No forms or varieties of N. densiflora 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. densiflora and three other related species.

N. densiflora

N. diatas

N. singalana

N. spathulata

The following natural hybrids involving N. densiflora have been recorded.
