Rubus kennedyanus is a bristly shrub. Leaves are compound with 3 or 5 egg-shaped leaflets, each leaflet with a distinctive long, narrow tip at the end. Flowers are in small groups of 1–3.[3][4]

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.[5]
