SUMMARY
Herb c. 20–30 cm tall. Stem condensed, more or less epigeal, c. 1 cm diam., pleionanthic. Leaves few to c. 18 together, crowded; petiole 10–15 cm long, sheathing in the lower ⅓–½; wings of sheath fully attached, narrow, tapering; blade lanceolate to narrowly elliptic, 8–17 cm long × 1–4.5 cm wide, the base acute and slightly decurrent to rounded to occasionally emarginate, the apex acute and acuminate for c. 2 cm; midrib slightly prominent abaxially, with 3–9 primary lateral veins on each side, alternating with lesser, in varying degree conspicuous interprimaries and diverging at 45–60°; secondary venation adaxially obscure, arising from the midrib; tertiary venation obscure. Inflorescence solitary; peduncle slender, exserted, c. 3 cm long. Spathe c. 3.5 cm long; lower spathe 7–9 mm long, narrowly cylindric, differentiated from the limb by a slight constriction; limb c. 3 cm long, more or less lanceolate, white, ?caducous. Spadix sessile, subcylindric (very narrowly obconoid), c. 2.5 cm long; female zone c. 6 mm long, slender, subcylindric, adnate to the spathe in the lower ⅓; pistils subglobose, more or less crowded in the proximal ⅔, lax in the distal ⅓ of the zone, c. 0.4 mm diam. (dry); stigma small, c. 0.25 mm diam., elevated on a very short style abruptly differentiated from the top of the ovary, button-like; interpistillar staminodes absent from among the pistils, confined to an incomplete row along the spathe/spadix adnation, clavate, flat-topped, shortly stipitate, about the diameter and height of the pistils; sterile interstice c. 2 mm long, occupied by robust more or less sessile, more or less rhomboid staminodes c. 1.5 mm diam. and partially to completely connate in the distal part of the interstice; male zone 1 cm long, narrowly obconic, distally c. 3 mm diam.; stamens crowded, truncate, dumbbell-shaped, c. 1 mm across, the connective not elevated, the thecae with narrowly alate somewhat raised rims; appendix c. 5 mm long, bluntly conoid, slightly and abruptly wider at the base than the top of the male zone, c. 4 mm diam.; staminodes of appendix ivory, upward facing especially in the distal part of the appendix, columnar, elongate, c. 2 mm long × 0.3 mm diam., the tips rounded to erose. Fruiting peduncle not much elongated; fruiting spathe urceolate, c. 1 cm long.
