Nepenthes rhombicaulis is a climbing tropical pitcher plant from the mountains of North Sumatra, notable for very long stems that can reach 35 m. It is grown as a high-humidity, warm, shade-tolerant houseplant or greenhouse plant, ideally in a terrarium or hanging basket where it can climb.
Nepenthes rhombicaulis is a tropical pitcher plant endemic to Sumatra. The specific epithet rhombicaulis is formed from the Latin words rhombicus, meaning "rhomboid", and caulis, "stem". It refers to the cross-sectional shape of the stem internodes.
Nepenthes rhombicaulis is known from a number of peaks in the Indonesian province of North Sumatra, particularly around Lake Toba. Plants that appear to match the description of N. rhombicaulis have also been recorded from Mount Bandahara in Aceh. The species is known with certainty only from the Mount Pangulubao complex and Mount Lubukraya, although Shigeo Kurata suggested that it is likely to be more widespread in the Lake Toba region. Nepenthes rhombicaulis has an altitudinal distribution of 1,600–2,000 m above sea level.
