About

Nepenthes lamii is a tropical pitcher plant endemic to New Guinea, where it grows at an altitude of up to 3,520 m above sea level, higher than any other Nepenthes species. Although once confused with N. vieillardii and previously regarded as conspecific with the closely related N. monticola, it is now recognised as a distinct species.

The specific epithet lamii honours Dutch botanist Herman Johannes Lam, who made one of the earliest known collections of this species.

Where it grows

Nepenthes lamii is endemic to the higher peaks of central Papua province in West Papua, New Guinea, including Doorman Top (also known simply as Mount Doorman) and Mount Erica of the Hellwig Mountains. Sizable populations of this species have been found near Tembagapura, a mining town situated at around 1,900 m in the Sudirman Range. Nepenthes lamii has an altitudinal distribution of 1,460–3,520 m above sea level. The uppermost altitudinal limit of this species represents the highest known elevation of any Nepenthes, although Nepenthes sp. Papua has been found at similar altitudes of around 3,500 m.
