Nepenthes adnata

Nepenthes adnata is a small tropical pitcher plant endemic to West Sumatra in Indonesia, where it grows at elevations of 600 to 1200 metres on mossy sandstone cliff faces among dense vegetation in a moist, diffusely lit habitat. The epithet adnata is Latin for broadly attached and refers to the base of the leaf blade. Willem Meijer first collected it on 24 August 1957 near the Tjampo river, and the type specimen is kept at the National Herbarium of the Netherlands in Leiden. Mitsuru Hotta and Rusjdi Tamin described it in 1986, but without a Latin diagnosis the name was invalid until Jan Schlauer supplied one eight years later. The climbing or drooping stem rarely exceeds 2 metres, and the ovoid to cylindrical pitchers reach only about 10 centimetres, speckled with reddish-purple blotches and usually with a dark purple rim. Only two collections are known, and the one easily reached population is very small and frequently visited by collectors, and fires lit to clear forest for agriculture may threaten the habitat.
