Discussion | Rubus spectabilis is a thicket-forming shrub that has relatively large and desirably edible fruit. The species is used as an ornamental primarily for its robust, showy flowers and is naturalized in parts of western Europe. It is sister to the Hawaiian endemic R. hawaiiensis A. Gray. See discussion under 36. R. ursinus for the uncertain application of the name R. menziesii Hooker. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Rubus setosus is identified by erect to arching, rarely creeping, not tip-rooting, terete primocanes, always setose but variable in density, and deciduous primocane leaves that are often palmately compound with five leaflets. Cultivated plants sometimes alternate from erect to creeping (or vice-versa) in successive years, depending on changing soil conditions. The following nothospecies names are based on putative hybrids involving Rubus setosus and: R. allegheniensis (R. ×abbrevians Blanchard, R. ×aculiferus Fernald, R. ×adenocaulis Fernald, R. ×angustifoliatus L. H. Bailey, R. ×ascendens Blanchard, R. ×atwoodii L. H. Bailey, R. ×clausenii L. H. Bailey, R. ×flavinanus Blanchard, R. ×frondisentis Blanchard, R. ×perspicuus L. H. Bailey, R. ×ravus L. H. Bailey); R. canadensis (R. ×miscix L. H. Bailey [based on R. ×peculiaris Blanchard (not R. peculiaris Sampaio)]); R. flagellaris (R. ×alter L. H. Bailey, R. ×arcuans Fernald & H. St. John, R. ×biformispinus Blanchard, R. ×bigelovianus L. H. Bailey, R. ×bracteolifer Fernald, R. ×jacens Blanchard var. specialis L. H. Bailey, R. ×laevior (L. H. Bailey) Fernald [based on R. permixtus var. laevior L. H. Bailey], R. ×multiformis Blanchard, R. ×setospinosus L. H. Bailey, R. ×severus Brainerd ex Fernald); R. hispidus (R. ×adjacens Fernald, R. ×grandidens L. H. Bailey, R. ×harmonicus L. H. Bailey, R. ×jacens Blanchard, R. ×parlinii L. H. Bailey, R. ×spiculosus Fernald, R. ×tardatus Blanchard, R. ×tholiformis Fernald, R. ×trifrons Blanchard, R. ×zaplutus L. H. Bailey); R. pensilvanicus (R. ×wisconsinensis L. H. Bailey).
