Miscanthus sacchariflorus is a perennial plant and forms long, slender rhizomes that are covered with short, bald to hairy cataphylls . The stalks are slender, upright, 65 to 160 cm high, not hollow and unbranched. The leaves are on the stalk. The leaf sheaths are grooved and glabrous. The leaf blades are linear, flat, 20 to 50 cm long and 0.5 to 1.5 cm wide. They are bald, have a distinct midrib and taper to a point. The ligule is around 5 mm long and has eyelashes 1 to 2 mm long.
The inflorescence is a 7 to 30 cm long panicle , the main axis of which is 5 to 15 cm long, glabrous or hairy at the base. The four to 24 racemose partial inflorescences are 5 to 20 cm long. The internodes of the rachis are bare, the nodes bare or hairy. The spikelets are 4 to 6 mm long, hairy and not awned. 8 to 12 mm long hairs that protrude from the spikelet sit on the callus. The glumes are heterogeneous, membranous, 4 to 6 mm long, with indistinct nerves and pointed at the end. The lower glume is hairy with long hairs on the edges. The upper one has only short hairs at the tip. The lemmas are lanceolate, hyaline and around 3 mm long. They have 0 to 1 nerves, the tip and edges are hairy. The palea is formed as a small, nerveless, hairy scale. The three anthers are 2 to 2.5 mm long. The caryopsis is elongated.
