Nepenthes densiflora () is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of between 1700 and 3200 m above sea level. No forms or varieties of N. densiflora have been described. Taxonomy 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. densiflora and three other related species. Natural hybrids The following natural hybrids involving N. densiflora have been recorded. N. angasanensis × N. densiflora References Further reading Bauer, U., C.J. Clemente, T. Renner & W.
