Rubus roribaccus has a thick stem, round in cross-section and with straight prickles. Leaves are compound with 3 or 5 leaflets. Fruit is black, spherical or slightly oblong.[3]
The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.[6]
