Rubus hispidus L.[FNA9, HC2]
bristly dewberry, swamp dewberry

Publication: Sp. Pl. 1: 493.

Origin: Introduced

selected vouchers: WTU

Notes: Draft FNA9: "Rubus hispidus is best identified by its creeping primocanes with somewhat lustrous, coriaceous, and small, perennial leaves that persist through the winter until early spring, and an armature of hispid hairs or rarely weak, slender prickles. Non- or weakly evergreen plants may be evidence of introgression with R. flagellaris or R. setosus. See discussion under R. flagellaris for the superficially similar R. caesius.
