    General Description
    Stem epigeal, pleionanthic, to c. 30 cm long, c. 8 mm diam., decumbent, creeping to trailing, internodes c. 1–3 cm long. Leaves 1–6 per module; petiole c. 15 cm long, c. 3 mm diam., the margins minutely alate and sometimes crisped, slightly asperous, minutely hairy/spinulous (hand lens required), pale green to purplish, sheathing in the lower ½–¾; wings of sheath fully attached, tending to degrade at least in the upper half, becoming dark brown and flaking shortly after the emergence of the enclosed leaf, c. 5 mm wide, more or less straight, tapering, not ligular; blade c. 9–12 cm long × c. 4–6 cm wide, pale to mid-green, slightly glossy to dull, not variegated, usually tinged bronze when young, (elliptic to) ovate, widest about the mid-point, the base obtuse to rather weakly cordate with posterior lobes (0–) c. 8 mm long, the tip acute to weakly acuminate, the margin smooth to weakly undulate; midrib abaxially prominent, with 6–9 primary lateral veins on each side, diverging from the midrib at 50–70°, c. 1 cm apart; interprimary veins irregularly present; secondary venation flush adaxially and abaxially, arising from the midrib and the bases of the primary veins; tertiary venation not or faintly visible adaxially, visible abaxially, forming a tessellate reticulum. Inflorescences 1–5 together; peduncle to c. 5 cm, thin, 2.5 mm diam., erect at anthesis, then dangling. Spathe 5.5–7.5 cm long; lower spathe narrow ovoid, to 3.5 cm long, c. 1.5 cm wide, green; limb persistent until well after anthesis, then deliquescing, lanceolate, acuminate tipped, opening only slightly, the distal portion remaining convolute, with only the ventral part of the male zone exposed. Spadix 5–6 cm long; female zone 2–2.5 cm long, more or less cylindric, slightly curved towards dorsal side of spathe, obliquely inserted to adnate for c. ⅓ its length; pistils c. 0.75 mm diam., globose-polyhedral, pale green, somewhat distant and sometimes patchily distributed; style nil; stigmas globose; interpistillar staminodes numerous, irregularly distributed, c. 1 mm high, larger than the pistils, globular, very shortly stalked, white; sterile interstice 1–1.3 cm long, cylindric to slightly tapering, 5–8 mm thick, partly naked, consisting proximally of rather crowded structures resembling interpistillar staminodes, distally of scattered groups of much smaller staminodes resembling the stamens; male zone c. 1.5 cm long, 5 mm thick, cylindric to slightly spindle-shaped, the lower part corresponding with the spathe constriction; stamens dumbbell-shaped, c. 1 mm across, with the connective rather slender, slightly shorter than the thecae; pollen dusty, white; appendix very short, 3–5 mm long, conic; staminodes of appendix columnar, ivory white, c. 1 mm diam. Fruiting spathe declinate, urceolate.
    Habitat
    In lowland and hill rainforest, in damp places and occasionally along streams (but not properly rheophytic)
    Distribution
    Malesia: widespread in Peninsular Malaysia; a single collection from each of Aceh and North Sumatera provinces in Sumatera.
