Nepenthes treubiana

A lowland coastal pitcher plant from western New Guinea: the McCluer Gulf cliffs, the Fakfak peninsula and Misool. It climbs from sandstone slopes and cliffs at the sea shore into trees. Its lower pitchers are small and urn-shaped, and its upper pitchers are large (15–23 cm) and funnel-shaped. Grow it as a hot, humid lowland Nepenthes in bright light.

Where it grows wild

Warburg's type came from sandstone slopes directly at the sea shore on the McCluer Gulf, where the plant climbed into trees and flowered 6–9 m up. McPherson records it on the gulf's cliffs and along the Fakfak coast. It roots in thin humus on rock and climbs into sunlit scrub and tree crowns.

No GBIF records carry an elevation. All accounts place it on coastal cliffs and slopes, so it is a lowland plant, probably from sea level to a few hundred metres.
