SUMMARY
Small herb to c. 25 cm tall. Stemcondensed, hypogeal, stoloniferous, hapaxanthic, c. 5 mm diam. Leaves 4 together; petiole longer than the blades, 20-25 cm long, sheathing in the lower c. ¼; wings of sheath fully attached, tapering; blades narrowly cordato-sagittate, 12-17 cm long × 5-7 cm wide, the base shallowly cordate with spreading rounded posterior lobes c. 2 cm long, the apex acute and acuminate for c. 2 cm, finally with a more or less filamentous mucro c. 1.5 cm long; midrib slightly prominent adaxially (dry), more or less flush abaxially, with 5-7 primary lateral veins, alternating with lesser interprimaries and diverging at c. 60°; secondary venation arising mostly from the midrib in the upper half of the blade, from the primary venation and the midrib in the lower half; tertiary venation obscure. Inflorescences 1 or 2 together; peduncle not much exserted from the sheath of the subtending leaf at anthesis, elongating somewhat afterwards. Spathe 4.5 cm long; lower spathe narrowly spindle-shaped, 2 cm long, differentiated from the limb by a rather gradual constriction; limb ovate, 2.5 cm long, inflated over the appendix then acuminate for 1 cm, deciduous (almost certainly caducous). Spadix sessile, 3 cm long; female zone 1.4 cm long, 2 mm thick, subcylindric, adnate to the spathe in the lower c. ½; pistils crowded, narrowly ovoid, c. 0.3 mm diam.; stigma elevated on a short style, discoid, about the same width as the ovary; interpistillar staminodes scattered among the pistils, stalked, clavate, flat-topped, about the height of the pistils, c. 0.5 mm diam.; sterile interstice well-defined, 6 mm long, cylindric, 2 mm diam. (dry), covered in crowded staminodes, the basal ones resembling interpistillar staminodes, the distal ones resembling sterile anthers; male zone 8 mm long, obconic, distally 3 mm diam.; stamens crowded, dark purple, truncate, more or less dumbbell-shaped, with the thecae slightly elevated above the connective, c. 0.5 mm across; appendix c. 4 mm long, more or less conoid, abruptly wider at the base than the top of the male zone, 4 mm diam., the apex acute; staminodes of appendix flat-topped, irregularly polygonal to almost circular in outline, c. 0.3 mm diam. Fruiting peduncle c. 12 cm long. Fruiting spathe narrowly ovoid, 3 cm long.
