Veiy near Rubus aculeatifloms HAYATA, but separable from it in having 

 much longer unarmed peduncles, in the half-closed flowers with the calyx 

 which is afforded with minute pricldes on the back but quite destitute of any 

 glandular seta, and by the leaves which are cordate at the base ; in R. acu- 

 leatiflorus HAYATA, the leaves are truncate at the apex of the petioles and 

 slightly cordate towards the outer sides.
