Pothos dolichophyllus Merr.

Robust and vigorous, moderately ramified homeophyllous root-climbing liane to at least 5 m, but frequently greatly exceeding this. Shoot system rather poorly differentiated into adherent and flowering branches; eocaul and seedling not observed. LEAVES stiffly thinly-chartaceous, drying pale yellowish green; petiole 8–30 × 0.4–1 cm, slender to very stout, sheath prominent, extending to base of apical geniculum; blade 14–50 × 5.5–19 cm, ± pendulous, elliptic to oblong elliptic, rarely linear-elliptic, apex acuminate to obtuse, with a flexuous filiform mucro, base acute to rounded; primary lateral venation diverging at c. 60–80°, crossed by usually three intramarginal veins on each side of the midrib, these arising from near the base of the midrib and running more or less to the leaf tip. INFLORESCENCE solitary or a few together at the end of leafy, pendulous shoots; peduncle 16–25 × 0.4–1 cm, about equalling the petiole of the subtending leaf, extending by up to double in fruiting specimens. Spathe 13–27 × 2.5–5 cm, somewhat exceeding the spadix, narrowly lanceolate, distally somewhat twisted, membranous, green. Spadix sessile, 10–19 × 0.7–1.5 cm, slender to stout cylindrical, yellow at anthesis. Flowers 2–2.5 mm diam. with (4)–6, free tepals and (4)–6 stamens. INFRUCTESCENCE considerably elongated, to c. 30 cm long, pendulous, with many berries; fruit to c. 2.5 × 1.5 cm, ovoid, scarlet when ripe; seeds not observed.
