''Nepenthes klossii'' is a tropical pitcher plant endemic to New Guinea. ==Botanical history== ''Nepenthes klossii'' was discovered in southwestern New Guinea during the Wollaston Expedition of 1912–1913. The type specimen of the species, ''Kloss s.n.'', was collected by Cecil Boden Kloss near an expedition campsite (camp VIb) on 26 January 1913, at an elevation of between 930 and 1170 m above sea level.〔〔 It is deposited at the herbarium of the Singapore Botanic Gardens.〔Schlauer, J. 2006. (''Nepenthes klossii'' ). Carnivorous Plant Database.〕 The specimen is of unknown sex as it lacks floral material.〔 In August 1916, ''N. klossii'' was formally described by Henry Nicholas Ridley in a report on the Wollaston Expedition published in ''The Transactions of the Linnean Society of London''.〔 The specific epithet ''klossii'' honours Cecil Boden Kloss, who first collected it three years earlier. Ridley wrote of this species:〔 A revised description and illustration of ''N. klossii'' were published in 1928 in B. H. Danser's seminal monograph "The Nepenthaceae of the Netherlands Indies".〔Danser, B.H. 1928. (21. ''Nepenthes Klossii'' RIDL. ) In: The Nepenthaceae of the Netherlands Indies. ''Bulletin du Jardin Botanique de Buitenzorg'', Série III, 9(3–4): 249–438.〕 Based on an examination of the ''N. klossii'' type specimen, Danser pointed out that Ridley had described the lower surface of the leaf as the upper surface and ''vice versa''.〔 The illustration from Danser's monograph does not accurately show the hooded shape of the pitcher or the lateral insertion of the mouth;〔Clarke, C.M. 2006. Introduction. In: Danser, B.H. ''The Nepenthaceae of the Netherlands Indies''. Natural History Publications (Borneo), Kota Kinabalu. pp. 1–15.〕 this would only be demonstrated in Matthew Jebb's 1991 monograph, "An account of ''Nepenthes'' in New Guinea".〔〔Jebb, M.H.P. 1991. An account of ''Nepenthes'' in New Guinea. ''Science in New Guinea'' 17(1): 7–54.〕 With regards to the intrageneric relationships of ''N. klossii'', Danser wrote: "This insufficiently described species seems to be closely related to ''N. stenophylla'', but I dare not unite these two." However, Danser's description of ''N. stenophylla'' was based on the type specimen of ''N. fallax'', a species considered by some to be distinct from the former.〔Clarke, C.M. 1997. ''Nepenthes of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕〔Schlauer, J. 2006. (''Nepenthes fallax'' ). Carnivorous Plant Database.〕 Danser placed ''N. klossii'' in the ''Regiae'' clade together with 14 other species. He wrote: "Very closely related, but certainly distinct species are in the first place ''N. Veitchii'', ''N. stenophylla'', ''N. Klossii'' and ''N. fusca''."〔 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 klossii」の詳細全文を読む スポンサード リンク
