|synonyms_ref=〔〔 }} ''Scadoxus multiflorus'' (formerly ''Haemanthus multiflorus'') is a bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa. It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles. It is naturalized in Mexico and in the Chagos Archipelago.〔 It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable. There are three recognized subspecies. Strongly toxic like other ''Scadoxus'' species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine. Common names, some of which are used for other species, include blood lily, bloodflower, Katherine-wheel, oxtongue lily, and powderpuff lily.〔(【引用サイトリンク】title=USDA GRIN Taxonomy )〕 ==Description== ''Scadoxus multiflorus'' grows from a "rhizomatous bulb", i.e. a bulb which also produces rhizomes (thickened roots). The leaves and flower may appear together or the leaves may be produced later. The bases of the leaves, the stalks or petioles, are tightly wrapped together to form a pseudostem or false stem, long. The flowers are produced in an umbel at the top of a leafless stem (scape), long. Both the pseudostem and the scape are often covered with reddish brown to dark violet spots. The bracts under the umbel soon wither.〔 The umbel of flowers is more-or-less globe shaped, with from 10 to 200 individual flowers. Each flower has a stalk (pedicel) typically long. The tepals, filaments of the stamens and the style are all scarlet, fading to pink. The bases of the tepals are fused to form a cylinder-shaped tube, long; the free ends of the tepals are long, narrow and spreading. The fruit is a berry, across.〔 Differences between the three accepted subspecies have been summarized by Friis and Nordal, and are shown in the table below.〔 It can be seen that although the dimensions mostly overlap, the length of the flower tube relative to the free segments at the end of the flower distinguishes ''S. m.'' subsp. ''longitubus'', in which they are more-or-less the same length, from ''S. m.'' subsp. ''multiflorus'', in which the tube is generally shorter than the free segments. ''S. m.'' subsp. ''katherinae'' is intermediate. ''S. m.'' subsp. ''multiflorus'' tends to have narrower free segments than the other two subspecies. ''S. m.'' subsp. ''katherinae'' is tall, ''S. m.'' subsp. ''longitubus'' short, with ''S. m.'' subsp. ''multiflorus'' generally intermediate, although varying in height throughout its considerable range. 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「Scadoxus multiflorus」の詳細全文を読む スポンサード リンク
