''Linnaea'' is a plant genus which has often been classified in the family Caprifoliaceae (the Honeysuckle family) but may be more accurately considered to belong to its own family, Linnaeaceae. The genus includes a single, generally boreal to subarctic woodland subshrub species, ''Linnaea borealis'', commonly known as twinflower (sometimes written twin flower). This plant was a favorite of Carl Linnaeus, founder of the modern system of binomial nomenclature, for whom it was named. ==Classification== The genus ''Linnaea'' is now considered to include only a single, circumboreal species, ''Linnaea borealis'', with three subspecies generally recognized: *''Linnaea borealis'' subsp. ''borealis'' - Europe *''Linnaea borealis'' subsp. ''americana'' - North America (formerly classified as the species ''Linnaea americana'') *''Linnaea borealis'' subsp. ''longiflora'' - Asia, and western North America (from Alaska to California) The genus ''Linnaea'' is usually treated in the Caprifoliaceae, along with ''Lonicera'', ''Symphoricarpos'', and related genera, but sometimes classified in its own family Linnaeaceae, along with such similar genera as ''Abelia'', ''Dipelta'', ''Kolkwitzia'', and ''Zabelia'', but not ''Lonicera'' or ''Symphoricarpos''. 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「Linnaea」の詳細全文を読む スポンサード リンク
