

 has decidedly pubescent leaves, but Professor Bailey did not think 

 this character was very important and therefore regarded it as a 

 form of R. procumhens to which he applied the name R. villosus. 

 R. plicatifolius is a northern plant, in the southern part of the 

 range, limited to the mountain regions.

Rubus ahoriginum Rydb. resembles in many respects R. Bailey- 

 anus, especially in the texture and pubescence of the leaves, the 

 foliaceous inflorescence, and the large flowers, but differs in the 

 absence of glandular hairs, and in the ovate instead of broadly 

 cordate terminal leaflet of the new shoots. The leaves of the in- 

 florescence are not so broad.
