Nepenthes hemsleyana

A lowland Bornean pitcher plant closely related to N. rafflesiana. It is famous for its long upper pitchers, where Hardwicke's woolly bats roost. The bats' droppings supply about a third of the plant's leaf nitrogen, and the pitcher's back wall reflects their echolocation calls. It grows in peat swamp and heath forest below 200 m and needs a hot, humid lowland setup.

Where it grows wild

A climbing pitcher plant of peat swamp forest and heath (kerangas) forest on poor, acid, sandy or peaty ground. Plants scramble up through the open, low canopy of these forests, and upper pitchers hang among the shrubs where bats find them.

Below about 200 m. The measured site is at 22 m.
