Nepenthes campanulata

Nepenthes campanulata was first collected on 9 September 1957, According to Kurata, the collector stated that the species was endemic to this single location "presumably owing to its habitat which is noted as sand and limestone walls at an altitude of 300 m". The type material of N. campanulata lacks floral structures and these remained unknown until the species' rediscovery in 1997. ==Description==

Nepenthes campanulata produces short, cylindrical, climbing stems 20 to 50 cm tall and 2 cm across. The apex of the lamina is rounded and slightly peltate. The base of the lamina is amplexicaul. Two to three longitudinal veins are present on each side. Pennate veins are inconspicuous. Tendrils are very short and stiff, rarely exceeding 4 cm in length. ==Distribution and habitat==

The population of N. campanulata from which the type specimen originated was destroyed as a result of forest fires in 1983. Nepenthes campanulata was at this time thought to have become extinct. However, the species was rediscovered in 1997 by Ch'ien Lee on the limestone cliffs of Gunung Mulu National Park in Sarawak, more than 400 km from the type locality. In July 2013, a taxon closely resembling N. campanulata was observed and photographed growing on the limestone cliffs of the Saint Paul formation, Palawan, the Philippines. Charles Clarke and Ch'ien Lee consider these plants likely to represent N. campanulata, or at least a close relative. Nepenthes campanulata is a lowland species, growing lithophytically at elevations of 100–300 m above sea level. It inhabits damp, mossy areas on cliff faces and appears to be endemic to limestone substrates. ==Taxonomy==

In his description of N. campanulata, Kurata suggested that it may be closely related to N. inermis, a Sumatran endemic. ==Notes==
