''Aloe ferox'' (known as the Cape Aloe,〔〔 Bitter Aloe,〔〔 Red Aloe〔 and Tap Aloe),〔 is a species of arborescent aloe indigenous to southern Africa.〔(【引用サイトリンク】title=The ''Aloe ferox'' Plant )〕〔(【引用サイトリンク】title=''Aloe ferox'', African Flowering Plants Database )〕 It is one of several ''Aloe'' species used to make bitter aloes, a purgative medication,〔 and also yields a non-bitter gel that can be used in cosmetics.〔 ==Description== ''Aloe ferox'' is a tall, single-stemmed aloe, that can grow to in height. Its leaves are thick and fleshy, arranged in rosettes, and have reddish-brown spines on the margins with smaller spines on the upper and lower surfaces. The leaf surfaces of young plants are covered in spines, however, as they get taller and less vulnerable to grazing, the leaves begin to lose most of their spines except for those along the leaf margins. Its flowers are orange or red, and stand between above the leaves, in multi-branched inflorescences. It is a variable species, and plants may differ physically from area to area, due to local conditions. This aloe is frequently confused with the related ''Aloe excelsa'' species, to the north, and they do look very similar when fully grown. However the flowers are different, with the racemes of ''Aloe excelsa'' being far shorter and slightly curved. 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「Aloe ferox」の詳細全文を読む スポンサード リンク
