Global description
Lipocarpha chinensis is a vivacious plant growing in tuft, 40-60 cm tall; culm more or less cylindrical, spikes of pale brown bracts, midrib marked brown. Wet grasslands, edges of swamps and rivers, gallery forests.
First leaf
Coleoptile glabrous not aristate. Glabrous sheath 1.8 to 3 mm long, trinerved. Leaf blade 7 to 10 mm long and 0.3 to 0.4 mm wide, trinerve.
General habit
Annual or vivacious plant, growing in tuft, 40-60 cm high.
Underground system
Fasciculate roots with some rhizomes.
Culm
Culm more or less cylindrical or triquetrous and 40-60 cm high and 1-1.5 mm thick.
Leaf
Basal leaves with tubular sheath. The blade usually measures half the length (allways shorter) of the culm, 10-40 cm long and 1-5 mm wide, plane, canaliculate or coiled, with edges and dorsal surface of the scabrid midrib, brownish sheath.
Inflorescence
Inflorescence terminal subtended by leafy involucral bracts (2-3) 2-5 cm long. Group of 5-12 spikes narrowly ovoid, conical or subglobular, obtuse at apex, 5 to 10 mm long and 4 to 5 mm wide, whitish or pale greenish.
Spikelet
Spikelet bract spatulate , oval or oblong, 1.5 to 2.7 mm long and 0.4 to 1.3 mm wide. Triangular apical portion of 1 to 2 mm, non-recurved, membranous, white or light yellow or greenish. Green central vein. Lanceolate glumes 1.2 to 2 mm long, 1 (2) stamens, trifid style.
Fruit
Grain 1 to 1.25 mm long, narrowly obovoid, obtuse trine, shortly apiculated, yellow, becoming light brown when ripe, with surface smooth to the eye but tuberculous.

Lipocarpha chinensis can be confused with L. sphacelata which is distinguished by its red or dark brown spikelet bracts and its grain with prominent beak. In addition the plant is smaller (10-24 cm).
