SUMMARY
Herb c. 11-40 cm tall. Stem condensed, more or less epigeal, 1-2 cm diam., pleionanthic. Leaves several together, crowded; petiole 5-30 cm long, sheathing in the lower c. ?; wings of sheath fully attached, narrow, tapering; blade lanceolate to narrowly elliptic and then somewhat rhomboid, 7-21 cm long × 1.5-6 cm wide, the base acute to obtuse and then shortly decurrent, the apex acute and acuminate for 1-3 cm; midrib abaxially somewhat prominent, with 5-9 primary lateral veins on each side, alternating with lesser interprimaries and diverging at 30-45°; secondary venation adaxially obscure, arising from the midrib; tertiary venation obscure. Inflorescence solitary or two together, produced severally in close sequence alternating with foliage leaves; peduncle 3-12 cm long, subtended by very narrowly lanceolate persistent/marcescent cataphylls 4-16 cm long. Spathe 3-5.5 cm long, subcylindric; lower spathe 1-1.5 cm long, narrowly ovoid, differentiated from the limb by a weak constriction; limb more or less lanceolate, 2-4 cm long, slightly inflated over the appendix and thence acuminate for 0.8-1 cm, ?caducous. Spadix sessile, 2.5-4 cm long, subcylindric; female zone 0.8-1.5 cm long, adnate to the spathe in the lower 1/2?, the free part narrowly conic and apically 1.5-2 mm thick corresponding with the spathe constriction; pistils crowded, subglobose, 0.4-0.6 mm diam.; stigma button-like, about half the diameter of the ovary, elevated on a very short style; interpistillar staminodes very few or none among the pistils otherwise confined to an irregular row along the spathe/spadix adnation, shortly stipitate, flat-topped, about the height and diameter of the pistils; sterile interstice well-defined, about 3 mm long, slightly and abruptly thicker than the top of the female zone, 1.5-3 mm diam., 4-5 compacted whorls of flat- topped sterile stamens c. 1 mm across and drying dark brown; male zone more or less cylindric, 0.7-1 cm long × 2-3 mm thick; stamens crowded, truncate, strongly dumbbell-shaped, c. 1 mm across, the connective not raised above the thecae, but the thecae with a narrow raised rim; pores slit-like, C-shaped; appendix 1-1.8 cm long, cylindric, blunt-tipped, the base slightly and abruptly thicker than the male zone, c. 3-4 mm diam.; staminodes of appendix flat-topped and somewhat impressed centrally, c. 0.6 mm diam. Fruiting peduncle not much elongated; fruiting spathe urceolate, c. 1-1.5 cm long.
