''Roscoea brandisii'' is a perennial herbaceous plant found in the state of Meghalaya, India.〔 Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but ''R. brandisii'', like other species of ''Roscoea'', grows in much colder mountainous regions.〔 ==Description== ''Roscoea brandisii'' is a perennial herbaceous plant. Like all members of the genus ''Roscoea'', it dies back each year to a short vertical rhizome, to which are attached the tuberous roots. When growth begins again, "pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves.〔 Plants are usually tall, occasionally shorter or up to . The first one or two leaves consist only of sheaths; the remaining 5–8(–11) leaves have curved (falcate) blades mainly long by wide (although lengths and widths outside this range are also found). The sheaths sometimes have small 'ears' (auriculate) at the junction of the blade and sheath, where there is also a small ligule, extending to about .〔 The stem (peduncle) of the flower spike (inflorescence) is held within the leaves. The bracts which subtend the flowers are more or less the same length as the calyx.〔 Each flower has the typical structure for ''Roscoea'' (see the diagrams in that article). There is a tube-shaped outer calyx, with a bluntly two-lobed apex. Next the three petals (the corolla) form a white tube, longer than the calyx, terminating in three purple lobes, a hooded upright central lobe, about long by wide, and two narrower side lobes, about long by about wide (which are sometimes fused). Inside the petals are structures formed from four sterile stamens (staminodes): two lateral staminodes form what appear to be small upright petals, which are by , with a non-central vein; two central staminodes are fused to form a lip or labellum, long by about wide. The labellum may or may not be split into two lobes at the end.〔〔 The single functional stamen has an anther, about long, with long spurs formed from the connective tissue between the two capsules of the anther. The seeds when they form are brown and somewhat elliptical.〔 ''R. brandisii'' resembles ''R. auriculata''. The two species are separated by lowlands in Assam and the Indian state of West Bengal. ''R. brandisii'' is usually smaller, with narrower falcate leaves and smaller purple flowers with a long white tube at the base.〔 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「Roscoea brandisii」の詳細全文を読む スポンサード リンク
