    General Description

    Tuber discoid to globose, ca. 6.5 cm in diam., ca. 3 cm high, seasonally producing up to 5 rhizomatous offsets, these whitish, 6-47 cm long, basally 6-8 mm in diam., apically 9-14 mm in diam., internodes 20-44 mm long, apically 1-3 more tuber-like internodes of 12-23 x 19-44 mm. Leaf solitary, developing after flowering in the same season, petiole 40-55 cm high, 9-18 mm in diam., smooth, pale green, densely set with whitish, more or less longitudinal blotches; lamina 42-57 cm wide, rachises distinctly winged distal from the basal branching points; leaflets lanceolate, smaller ones 3.8-7 x 1.2-2 cm, largest ones 15-20.5 x 3.8-5.5 cm, long-acuminate, adaxially dark green, abaxially paler. Inflorescence solitary, developing before the leaf; peduncle 37 cm long, 8-10 mm in diam., sal11e colour pattern as petiole. Spathe erect, lanceolate, 16.5 cm long, 3.8 cm wide, base and limb not sharply differentiated, limb ca. 2 cm wide, apically acute, outside upper third bronze-coloured with a darker reticulate pattern, more basally a much brighter, almost whitish zone of ca. 1.5 cm which diverges to the basal margins, base inside opposite the fertile part dark purplish brown, here shallowly ridged and verrucose, outside in the upper parts same colour as on the inside, but basally greenish. Spadix longer than spathe, 25 cm long; female zone cylindrical 8-10 mm long, ca. 10 mm in diam., flowers slightly distant; male zone cylindrical 20-23 mm long and 7-10 mm in diam., flowers congested; appendix cylindrical, tapering, basally ± grooved, 20.5 cm long, ca. 6-10 mm in diameter, yellowish violet, with a whitish wah)' coating, producing a faint putrid smell. Ovaries ± ovate, l.5-l.6 mm in diam., 1.5-1.8 mm high, tapering to the style, obliquely inserted, with the stigmas projecting upward, pale green, apically brownish violet, unilocular; style ca, 0.2 mm long, brownish-violet; stigma discoid-convex, 1.3-1.5 mm in diam. occasionally grooved in the middle, surface sparsely tuberculate, brightly yellow-orange. Male flowers consisting of (1-)2-3(-4) stamens, in the lower part of the inflorescence sometimes connate; filaments basally fused, anthers rectangular in top view, truncate, ca. 1.5-2.2 X 1.3-1.7 mm, ivory coloured, connective and the pores purplish, connective broad, depressed in the middle, pores ellipsoid, apical. Pollen inaperturate, exine psilate, globular ± elliptic to slightly reniform when dry, 35-50 x 30-40 micron. Berries elongate, 1-1.5 cm long and ca. 0.7 cm in diameter, red; seeds elongate, ca. 0.9-1.3 cm long, ca. 0.5 cm in diameter.
