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.
The following names may represent hybrids involving Rubus hispidus and other blackberry species (given in parentheses): Rubus adjacens Fernald (R. setosus); R. fulleri L. H. Bailey (R. setosus); R. grandidens L. H. Bailey (R. setosus); R. harmonicus L. H. Bailey (R. setosus); R. jacens Blanchard (R. setosus); R. parlinii L. H. Bailey (R. setosus); R. persistens Rydberg (R. trivialis); R. spiculosus Fernald (R. setosus); R. tardatus Blanchard (R. setosus); R. tholiformis Fernald (R. setosus); R. trifrons Blanchard (R. setosus); R. zaplutus L. H. Bailey (R. setosus). See the entry for R. flagellaris for possible hybrids between it and R. hispidus."
