Taxonomy
Together with N. spectabilis, N. singalana is one of the most widespread and commonly collected of all montane Sumatran species of Nepenthes. Specimens of N. diatas, N. pectinata, and N. spathulata can be mistaken for this species. Nepenthes diatas has broader, more robust, rigid upper pitchers, with teeth conspicuous around the inner edge of the peristome rather than being restricted to near the column. Nepenthes pectinata has a larger, lanceolate leaf with a decurrent base, and the lid glands are usually sparser and restricted to the basal part of the midline. Nepenthes spathulata has sharply 4-angled stems in the climbing phase, and the peristome is greatly expanded at the sides.
