It has often been treated as a variety or subspecies of the closely related Eurasian ''Rubus idaeus'' (raspberry or European raspberry),〔USDA Plants Profile: (''Rubus idaeus'' subsp. ''strigosus'' )〕〔Plants of British Columbia: (''Rubus idaeus'' subsp. ''strigosus'' )〕 but currently is more commonly treated as a distinct species.〔Germplasm Resources Information Network: (''Rubus strigosus'' )〕〔Roland, A. E., & Smith, E. C. (1969, reprinted 1983). ''The Flora of Nova Scotia''. Halifax: Nova Scotia Museum.〕〔Grignon, T. (1992). The Dynamics of ''Rubus strigosus'' (Michx.) in Post-Clearcut Mixedwood and Softwood Forests of Nova Scotia. Thesis.〕 ==Classification== Botanists have long debated the taxonomic treatment of the Eurasian and American red raspberries, with some viewing all of these plants as members of a single, circumboreal species ''Rubus idaeus,'' and others recognizing two (or more) species within this group.〔Whitney, G. G. (1978). A demographic analysis of ''Rubus idaeus'' L. and ''Rubus pubescens'' Raf.: the reproductive traits and population dynamics of two temporally isolated members of the genus ''Rubus''. Ph.D. thesis, Yale University. 139 pp.〕〔Fernald doubted this distinction, but Bailey and many other authors rely on it.〕〔〔Freedman, B. (1989). ''Environmental Ecology: The Impacts of Pollution and Other Stresses on Ecosystem Structure and Function''. Academic Press, Inc., San Diego.〕 The two species share many similarities, and probably recently diverged from a common ancestor, leading to differences in taxonomic interpretation, particularly regarding the more intermediate eastern Asian plants. A common current treatment, followed here, is to classify the North American red raspberries as ''Rubus strigosus,'' and include only the Eurasian plants in ''Rubus idaeus.'' When the species are combined, as done in some recent publications, the Eurasian plants are ''Rubus idaeus'' ssp. ''idaeus'' (or ''Rubus idaeus'' var. ''idaeus),'' and the American plants ''R. idaeus'' ssp. ''strigosus'' (or ''R. idaeus'' var. ''strigosus).'' Different interpretations are also sometimes made regarding placement of various eastern Asian populations of this group, by some considered to represent additional varieties or subspecies, if not different species altogether. The most distinctive physical difference among these plants is usual presence of gland-tipped hairs on first-year canes, petioles, pedicels, and calyces of ''R. strigosus,'' lacking in ''R. idaeus.'' 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 strigosus」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
