Roots c. 0.25–0.33 mm in diam., mostly spreading through the leaf litter-soil interface. Leaf prophyll linear, up to 9 x c. 4 mm, acute; cataphylls oblong-lanceolate to linear triangular or triangular, up to 10 cm x 5 mm, attenuate to acute, prophyll and cataphylls at first membranous and pale green, soon darkening and drying papery; petiole 2.5–18 cm x 1–2 mm; leaf blade ovate to hastate or subsagittate, 10–21 x 3.5–8.5 cm, thinly coriaceous or coriaceous, even on the same plant, pale to dark green, occasionally with various greyish to pale green blotchy or/or cloudy markings adaxially, abaxial surface much paler, sometimes suffused reddish purple in which case primary mid-vein and primary lateral veins on abaxial surface purple-red, margins smooth, apex acute to acuminate, posterior lobes rounded to subacute, divergent to almost parallel, sometimes ± absent. Inflorescence (1)2–4 together held level with or below the leaves; peduncle 4–25 cm x 0.25–0.5 mm; spathe 2–7 cm long; spathe limb elliptic, 1.6–2.6 cm x 5–7 mm, apex acute to briefly attenuate, base decurrent into lower spathe; lower spathe margins clasping the ovaries, 4–8 x c. 1.5 mm; spadix 2.5–3.5 cm x 0.25–1 mm, free portion cylindric, up to 14 mm long, tapering apically into a greatly attenuated appendix to 9 mm long composed of connate synandrodes. Flowers synandria irregularly elongate in plan view, 2–3 x 0.5–1 mm; ovaries bottleshaped, 1.5 x 0.7 mm, two or three in a single row aligned longitudinally along the spadix axis; stigma capitate, c. 0.2 mm in diam., papillose; style very short. Infructescence carried on declinate to reflexed peduncle, enclosed by the persistent lower spathe, 2 cm x 4 mm, few-berried; berries more or less globular, ripening pale green, c. 4 mm in diam, stigmatic remains persistent, not prominent.
