''Rhododendron catawbiense'', with common names Catawba rosebay, Catawba rhododendron, mountain rosebay,〔 purple ivy,〔 purple laurel,〔 purple rhododendron,〔 red laurel,〔 rosebay,〔 rosebay laurel,〔 is a species of ''Rhododendron'' native to the eastern United States, growing mainly in the southern Appalachian Mountains from Virginia south to northern Alabama. It is a dense, suckering shrub growing to 3 m tall, rarely 5 m. The leaves are evergreen, 6–12 cm long and 2–4 cm broad. The flowers are 3-4.5 cm diameter, violet-purple, often with small spots or streaks. The fruit is a dry capsule 15–20 mm long, containing numerous small seeds. The species is named after the Catawba River.〔André Michaux. Flora Boreali'Americana. 1803. ("Hab. in montibus excelsis Carolinse septentrionalis; juxta originem amnis Catawba")()〕 ==Classification== ''Rhododendron catawbiense'' belongs to the ''Subgenus Hymenanthes'', within which it is further assigned to ''Section Ponticum'' and ''Subsection Pontica''. The latter — one of the 24 subsections of ''Ponticum'' — also contains about a dozen other species. The taxonomy has been confused by a tendency to group all large leaved Rhododendrons under the catch-all ''R. catawbiense''.〔(University of Connecticut: Rhododendron catawbiense )〕 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「Rhododendron catawbiense」の詳細全文を読む スポンサード リンク
