Rhizomes creeping, branched, flexible, reddish brown to white. Roots solitary at each node, branched. Internodes upto 1.5 cm long, often swollen at nodes. Shoots upto 70 cm long, erect, unbranched, rarely branched, bearing 2-5 leaves at each branch. Leaf sheaths broadly triangular or obconical, transparent, margins entire and folded inwards, clasping the stem, pink to pale brown.
Male flowers solitary, terminal at first and pushed laterally by the successive lateral shoots, borne on the tip of two different adjacent nodes giving the appearance of 2 flowers in the same node. One flower ca 4.3 cm long; stalks ca 3.5 c long, flattened, rigid, erect, brown with dehisced anthers. Another flower enclosed in reduced leaves and spathes. Spathes 1 or 2, obconical, subtruncate at base, truncate to obtuse at apex, convolute, entire along margins, transparent with many vertical tannin dashes. Anthers 2, linear-elliptic with slightly bent subular appendages at base and straight at apex, dorsally connate and equally attached to the stalks with numerous reddish brown tannin dashes, dehiscing longitudinally. Female flowers in pairs, sessile or minutely stalked, brown. Ovaries subglobose. Style 1, forked, slender, laterally compressed, brown. Stigmata equal or subequal, bent downward, brown.
Fruits 2, ellipsoid, 4-angular, sessile or minutely stalked, ridged, green when young, brown when mature, rarely 1 undeveloped fruit seen adjacent to 1 matured fruit. Beak apical, slightly bent, rarely with remnants of style. Exocarp sclerenchymatous, brown. Seeds oblongoid, white to yellow. Radical red or with orange tinge.
