''Nepenthes izumiae'' is a tropical pitcher plant endemic to Sumatra, where it grows in montane forest at 1700–1900 m above sea level.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 It appears to be most closely related to ''N. lingulata'' and ''N. singalana''.〔〔〔Lee, C.C., Hernawati & P. Akhriadi 2006. (Two new species of ''Nepenthes'' (Nepenthaceae) from North Sumatra ). ''Blumea'' 51(3): 561–568.〕 The specific epithet ''izumiae'' honours Izumi Davis, wife of Troy Davis, one of the describing authors.〔〔 ==Botanical history== The species was mentioned as an undescribed taxon in Charles Clarke's 2001 monograph, ''Nepenthes of Sumatra and Peninsular Malaysia'', under the name "''Nepenthes'' species B".〔 Clarke considered it to be most closely allied to ''N. singalana'', writing that "()urther research is required to determine whether or not this is simply an unusual variety of ''N. singalana'', or whether it warrants description as a distinct species".〔 Flowering-size specimens of ''N. izumiae'', identified as ''N. singalana'' from Mount Talakmau, were already in cultivation before the species was formally published.〔Mansell, G. N.d. (New ''Nepenthes'': ''Nepenthes izumeae'' ). Exotica Plants. 〕 ''Nepenthes izumiae'' was formally described by Troy Davis, Charles Clarke and Rusjdi Tamin in a 2003 issue of the botanical journal ''Blumea''.〔 ''Clarke, Davis & Tamin 1309'' was designated as the holotype. This specimen was collected in the Barisan Mountains, north of Bukittinggi, on July 13, 2000. It is deposited at the Herbarium Universitas Andalas (ANDA) of Andalas University in Padang, West Sumatra.〔〔(''Nepenthes izumiae'' Troy Davis, C.Clarke & Tamin ). International Plant Names Index (IPNI).〕 The next detailed treatment of ''N. izumiae'' appeared in Stewart McPherson's 2009 monograph, ''Pitcher Plants of the Old World''.〔 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「Nepenthes izumiae」の詳細全文を読む スポンサード リンク
