''Nepenthes hamiguitanensis'' is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1200–1600 m above sea level. Once thought to be a natural hybrid between ''N. micramphora'' and ''N. peltata'', this plant is now considered a species of possible hybridogenic origin.〔〔McPherson, S.R. 2010. (Four new species of ''Nepenthes'' ). Carnivorous Plants UK, October 11, 2010. 〕〔Guerini, M. 2011. Associazione Italiana Piante Carnivore.〕 It produces squat upper pitchers that vary greatly in pigmentation, from red speckled to yellow throughout.〔 The specific epithet ''hamiguitanensis'' is derived from the name of Mount Hamiguitan, to which it is endemic, and the Latin ending ''-ensis'', meaning "from". ==Botanical history== Although only formally described in 2010, this taxon was already known several years earlier. A herbarium specimen of ''N. hamiguitanensis'' was collected by Victor B. Amoroso and R. Aspiras on March 13, 2007, from the Mount Hamiguitan summit ridge, specifically the trail leading to San Isidro. This plant was growing in montane forest margins at an altitude of 1310 m. Designated as ''V.Amoroso & R.Aspiras CMUH00006494'', the specimen is deposited at the Central Mindanao University Herbarium (CMUH) in Musuan, Bukidnon, Mindanao, Philippines.〔 Thomas Gronemeyer, Volker Heinrich and Stewart McPherson〔 carried out field studies on ''N. hamiguitanensis'' and the other species of Mount Hamiguitan between July 22–24, 2008.〔 The taxon was subsequently identified as a natural hybrid between ''N. micramphora'' and ''N. peltata'' in McPherson's two-volume monograph, ''Pitcher Plants of the Old World'', published in May 2009.〔 Gronemeyer returned to the site with Andreas Wistuba〔 between February 13 and 14, 2010.〔 Numerous seedlings and mature, climbing plants of ''N. hamiguitanensis'' were observed, but no intermediate plants with lower pitchers were found.〔 These field studies on Mount Hamiguitan also included observations of ''N. micramphora'', ''N. mindanaoensis'', and ''N. peltata''.〔 ''Nepenthes hamiguitanensis'' was formally described by Thomas Gronemeyer, Andreas Wistuba, Volker Heinrich, Stewart McPherson, François Mey, and Victor B. Amoroso, in the second volume of McPherson's ''Carnivorous Plants and their Habitats'', published in July 2010.〔〔(''Nepenthes hamiguitanensis'' Gronem., Wistuba, V.B.Heinrich, S.McPherson, Mey & V.B.Amoroso ). International Plant Names Index (IPNI).〕 The herbarium specimen ''V.Amoroso & R.Aspiras CMUH00006494'' was designated as the holotype.〔 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 hamiguitanensis」の詳細全文を読む スポンサード リンク
