Leaf solitary; petiole 18-22 cm long, 3-4 mm in diam.; lamina with very short rachises resulting in a subradiate condition, 8-10 cm across, with usually 6 leaflets; leaflets elongate elliptic, 4-5 cm long, 1 cm wide, upper surface green with a distinct broad, pale grey feathering along the midrib, acute. Inflorescences up to 3 per season, appearing alongside the mature leaf, a few weeks after leaf development, each ca. 4 weeks apart; peduncle 16-22 cm long, 2-3 mm in diam.; spathe triangular-ovate, concave, fornicate, 4-5 cm long, 2.5- 3 cm wide, outside white with a pale greenish lower half, inside white, base inside very shallowly verrucate with very few warts, apex acute. Spadix longer than spathe, sessile, 7.5-8.5 cm long; female zone cylindric, 6-9 mm long, 5 mm in diam., flowers more or less congested; sterile zone above female zone naked, 2-4 mm long; male zone elongate cylindric-conic, 2- 2.5 cm long, 4 mm in diam. at the base, 3 mm in diam. at the apex, flowers mostly distant, partly arranged in a spiral; appendix myosuroid, 4.7-5 cm long, 2-2.5 mm in diam., slightly but distinctly sinusoid, surface smooth, off-white, apex sharply acute. Ovary depressed, 2-3-lobed, 2 mm in diam., 1 mm high, unilocular, dirty green with dark purple spots or almost entirely dark purple; style short, 0.5 mm long, 0.5 mm in diam., dark violet-purple; stigma depressed, 0.7 mm in diam., 0.3 mm high, with a central depression, surface verrucate, dark purple. Male flowers consisting of 1-3 stamens; filaments absent; anthers fused within one flower, 1 mm high, 2-3 mm in diam., off-white, pores apical, rounded. Fruiting part slightly elongate, berries congested; berries obovate, truncate, ca. 5 mm long, ca. 4 mm in diam. at the apex, basal part white, upper part pale green, surface striate-verrucate. Seeds globose, ca. 3 mm in diam., pale green. Pollen striate.
