Small herb to c. 15 cm tall. Stem hypogeal, creeping, condensed near soil level, more elongate below, ?pleionanthic. Leaves c. 5 together in a rosette; petiole to c. 6 cm long, sheathing in the lower ¼, narrowly alate above the sheath, the wing crisped or not; wing of sheath fully attached, broad, apically truncate; blade narrowly ovato-sagittate, 8–11 cm long × 3.5–5.5 cm wide, dark green adaxially, paler abaxially, the apex acute, the base narrowly and rather shallowly cordate with posterior lobes 1–1.5 cm long; midrib adaxially somewhat prominent (dry) less so abaxially, with 5–8 primary lateral veins on each side, alternating with lesser interprimaries and diverging at c. 60°; secondary venation rather sparse, arising mostly from the midrib; tertiary venation forming a conspicuous tessellate reticulum abaxially and adaxially (dry). Inflorescences 1–2 together subtended by short broad cataphylls; peduncle to c. 4 cm long. Spathe c. 5 cm long; lower spathe c. 2 cm long, green, narrowly ovoid, c. 1 cm diam., differentiated from the limb by an abrupt constriction; limb ovate, inflated over the male zone and appendix of spadix, white, c. 3 cm long, caducous. Spadix 3.6 cm long, narrowly hourglass-shaped; female zone 1.6 cm long, adnate to the spathe in the lower c. ⅔, narrowly spindle-shaped; pistils somewhat lax; ovary subglobose, c. 1 mm diam.; stigma sessile, button-like, papillate, c. 0.3 mm diam.; interpistillar staminodes absent from among the pistils, confined to a row along the spathe-spadix adnation and concentrated in the sterile interstice, subsessile, truncate, drying scale-like, c. 1.3 mm across; sterile interstice 5 mm long covered with lax interpistillar staminodes, distally attenuate to c. 2 mm diam.; male zone obconic, distally c. 4 mm diam.; stamens large, c. 1.3 mm across, truncate, apparently connate, with the dome-like apices of the thecae elevated above the connective and opening through very conspicuous, large apical pores c. 0.6 mm diam.; appendix more or less hemispheric; staminodes irregularly polygonal with sharp angles and flat tops, c. 0.8 mm diam. Fruiting spathe narrowly urceolate, c. 3 cm long.
