Nepenthes baramensis (Nepenthaceae) - a new species from north-western Borneo

Nepenthes baramensis, a new species from peat swamp and heath forests in north-western Borneo, is described. It is distinguished from related species on the basis of its modified pitchers, which facilitate a facultative mutualistic interaction with Hardwicke's Woolly Bat, Kerivoula hardwickii, which roosts in its pitchers and may provide the plant with a substantial proportion of its foliar nitrogen.
