''Nepenthes mollis'' (; from Latin: ''mollis'' = soft; referring to the covering of hairs),〔Phillipps, A. & A. Lamb 1996. ''Pitcher-Plants of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕 or the Velvet Pitcher-Plant,〔 is a tropical pitcher plant species native to Kalimantan, Borneo. It is known only from a single dried herbarium specimen〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Borneo''. Redfern Natural History Productions, Poole.〕 and is the sole recognised species in the genus ''Nepenthes'' of which the pitchers are unknown. The habitat of ''N. mollis'' is listed as dense forest on a steep slope at an altitude of 1,800 m.〔Danser, B.H. 1928. The Nepenthaceae of the Netherlands Indies. ''Bulletin du Jardin Botanique de Buitenzorg'', Série III, 9(3–4): 249–438.〕 The species is only known from Mount Kemul, the type locality, although a wider distribution is possible, as several higher neighbouring mountains remain unexplored.〔Clarke, C.M. 1997. ''Nepenthes of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕 Charles Clarke suggests that it may occur in mossy forest.〔 ''Nepenthes mollis'' 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 of this species have been described.〔 ''Nepenthes mollis'' has no nomenclatural or taxonomic synonyms.〔 Its conservation status is listed as Data Deficient on the 2006 IUCN Red List of Threatened Species. ==Discovery and type material== ''Nepenthes mollis'' has only been collected once, on October 17, 1925 by Frederik Endert on Mount Kemul in East Kalimantan. The plant was collected near the summit of the mountain, at an elevation of approximately 1,800 m. It was discovered during an expedition to central Borneo by the Forest Research Institute of Bogor (then known as Buitenzorg), on which Endert also collected ''N. fusca'' for the first time.〔 Endert, F.H. 1927. Botanisch en floristisch verslag. In: D.W. Buijs, H. Witkkamp, F.H. Endert, H.C. Siebers & D.F.K. Bosch. ''Midden-Oost-Borneo Expeditie 1925''. G. Kolff & Co., Weltevreden.〕 ''Nepenthes mollis'' was formally described in 1928 by B. H. Danser in his seminal monograph "The Nepenthaceae of the Netherlands Indies". Danser wrote of this species:〔 Though from this plant, collected by Endert on the last Borneo expedition, the pitchers are unknown, the other parts are so peculiar and differ from all other species in such a striking manner, that it seems allowed to me to base a new species on it. It was found on a steep mountain slope, covered with dense forest at 1800 m above sea level. It reminds one to the other species, discovered by Endert on the same mountain, ''viz. N. fusca'', by its colour and its red-brown indumentum, but it differs by its quite other leaf shape and nervation, and its still denser indumentum. The type specimen of ''N. mollis'', ''Endert 4282'', is deposited at Herbarium Bogoriense (BO), the herbarium of the Bogor Botanical Gardens. It consists of a stem with leaves and a male inflorescence. The pitchers and female flowers of this species are unknown.〔 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 mollis」の詳細全文を読む スポンサード リンク
