R. lasiostylus is allied to several Asiatic species, all with 
more or less erect stems, white-tomentose undersurface of 
the leaves, long calyx-lobes, small red petals, and villous 
carpels. Of these two, R. niveus, Wall., and R. lasio- 
carpus abound in the temperate regions of the Himalaya; 
both are extremely variable, and their forms have given 
origin to many species, some of which are founded on 
specimens, not even on varieties. In both the ripe carpels 
are either dry or fleshy, and the endocarp of the fruit is 
lacunose; both are usually much more strongly armed 
plants than is #. lasiostylus, but they are very variable in 
this respect. | 
R. lasiostylus is a native of China, wheré it was dis- 
covered in the Province of Hupeh, by Augustine Henry, 
Esq., F.L.S., in 1888 ; since which period Mr. Hemsley in- 
forms me that very large numbers of Chinese species of 
ftubus have been added to the Kew Herbarium, bringing the 
total up to about sixty. Judging from his, and having 
regard to the extent of country in China that is botanic- 
ally unexplored, especially the mountain regions, there can
