Pothos luzonensis (C.Presl) Schott

Slender to rather robust, (heterophyllous?), root-climbing liane. Shoot system architecture unclear; eocaul and seedling not observed; flowering shoot much abbreviated, (foliage) leafless. LEAVES chartaceous to somewhat coriaceous, drying midgreen to brown with the mid-rib and (in larger leaves) primary venation yellowish; petiole 2–9 × 0.1–0.4 cm, slender, canaliculate, rounded abaxially, base decurrent, apex prominently geniculate, sheath distinct, prominent, erect, apically ligulate in young growth, ligule and sheath margins later scarious-disintegrating; blade 8–28 × 1–10 cm, narrowly to oblong or broadly falcate-elliptic, apex acuminate to long-falcate acuminate (the latter especially in broader leaves), apiculate, apicule later deciduous, base obtuse, largest leaves minutely peltate or, rarely, prominently cordate; primary lateral veins arising at 35–45°, 2 intramarginal veins per side, 2–15(–20) mm from blade margin, arising from just above base of the midrib, remaining ± parallel to margin, terminating at the tip of the blade. INFLORESCENCE several to many together at different stages from a reiterating flowering shoot; peduncle 2.5–22 × 0.1–0.4 cm, rather slender, curving or straight. Spathe 2–6 × c. 1 cm, oblong to narrowly oblong, base rounded, annularly inserted on to peduncle, apex acuminate. Spadix stipitate; stipe 3–18 × 0.5–1 mm, terete; fertile portion 7–18 × 0.5–0.3 cm, slender-cylindric, straight to markedly zigzagging. Flowers c. 1.8 mm diam., widely scattered, arranged in a lax spiral along the spadix sometimes on a low ‘receptacle’, with 6 free tepals and 6 stamens. INFRUCTESCENCE with few berries; fruit (immature) 6–9 × 4–6 mm, oblong-ellipsoid; seeds not observed.
