''Orphium'' is a plant genus in the Gentian family (Gentianaceae), endemic to South Africa. The name derives from the legendary Greek musician Orpheus.〔Chittenden, Fred J. Ed., Royal Horticultural Society Dictionary of Gardening, Oxford 1951〕 The genus contains a single accepted species, ''Orphium frutescens'', commonly known as the ''sea rose''. Orphium arenarium C.Presl has been proposed as another species, but data suggest that it is synonymous with ''Chironia arenaria'' E.Mey.〔(Plant List (2010). Version 1. Published on the Internet; http://www.theplantlist.org/ (accessed September 2013) )〕 ==Description== ORPHIUM E. Mey., Comm. Pl. 181 (1837); Hill & Prain in FC. 4, 1: 1095 (1909); Verdoorn in FSA. 26: 236 (1963)〔Dyer, R. Allen, The Genera of Southern African Flowering Plants”. ISBN 0 621 02854 1, 1975〕〔()〕 ''Orphium'' has the habit of an erect subshrub, virgately branched, more or less pubescent, with branches leafy to the apex. The leaves are opposite, sessile and rather crowded. They are fairly thick, slightly leathery and bluntly linear to narrowly cuneate Some of the flowers may be solitary, while some are borne in inflorescences in the form of lax cymes, borne terminally or in the axils of upper leaves. The calyx has five lobes fitting loosely round the base of the corolla. The tube is short and campanulate, with an annular, crenulate disk inside at the base. The calyx lobes oblong and mucronate, without a dorsal keel. The corolla is a vibrant candy pink, or rarely white, setting off the vivid yellow anthers. The corolla tube is as long as the calyx or slightly longer. The petals are oblong to nearly circular, slightly longer than tube. The stamens are inserted below mouth of tube. The anthers are erect, with a slight spiral twist. The ovary has a single locule with parallel placentation. The stigma is terminal and peltate. The fruit is a capsule that splits septicidally. 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「Orphium」の詳細全文を読む スポンサード リンク
