''Rubus fruticosus'' L. is the ambiguous name of a European blackberry species in the genus ''Rubus'' in the rose family. The name has been interpreted in several ways: *The species represented by the type specimen of ''Rubus fruticosus'' L., which is also the type specimen of the genus ''Rubus''. This specimen is considered to match the species ''R. plicatus'', in ''Rubus'' subgenus ''Rubus'', section ''Rubus''.〔 * Various species consistent with Linnaeus' original description of the species, which was based on a mixture of specimens now considered to match ''Rubus ulmifolius'' and ''R. plicatus'' *a species aggregate (group of similar species) ''Rubus fruticosus'' agg. that includes most of a group called either ''Rubus'' subgenus ''Rubus''〔 or ''Rubus'' section ''Rubus'': * * in a narrow sense, sometimes separated as the section ''Glandulosus'', with about 289 microspecies. In this sense the species aggregate does not include the type of the genus ''Rubus'', which is a hybrid. * * in a broad sense including subgenus ''Rubus'' sections ''Glandulosus'', ''Rubus'' (about 20 microspecies), and ''Corylifolii'' (about 24 microspecies).〔 Section ''Rubus'' are probably hybrids involving members of section ''Glandulosus'' with either ''R. idaeus'' or ''R. allegheniensis''.〔 Section ''Corylifolii'' are probably hybrids involving members of section ''Glandulosus'' with ''R. caesius''.〔 * * even more broadly as a ''nomen ambiguum'' including all the taxa in the subgenus (or section) ''Rubus'' ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rubus fruticosus」の詳細全文を読む スポンサード リンク
