''Nepenthes pitopangii'' is a tropical pitcher plant endemic to the Indonesian island of Sulawesi.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 Discovered in 2006, ''N. pitopangii'' was initially known from a single plant at a remote locality in Lore Lindu National Park. Efforts made in the following years to locate further populations on surrounding mountains proved unsuccessful.〔 In March 2011, a new population of ''N. pitopangii'' consisting of around a dozen plants was discovered more than 100 km from the type locality.〔McPherson, S.R. 2011. Discovery of a new population of ''Nepenthes pitopangii''. In: ''New Nepenthes: Volume One''. Redfern Natural History Productions, Poole. pp. 506–515.〕 ''Nepenthes pitopangii'' appears to be closely related to ''N. glabrata'', from which it differs most obviously in its upper pitcher morphology.〔〔 ==Botanical history== ''Nepenthes pitopangii'' was discovered by the British veterinarian Jonathan Newman during a birdwatching expedition through Lore Lindu National Park, Central Sulawesi, in September 2006.〔〔Newman, J. 2006. (Sulawesi Neps Part Three - save the best till last... ). Carnivorous Plants UK, October 19, 2006. 〕 Newman came across the plant "()hile trying to get closer to a roosting Diabolical Nightjar (diabolicus'' )", and initially thought it was ''N. eymae'',〔 another Sulawesi species that produces similarly shaped upper pitchers. The online publication of his trip report the following month〔 brought the taxon to the attention of botanists. Further habitat photographs of ''N. pitopangii'' were posted online in January 2008 by Alfindra Primaldhi, who found the plant independently, having not seen Newman's report.〔Primaldhi, A. 2008. (Sp Sulawesi ). Carnivorous Plants in the tropics, January 26, 2008.〕 In July 2007, Stewart McPherson and Greg Bourke visited the plant and determined that it represented a previously unknown species.〔(New Species - ''Nepenthes pitopangii'' ). Redfern Natural History Productions.〕 McPherson returned to the site with Ch'ien Lee in April 2008 to make further observations of the plant in preparation for its formal description.〔〔Pitopang, R. 2009. (Some New Records of Flowering Plant were Discovered ). Ramadanilpitopang’s Blog, February 24, 2009.〕 During these field trips, McPherson climbed three mountains near to the type locality, but was unable to find any additional specimens of ''N. pitopangii''.〔 The first detailed description of the species appeared in the second volume of McPherson's ''Pitcher Plants of the Old World'', printed in May 2009.〔 The formal description of ''N. pitopangii'' was published in the October 2009 issue of ''The Gardens' Bulletin Singapore''.〔〔(''Nepenthes pitopangii'' Chi.C.Lee, S.McPherson, Bourke & M.Mansur ). International Plant Names Index (IPNI).〕 The holotype of ''N. pitopangii'', ''RP 2054'', was collected by Rahmadanil Pitopang on May 30, 2007, from Lore Lindu National Park in Sulawesi, Indonesia.〔〔 It is deposited at the Herbarium Celebense (CEB) of Tadulako University.〔〔 This collection by Pitopang, the curator of Herbarium Celebense, represents the earliest herbarium material of this species, which was later named in his honour.〔〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Sulawesi''. Redfern Natural History Productions, Poole.〕 Due to the extreme rarity of ''N. pitopangii'', its type locality was not disclosed in the formal description.〔〔 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 pitopangii」の詳細全文を読む スポンサード リンク
