''Jamesbrittenia ramosissima'' (Hiern) Hilliard is a Southern African shrub in the family Scrophulariaceae occurring in the Northern Cape and southern Namibia, westward along the Gariep River from the vicinity of Augrabies Falls. It is one of some 90 species in the genus ''Jamesbrittenia'', ranging through Africa, with 74 species occurring in Southern Africa, and 1 in India. 〔http://www.theplantlist.org/1.1/browse/A/Scrophulariaceae/Jamesbrittenia/〕〔http://www.plantzafrica.com/planthij/jamesberg.htm〕 The genus is named for James Britten (1846-1924), medical student turned botanist, and acting Keeper of Botany at the British Museum when Kuntze named it. This extremely twiggy shrub ('ramosissima'), which grows to about 1m in height, bears a profusion of white or bluish-mauve flowers and is found growing under semi-desert conditions in cracks in sheetrock and on steep, bare, rocky slopes in very dry and hot locations bordering the Gariep River, from near the Augrabies Falls, through the Richtersveld to the vicinity of the river mouth. The branches of this shrub are woody and rigid, divaricate, and sometimes spinescent. The thick and rather fleshy leaves are alternate, shortly petiolate, obovate-cuneate to broadly ovate in shape, with a wedge-shaped base, margin toothed except at the base, about 2-6mm long by 2-6mm broad. 〔http://plants.jstor.org/taxon/sutera.ramosissima〕 Carl Ernst Otto Kuntze (1843–1907) in 1891 first published a description of the genus in "Revisio Generum Plantarum" 2: 461, based on the earlier description of ''Sutera'' by Albrecht Wilhelm Roth (1757–1834) in 1821. 〔http://www.tropicos.org/name/40037913〕 〔http://plants.jstor.org/person/bm000047393〕 〔http://www.zimbabweflora.co.zw/speciesdata/genus.php?genus_id=1269〕 The species was first described in 1904 as ''Sutera ramosissima'' by the botanist and mathematician William Philip Hiern in Harvey's Fl. Cap. 4: II. 265. (see illustration) Hiern's description was based on two specimens collected by Max Schlechter (1874-1960), and his more famous brother, Rudolf Schlechter (1872-1925). 〔http://www.ville-ge.ch/musinfo/bd/cjb/africa/details.php?langue=an&id=92807〕〔http://ia600603.us.archive.org/10/items/mobot31753002747027/mobot31753002747027.pdf〕 ==Gallery== Sutera ramosissima01.jpg| Jamesbrittenia ramosissima08.jpg| Jamesbrittenia ramosissima02.jpg| Jamesbrittenia ramosissima03.jpg| 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「Jamesbrittenia ramosissima」の詳細全文を読む スポンサード リンク
