SUMMARY
Herb c. 45 cm tall. Stem condensed, epigeal, rooting among the leaf bases, ?pleionanthic. Leaves few (c. 4) together; petiole c. 18 cm long, sheathing in the lower ⅓, narrowly alate; wings of sheath fully attached, persistent, tapering; blade thinly membranous (dry), broadly oblanceolate c. 23 cm long × 9 cm wide, the base narrowly acute and decurrent, the tip broadly acute and rather abruptly acuminate for c. 2 cm; midrib flush with the lamina with c. 17 primary lateral veins on each side, alternating with fine interprimaries and diverging at c. 60°; secondary venation arising mostly from the midrib, some from the bases of the lower primary veins; tertiary venation obscure. Inflorescences 3 together clustered low among the leaf bases; peduncle very short, completely concealed by the subtending leaf bases and cataphylls at anthesis, becoming slightly exserted (on one side) and c. 4 cm long afterwards. Spathe c. 5 cm long; lower spathe c. 1.5 cm long, ovoid, differentiated from the limb by a weak constriction; limb lanceolate, c. 3.5 cm long, apically mucronate for 5 mm, mode of deciduousness not observed. Spadix ?sessile, c. 4.5 cm long; female zone 1 cm (?or more) long, ?not adnate to the spathe, subcylindric; pistils crowded, subglobose and somewhat flat-topped, c. 0.5 mm diam.; stigmas small, slightly raised, button-like, c. 0.2 mm diam.; interpistillar staminodes absent from among the pistils (base of female zone, where they might be predicted, unobservable); sterile interstice naked except for 3 irregular whorls of abortive stamens contiguous with base of male zone, 6 mm long × 2 mm diam., level with the spathe constriction; male zone narrowly obconoid, 1 cm long, distally 3 mm diam.; stamens crowded, truncate and flat-topped, c. 0.5 mm across, dumbbell-shaped with the connective rather thick; pores of thecae flanged and cleft on the outer side; appendix 1.2 cm long, subcylindric, distally tapering to a blunt point, the base slightly and abruptly thicker than the top of the male zone, c. 0.5 mm diam.; staminodes of the appendix irregularly polygonal, flattopped, c. 0.4 mm diam. Fruiting spathe urceolate, c. 2 cm long.
