''Nepenthes campanulata'' (; from Late Latin: ''campānulātus'' "bell-shaped"), the Bell-Shaped Pitcher-Plant,〔Phillipps, A. & A. Lamb 1996. ''Pitcher-Plants of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕 is a tropical pitcher plant native to Borneo. It has also been reported from Palawan, the Philippines, though further field work is needed to confirm this identification.〔Clarke, C., C.C. Lee & V. Enar 2014. Observations of the natural history and ecology of ''Nepenthes campanulata''. ''Carnivorous Plant Newsletter'' 43(1): 7–13.〕〔Mey, F.S. 2014. (''Nepenthes campanulata'': natural history, ecology and expanded geographical distribution in Palawan, Philippines. ) ''Strange Fruits: A Garden's Chronicle'', 1 March 2014.〕 Forest fires destroyed the only known population of ''N. campanulata'' in 1983 and it was uncertain whether the species had survived elsewhere or was in fact extinct.〔Clarke, C.M. 1997. ''Nepenthes of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕 It was rediscovered in 1997, several hundred kilometres from the type locality. ''Nepenthes campanulata'' is provisionally listed as Data Deficient on the 2006 IUCN Red List of Threatened Species. ''Nepenthes campanulata'' has no known natural hybrids.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 No infraspecific taxa have been described.〔 ==Discovery and naming== ''Nepenthes campanulata'' was first collected on 9 September 1957,〔 on Mount Ilas Bungaan by A.J.G. 'Doc' Kostermans, the head of the Botanical Division of the Forestry Research Institute at Bogor, on the same expedition in which he collected the type material of ''N. mapuluensis''. Kostermans wrote the following account of his discovery:〔 I was working for the Forestry Department at that time in Sangkulirang and when I had finished I wanted to find out about a flowering rock, Ilas Bungaan, upriver. After 10 days walking I saw the yellowish rock for the first time. When we were there we discovered that the yellow colour was that of the leaves of a ''Nepenthes'' completely covering the steep face of the 50 m high rock. We cut a tree that fell to the rock and acted as a ladder and climbed up. The ''Nepenthes'' was not in flower or fruit, but we found caves in the rock and in the caves a couple of boat-like coffins with sculptured dog-head ends which contained decapitated skeletons. ''Nepenthes campanulata'' was described by Shigeo Kurata in 1973 based on a single specimen, ''Kostermans 13764'', deposited at the herbarium of the Singapore Botanic Gardens.〔 An isotype labelled "spec. nov.!" is held at the Museum National d'Histoire Naturelle in Paris. Two more isotypes are deposited at the New York Botanical Garden.〔( Specimen Details: ''Nepenthes campanulata'' Kurata (NY Specimen ID: 39331) ). The New York Botanical Garden.〕〔( Specimen Details: ''Nepenthes campanulata'' Kurata (NY Specimen ID: 39332) ). The New York Botanical Garden.〕 According to Kurata, the collector stated that the species was endemic to this single location "presumably owing to its habitat which is noted as sand and limestone walls at an altitude of 300 m".〔〔 The type material of ''N. campanulata'' lacks floral structures and these remained unknown until the species' rediscovery in 1997. 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 campanulata」の詳細全文を読む スポンサード リンク
