''Nepenthes hispida'' (; from Latin: ''hispidus'' "bristly") is a tropical pitcher plant species native to Borneo. It grows at elevations of 100 to 800 m in ''kerangas'' forest.〔Clarke, C.M. 1997. ''Nepenthes of Borneo''. Natural History Publications (Borneo), Kota Kinabalu.〕 It is known with certainty only from Lambir Hills National Park and surrounding areas.〔Clarke, C.M. & C.C. Lee 2004. ''Pitcher Plants of Sarawak''. Natural History Publications (Borneo), Kota Kinabalu.〕 ''Nepenthes hispida'' is listed as Conservation Dependent on the 2006 IUCN Red List of Threatened Species. In the wild, ''N. hispida'' is only known to hybridise with ''N. reinwardtiana''.〔〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 ==Description== The stem of ''N. hispida'' grows to 6 m in length and 6 mm in diameter. The cylindrical internodes are up to 15 cm long. Leaves are sessile and coriaceous in texture. The lamina is oblanceolate-oblong in morphology and can measure up to 28 cm long and 4 cm wide. The apex of the lamina is acuminate-obtuse and often unequal. The base of the lamina is attenuate, amplexicaul, and often decurrent. Three longitudinal veins run along the lamina on each side of the midrib. Pennate veins are indistinct. Tendrils grow to 15 cm in length.〔 The pitchers of ''N. hispida'' are rarely more than 15 cm high and 8 cm wide. They are ovoid-ellipsoid in the lower parts and sub-cylindrical in the upper parts. Aerial or upper pitchers are more cylindrical than lower or terrestrial pitchers. Two fringed wings, up to 3 mm wide, run down the front of the pitchers. These wings are often absent in upper pitchers. The opening or mouth of the pitcher is ovate and oblique. The peristome is rounded and up to 12 mm wide. The lid or operculum is ovate-elliptic. An unbranched spur, up to 5 mm long, is inserted at the base of the lid.〔 ''Nepenthes hispida'' has a racemose inflorescence. The peduncle is up to 5 cm long and 1.5 cm thick. The rachis is attenuate and may grow to 10 cm in length. The partial peduncles, which are up to 8 mm long, are two-flowered at the base only, otherwise one-flowered. Sepals are elliptic and up to 4 mm long. Male and female inflorescences are of similar structure.〔 A very dense indumentum of bristle-like, purple-grey hairs covers the stem. A sparser covering of shorter hairs is present on the inflorescence. Hairs on the surfaces of the leaves are apparently caducous, or shed at an early stage of development.〔 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 hispida」の詳細全文を読む スポンサード リンク
