R. corylifolius has the leaflets green underneath, usually large and broad; flowers not so numerous as in the last. - Hedges and thickets, flowering earlier.

R. carpinifolius has the leaflets green underneath, but not so broad, and more pointed than in the last, the stems more hairy; flowers not numerous. - Woods.

R. glandulosus has the leaflets as in the last, or sometimes broader, the stems with numerous stiff, glandular hairs mixed with the prickles. - Shady woods.
