''Ceraria namaquensis'', with the common names Namaqua porkbush and Namaqua portulacaria, is a species of succulent shrub, native to the border between South Africa and Namibia. 〔(The Plant List entry: ''Ceraria namaquensis'' —''Portulacaria namaquensis'' )〕 〔(Encyclopedia of Life entry: ''Ceraria namaquensis'' —''Portulacaria namaquensis'' )〕 〔(JSTOR entry: ''Ceraria namaquensis'' —''Portulacaria namaquensis'' )〕 The plant's current name is ''Portulacaria namaquensis'', due to recent phylogenetic studies have shown that it is in fact located within the genus ''Portulacaria''. 〔P.Bruyns, M.Oliveira-Neto, G.F. Melo de Pinna, C.Klak: ''Phylogenetic relationships in the Didiereaceae with special reference to subfamily Portulacarioideae''. Taxon 63 (5). October 2014. 1053-1064.〕 Its closest relative is the species ''Portulacaria armiana''〔〔(Cactus-art.biz )〕 ==Distribution== The natural habitat of this species extends along the Orange River valley, along the border between Namibia and South Africa. It has also been recorded near the coast slightly further north in Namibia. 〔''Annals of the South African Museum'' 9: 33. 1912. (Ann. S. African Mus.)〕 This is an extremely arid, winter-rainfall area. In cultivation, it requires extremely well-drained soil, and is usually grown grafted onto a root-stock of the more resilient Portulacaria afra. 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「Ceraria namaquensis」の詳細全文を読む スポンサード リンク
