centimetre. The lid is suborbicular, truncate or slightly emarginate, and rounded or slightly cordate at the base. Round, depressed glands are present on the undersurface of the lid, being concentrated and increasing in size towards the middle. A flattened, unbranched spur (≤3 mm long) is inserted at the base of the lid. The male inflorescence is a long, cylindrical panicle. The peduncle reaches 12 cm in length and 4 mm in width. The rachis is attenuate and up to 44 cm long. Pedicels lack bracteoles, reach 55 mm in length, and are one- to four-flowered. Tepals are orbicular-elliptical and around 4 mm long. Stamens are about 4 mm long, including the anthers. The female inflorescence is a panicle-like raceme. The peduncle may be up to 15 cm long and 2.5 mm wide. The rachis is attenuate and reaches 20 cm in length. Pedicels are up to 35 mm long and most have filiform bracteoles. They are one- to three-flowered. Tepals are oblong-lanceolate and approximately 4 mm long. The ovary is sessile. Nepenthes neoguineensis has a very sparse indumentum. The stem is virtually glabrous, as is the lamina. Tendrils are densely hirsute when young, becoming only hairy near the pitcher or entirely glabrous when mature. Pitchers have a dense covering of caducous stellate hairs. The exception is the spur, which has persistent stellate hairs. Inflorescences have a very dense indumentum of short, white or brownish stellate hairs. The pedicels, tepals and the ovary are very densely stellate-tomentose. Lower pitchers range in colour from light green to dark purple throughout. Upper pitchers are generally yellowish-green, often with a darker peristome and bright red lid. Herbarium specimens are fallow-dun in colour. Ecology Nepenthes neoguineensis is native to New Guinea and the nearby D'Entrecasteaux Islands, and may also occur on Misool (see N. sp. Misool). The species is relatively widespread in New Guinea, ranging across the entire length of the island and occurring in both Papua New Guinea and the Indonesian portion of the island (Western New Guinea). As such, its conservation status is listed as Least Concern on the 2006 IUCN Red List of Threatened Species. Nepenthes neoguineensis grows on river edges, river gravel bars, ridge crests, and rarely in open grassland or disturbed forest. It has a wide altitudinal distribution, occurring from sea-level to an elevation of , occasionally . In the wild, N. neoguineensis occurs sympatrically with N. ampullaria and N.
