SUMMARY
Moderately robust herb to c. 45 cm tall. Stem condensed, more or less hypogeal (?becoming epigeal), c. 1.5 cm diam., pleionanthic. Leaves c. 5 together; petiole c. 37 cm long, sheathing in the lower quarter; wings of sheath fully attached to the petiole, tapering; blade ovato-sagittate, 19–26 cm long × 11–18 cm wide, the base cordate with somewhat angularly rounded posterior lobes to c. 7 cm long, the tip acute and rather abruptly acuminate for c. 1 cm; midrib not prominent abaxially (dry), with c. 7 primary lateral veins on each side, alternating with lesser interprimaries and
diverging at c. 45–70°; secondary venation more or less obscure on both surfaces, mostly arising from the midrib, some from the lower parts of the primary veins; tertiary venation obscure. Inflorescence ?solitary but to 3 in succession interspersed with foliage leaves [organisation not clear from available material]; peduncle not or hardly exserted from the subtending leaf bases and cataphylls; cataphylls lanceolate, to c. 4 cm long. Spathe 5–6 cm long; lower spathe more or less flask-shaped — rather broadly ovoid at the base, narrower and subcylindric in the upper part, c. 2–2.5 cm long, not constricted at interface with the spathe limb; limb oblong-lanceolate, 3–4 cm
long, apiculate for 3 mm, deciduous. Spadix sessile, 3.2–4.2 cm long, subcylindric; female zone obliquely inserted, c. 7 mm long, somewhat conoid, c. 4 mm diam. at top; pistils subglobose, c. 0.7 mm diam.; stigma discoid, sessile, about as wide as the ovaries, papillate; interpistillar staminodes few, scattered among the pistils, clavate, flat-topped, about twice the height of the pistils; sterile interstice ill-defined — some concentration of interpistillar staminodes and sterile stamens mixed with fertile elements at the interface of the two zones; male zone cylindric, c. 1 cm long × 3 mm
diam., almost entirely within the lower spathe chamber; stamens more or less rectangular, truncate, c. 0.5 mm across, the connective thick and block-like, pores small, more or less slit-like, distant, with pollen extruded in filaments; appendix more than half the length of the whole spadix, cylindric, basally very slightly thicker than the male zone, ultimately tapering to an obtuse point; staminodes of appendix low, flat-topped, irregularly polygonal with sharp angles, c. 0.5 mm across. Fruiting peduncle hardly lengthening; fruiting spathe urceolate, c. 2 cm long (immature).
