[Plant form] The stalk is 8 to 10 meters high. The tail tip is bent down and the lower part is straight. It is green, and when it is young, it is saponified with white wax powder. The light brown bristles that are adhering or sparse or dense are later changed into hairless; the joints are flat. Hairless; Branches often start from the middle and lower section of the culm from the seventh to the eleventh, and are clustered on several branches and even multiple branches. The central branch is slightly thicker and longer. Sheath sheath caducous; leathery, apically broadly arched with an asymmetric wide arch, small scallops, large ears narrowly oblong to lanceolate; scallops at the edge of tongue; bracts erect, ovate Narrow triangular; leaf sheaths glabrous, with ridges on back; leaf ears often sickle-shaped; ligule very low, margin erosive, glabrous; leaf blade linear-lanceolate to narrowly lanceolate, glabrous above, densely below Pubescent, apex attenuate with sharp, pointed tips, base suborbicular or cuneate. Fake spikelets solitary or clustered in squid sections, dark purple when fresh, bronze when dry, linear-lanceolate; leaves broadly ovate, with 2 ridges; buds sepals 2 or 3, broad Ovary; spikelets with 5-8 flowerlets; rachis internodes are semi-cylindrical or flat, tip apical; glaucous, broadly ovate, with 21 veins; ankle elliptic, with 25 veins; Lanceolate, with 2 ridges, 20 veins between ridges; scales unequal, margin ciliate long; filaments slender, anthers yellow; ovary broadly ovoid, style shortly hirsute, stigma 3.
