SUMMARY
Herb to ?70 cm tall. Stem epigeal, erect to decumbent, at least 20 cm long, 3 cm diam., with internodes c. 1.5 cm long, probably pleionanthic (renewal not observable on available material); petiole 40-55 cm long, sheathing in the lower ¼-?, minutely and rather sparsely pubescent; wings of sheath fully attached, tapering, ?persistent; blade narrowly triangular-sagittate, 27-34 cm long × 10-13 cm wide across the tips of the posterior lobes, the base deeply divided into two acute triangular posterior lobes 5-10 cm long, the apex acute and acuminate for c. 1 cm; midrib prominent abaxially (dry), minutely and densely pubescent abaxially especially in the distal part, with c. 11 primary lateral veins on each side, alternating with lesser but robust interprimaries and diverging at rather erratic angles between 45° and 90°, the nexus of primary veins of the posterior lobes more or less forming posterior costae; secondary venation abaxially conspicuous, arising from the midrib and from the primary veins; tertiary venation obscure. Inflorescences 2 (?or more) together; peduncle c. 10 cm long, slender. Spathe 8.5 cm long, thick and spongy; lower spathe broadly ovoid, 1.5 cm long, differentiated from the limb by an abrupt constriction; limb 7 cm long, oblong-lanceolate, apiculate for 1 cm, deciduous. Spadix c. 7 cm long, subcylindric; female zone 1 cm long, obliquely inserted, not adnate to spathe, cylindric, 2 mm thick (dry); pistils crowded, subglobose, c. 0.3 cm diam.; stigma sessile, discoid, papillate, slightly narrower than the ovary; interpistillar staminodes few among the pistils through most of the female zone, a concentration at the base of the female zone, robust, more or less globular, subsessile, c. 0.5 mm diam and slightly higher than the pistils (drying translucent yellow); interstice 8 mm long, slightly narrower than either fertile zone, mostly naked with a concentration of interpistillar staminodes at the base, distally with few increasingly distant small groups of interpistillar staminodes, apically with 2 very irregular whorls of enlarged sterile anthers c. 0.7 mm diam.; male zone cylindric 1.3 cm long, 3 mm diam. (dry); stamens crowded, truncate, weakly dumbbell-shaped (almost rectangular), with the connective thick but not or hardly exceeding the thecae, c. 0.5 mm across; appendix subcylindric-tapering, apically acute, 3 cm long, basally slightly wider than the male zone, c. 4 mm diam.; staminodes of appendix flat-topped, irregularly polygonal, c. 1 mm diam. Fruiting peduncle slightly elongating, declinate. Fruiting spathe broadly ovoid-urceolate, 4 cm long.
