Nepenthes diatas

Description

Nepenthes diatas (from Indonesian diatas "above, on top") is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of 2,000–2,900 metres (6,600–9,500 ft) above sea level. Nepenthes diatas was formally described in 1997 by Matthew Jebb and Martin Cheek in their monograph "A skeletal revision of Nepenthes (Nepenthaceae)", published in the botanical journal Blumea. However, the name N. diatas had already been in use since at least 1994. No forms or varieties of N. diatas have been described.In 2001, Charles Clarke performed a cladistic analysis of the Nepenthes species of Sumatra and Peninsular Malaysia using 70 morphological characteristics of each taxon. The following is part of the resultant cladogram, showing "Clade 3", which comprises N. diatas and three other related species.
