Description:
Herbs, corms subglobose, 4-8 cm diameter, 2.5 cm thick. Leaf trichotomously decompound with petiole cylindric, 30-75 cm long, smooth, green with dark greenish brown mottles; rachis of the segments 15-20 cm long, shallowly channeled above and with decurrent leaf bases; leaflets sessile, ovate to oblong, acuminate at apex, acute at base, base unequal and decurrent on rachis, greenish above, 6-13 x 3-6.5 cm; primary veins 15-20 pairs, closely parallel, united below the margin forming an intramarginal vein. Stolons cylindric, 4-5 x 0.4-0.7 cm, nodes with thin scale leaves and few root primordia. Inflorescence with peduncle, 30-75 cm high, 1-1.6 cm diameter at base, gradually narrowly to the tip; spathe ovate-oblong, 12-22 cm long, differentiated into a basal convolute tube and an upper expanded limb with a shallow constriction in between, tip shortly acuminate, 2.5-3.5 cm diameter at convolute base, 2-3 cm diameter at the constriction, and 3-3.5 cm diameter just above the constriction. Spadix stipitate, 9-18 cm long; stipe to 0.5-1 x 0.5-0.6 cm, light greenish; basal portion of 2-3.5 cm of the spadix occupied with pistillate flower, middle 1-1.5 cm with neuter flowers, upper 3-3.5 cm with staminate flowers, and terminal 4.5-10 cm produced into a sterile cylindric barren appendix; a barren naked zone of 0.2-0.3 cm between the zones with pistillate and with neuter flowers. Pistillate flowers subspirally arranged; ovary sessile, subglobose, 0.18-0.2 x 0.2-0.3 cm, greenish, 2- or 3 loculed, each with one subbasal ovule; style very short, cylindric, 0.5-0.8 x 0.8-1 mm; stigma 2 or 3-lobed, covered with short unicellular papillae; neuter flowers in 1-3 rows, creamy white, obovoid, 0.2-0.3 cm diameter, few appear to be transitional to the staminate flowers. Staminate flowers closely arranged, each compressed of 2-5 stamens borne on a white cushion-like tissue of 0.8-1 mm thickness; stamen 0.1-0.13 cm high, inconspicuously 2-lobed; thecae dehisce by narrow apical horizontal slits. Spadix-appendix cylindric, 4.5-10 x 0.8-1 cm, rounded at apex, cream in colour, smooth except rarely at the.
