Identification. Pothos cylindricus belongs to subgenus Pothos , the Junghuhnii group and is very close to Pothos longipes Schott but differs from its sessile spadix and flowering only terminally on leafy branches. Pothos cylindricus is also very near to P. papuanus Becc. ex Engl. (also with a sessile spadix), but P. papuanus usually lateral on a sometimes sympodially branched short shoot in distal leaf and the spathe oblong-ovate to oblong-lanceolate ( Boyce and Hay 2001).

Distribution and ecology. Northwestern and eastern Sabah. Primary and secondary lowland to upper hill forest, often in well-drained positions, 40–900 m elev.
