Nomenclature
SUMMARY
Herbs hemiepiphytic, somewhat scandent. Internodes yellow-green, 2 – 6 cm long, 1 – 1.7 cm in diam., drying dark brown, matte, densely pale short-lineate. Cataphylls 3.5 – 8.5 cm long, persisting as reddish brown fibres with fragments of epidermis at upper nodes. Petiole subterete, 9 – 26.5 cm long (averaging 16.5 cm), narrowly and bluntly sulcate, drying densely pale short-lineate; leaf blade semi-glossy, yellow-green and much paler on lower surface, dark green on upper surface, drying slightly paler and weakly glossy on lower surface, grey and matte on upper surface, oblong-elliptic, 17.5 – 32.5 cm long, 8.6 – 12.5 cm wide, 2 – 3.5 × longer than wide (averaging 3 × longer), 1.1 – 1.9 × longer than petiole (averaging 1.6 × longer), subcoriaceous, base acute to rounded, apex acuminate; lower surface moderately smooth, dark glandular punctate; upper surface smooth without minute granulations, dark glandular punctate; punctations on both surfaces raised, especially on upper surface; midrib prominent on both surfaces, paler than surface; primary lateral veins (9 – )11 – 13( – 15) pairs, arising at 65° – 75° angle, narrowly prominent on lower surface, etched on upper surface, equalling collective vein; collective veins typically arising on each side from pair of basal veins, sometimes arising from one of lowermost primary lateral veins, 7 – 11 mm from margin, moderately loop-connecting primary lateral veins, sunken on upper surface. Inflorescence erect; peduncle medium green, sometimes purplish, drying dark brown, weakly glossy, c. 49 cm long, c. 5 mm in diam., much longer than leaves; spathe erect-spreading, green, 10.5 – 14 cm long, 10 – 13 mm wide; spadix olive-green, matte, long tapered, 9.5 – 12.8 cm long, more than 3 mm in diam. when dried, apex bluntly acute. Flowers 3(or 4) visible per spiral, 3.2 – 3.6 mm long, 2.2 – 2.4 mm wide, drying yellowish green, matte; tepals widely spaced around pistil, moderately smooth outside, densely punctate on inner surfaces; lateral tepals 2 – 2.3 mm wide, outer margin obtusely 2-sided, inner margin straight to weakly concave, thin and sometimes erose; stamens not emergent; anthers c. 0.6 mm wide; pollen pale yellow. Infructescence: peduncle arching with spadix pendent. Berries orange-red, depressed at apex, broader in one dimension.
