''Nepenthes flava'' is a tropical pitcher plant endemic to northern Sumatra, where it grows in montane forest at 1800–2200 m above sea level.〔〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 The specific epithet ''flava'' is derived from the Latin word for "yellow" and refers to the typical colouration of the plant's upper pitchers and other vegetative parts.〔 ==Botanical history== ''Nepenthes flava'' entered cultivation several years prior to being described and was known from at least 2004 under the placeholder name "''Nepenthes'' spec. nov. Sumatra".〔Wistuba, A. 2004. (''Nepenthes'' spec. nov. Sumatra ). Wistuba.com. (page from April 15, 2004 )〕 The species was formally described by Andreas Wistuba, Joachim Nerz and Andreas Fleischmann in an issue of ''Blumea''〔 published on July 4, 2007.〔(''Nepenthes flava'' Wistuba, Nerz & A.Fleischm. ). International Plant Names Index (IPNI).〕 The description was based on cultivated plant material; ''Wistuba cult. Wistuba 100201'' was designated as the holotype. This specimen was collected at an altitude of 1800 m and is deposited at the National Herbarium of the Netherlands (L) in Leiden, together with an isotype.〔〔 The describing authors explained their choice of the specific epithet ''flava'' as follows:〔 The specific epithet ‘flava’ refers to the bright yellow colour of the upper pitchers and most of the lower pitchers. Climbing plants especially give the impression of a mainly yellow plant. A detailed and slightly modified description of ''N. flava'' appeared in Stewart McPherson's 2009 monograph, ''Pitcher Plants of the Old World''.〔 Whereas the type description mentions a basal crest on the underside of the lid,〔 McPherson writes that no appendages are present in either lower or upper pitchers.〔 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 flava」の詳細全文を読む スポンサード リンク
