General Description
Lianas, to 10m, but frequently smaller, slender to rather robust. Stems 0.7–2.5cm in diam., terete in cross section; climbing stems with internodes elongated and rooting; free lateral stems forming a complex series of branches eventually pendent under their own weight. Leaves scattered, with 1 foliage leaf at each node except for proximal part of a branch where first few nodes possess a prophyll and 1 or more cataphylls instead of foliage leaves; petiole 9–33cm, shallowly channeled, apical pulvinus indistinct; petiolar sheath reaching base of leaf blade; leaf blade pale to strikingly glaucous green abaxially, dull mid-green adaxially, ovate in outline, ± symmetric, 11.5–42 × 7.5–24cm, base truncate, oblique, or shallowly cordate, apex acuminate, variously pinnatifid, pinnatipartite, or pinnatisect, depending upon degree of maturity; pinnae 2–5(–8) per side, each pinna with 3 conspicuous primary lateral veins. Inflorescences erect, solitary, arising from tips of free lateral branches; peduncle spreading, apical part curved, 10–25cm. Spathe opening wide, pale glaucous green in bud, opening pale to mid-yellow, waxy, oblong-ovate, 4.5–8.5 × 0.8–1.3cm, apex acuminate. Spadix sessile, dull cream-colored, cylindric, 4.5–8.5 cm, 0.8–1.3cm in diam. at widest point, base slightly tapering, apex truncate-rounded. Stamens 4 per flower; filaments flat, 2.7–3 × 0.8–1.5mm, not increasing in length at anthesis; pollen simply expelled from between pistils. Pistils 3–5.5mm, apex 3–4mm wide, truncate, smooth; stigma flat, circular to elliptic, 0.6–1mm; ovules numerous, on 2 intrusive parietal placentae. Infructescence 12–15 × 3–3.5cm when ripe, subtended by persistent withered spathe remains early in development; stylar tissue on ripening falling as irregular plates to expose ovary cavities with seeds embedded in copious, pale orange pulp. Seeds numerous per ovary, narrowly ellipsoid, 1.5–2 × ca. 1mm.
Phenology
Fl. Aug–Sep.
Habitat
Montane broad-leaved forests, trees.
