It closely resembles similar taxa like Rubus kumaonensis and Rubus rugosus. It can usually be distinguished from them by its taller height. In addition, it has "both leaf surfaces green, upper surface more hairy than lower surface, leaf blade margins biserrate, sepal deltoid, tomentose on both sides, margin with 7–10 appendages, apex bifurcate or trifurcate, petals spathulate, and calyx, corolla and stamens persistent in fruit." It grows as tall as 10 meters in height and flowers from August to November while fruiting/ripening from October–November.[1][3]
