    General Description

    Terrestrial or hemiepiphytic, vine-like, sprawling, 1-1.3 m tall; stems often arching; internodes medium grey green to dark green, matte to weakly glossy, 3-4 mm diam., nodes conspicuously swollen, drying light greyish green to tan; cataphylls 3.5-6 cm long, medium green to green, bases brown, mostly deciduous. Leaves spreading, petiole 1.1-5.6 cm long (averaging 3.5 cm), narrowly and sharply sulcate, C-shaped, flat adaxially with sharp, erect margins, medium green, weakly glossy, drying light tan and light green to olive-green; geniculum only weakly swollen, sharply sulcate, drying concolorous to slightly darker than petiole; blade 5.2-17.6 cm long, 1.9-6.9 cm wide (averaging 12.6 4.6 cm), 1.9-3.5 longer than broad, 1.8-5.7 longer than petiole, oblong-elliptic to elliptic-obovate, with the lower half of the blade tapering to a cordulate base, thinly coriaceous, weakly bicolorous, dark green and matte-subvelvety to weakly glossy above, moderately paler and matte below, upper surface drying yellowish brown to greyish green, lower surface light greenish brown to medium green; midrib bluntly acute, narrowly raised and concolorous above, narrowly round raised and slightly paler below, drying slightly darker to concolorous above, slightly lighter to concolorous below; basal veins 2-3 pairs (rarely 4 pairs), 1st and 2nd free to base, 3rd and 4th sometimes coalesced 3-4 mm; primary lateral veins 4-6 pairs, scarcely more prominent than interprimary veins, departing midrib at a 40-55° angle, weakly quilted, sunken to weakly raised in valleys above, prominently and narrowly raised below, drying slightly darker to concolorous above, slightly lighter to concolorous below; tertiary veins weak to distinct, slightly darker than surface, in part etched and moderately obscure to moderately prominent above, in part weakly raised below; collective veins arising from 1st basal vein, 7-13 mm from margin at base to 1st primary lateral vein, 5 mm from margin at 2nd primary lateral vein, gradually getting closer to margin as it nears apex. Inflorescence erect-spreading; peduncle 6.2-12.3 cm long (averaging 8.7 cm), acutely flattened on one side with 2 ribs, spreading with the spadix turned upward usually at a 90° angle to the peduncle; spathe 2-5 cm long, 3-7 mm wide (averaging 3.5 cm 5 mm), spreading at 90° angle to peduncle, medium green to green, weakly glossy; spadix sessile or stipitate to 2-3 mm, 2.5-5.9 cm long (averaging 4.1 cm), pale green to dark green, weakly glossy, 3.5 mm diam.; pollen pale yellow to white; pistils acute, dark green, semiglossy. Flowers 4 visible per spiral, 1.8-1.9 mm long, 1.6-1.7 mm wide; tepals semiglossy, drying conspicuously granular, yellowish green; lateral tepals mostly 2-sided, sometimes 3-sided, inner margins rounded, thin and scarious-undulate. Berries dark green, glossy, early emergent, round at apex.
