Very near Rubus taitcensis HAYATA, but distinguishable from it in having 

 glandular setas, besides prickles, on the under surface of the calyx-cups. Also 

 near Rubus mingetsensis HAYATA, but differs from it in having calyx with 

 glanduliferous seta? on the back and with shorter tails at the apex of the lobes, 

 and in the nearly glabrous petals, semiglobose receptacles, less pilose carpels, 

 nearly erect styles and aculeolate pedicels.
