Nepenthes diatas

Pitcher plant

An ultra-highland pitcher plant known only from the summit region of Mount Bandahara in Aceh, northern Sumatra, at about 2400–2900 m. It is a terrestrial, subscandent shrub of montane scrub and mossy forest, with a notably robust, woody-looking peristome. It needs the coldest conditions of any Sumatran Nepenthes in cultivation: cool days, cold nights, constant humidity and good light.

Where it grows wild

A terrestrial, subscandent shrub up to about 2.5 m tall growing in upper montane scrub and mossy forest near the summit of Mount Bandahara. Summit scrub is low and open, so plants get bright light, frequent cloud and cold, wet, windy air.

About 2400–2600 m, reaching up to 2900 m. There are no GBIF records with elevations.
