L. chinensis is a strongly tufted,

L. chinensis is a strongly tufted, annual or short-lived perennial grass with glabrous leaves and fibrous roots. Its flowering culms are erect or ascending from a branching base. They are occasionally stoloniferous and 0.3-1.2 m tall. They have 3-6 nodes which have glabrous internodes that are smooth, grooved and striate and hollow. The leaf sheaths are keeled, glabrous, smooth, not ciliate, distinctly nerved and usually longer than the associated internodes. The leaf blade is linear, acute, membraneous, green and slightly glaucous. It is 6-32 cm long, 4-9 mm wide, flat or folded, glabrous and rough on the upper surface.The ligules are 1-2 mm long with setaceous hairs on the adaxial surface. They are deeply divided into hairlike segments and erose.

The inflorescence forms an open panicle 15-60 cm long, with numerous, slender, flexuous branches. Axis is 10-40 cm long, grooved and scabrous with glabrous axils. The panicle has ascending primary branches which are slender and not winged. They are 2-13 cm long, distinctly grooved and bear spikelets to the base. The pedicels are 0.4-1 mm long and minutely scabrous on the margins.

The spikelets have between 3 and 7 flowers but usually 5-6 flowers are present. These are 2.0-3.5 mm long, 0.8-1.3 mm wide and are often purplish and appressed to the primary branches. The rachilla is filiform and glabrous with similar florets which are perfect, reduced upwards and overlapping.

The glumes are shorter than the lemmas. The first glume is usually shorter than the second. It is has a single nerve and is 0.6-1.5 mm long. It is hyaline to membraneous but scabrous on the nerve and lanceolate. The apex is acuminate. The second glume is 0.9-2.4 mm long and 3-nerved. It is keeled and otherwise similar to the lower glume. Disarticulation occurs above the glumes and between the florets.

L. chinensis adalah sangat berumbai, tahunan atau pendek rumput abadi dengan glabrous daun dan akar fibrous. Culms berbunga yang tegak atau naik dari basis bercabang. Mereka kadang-kadang stoloniferous dan 0.3-1.2 m tinggi. Mereka memiliki 3-6 node yang memiliki internodes glabrous yang halus, beralur dan striate dan berongga. Selubung daun keeled, glabrous, halus, tidak ciliate, jelas nerved dan biasanya lebih dari internodes terkait. Pisau daun linear, akut, membraneous, hijau, dan sedikit hijau keabu-abuan. Itu adalah 6-32 cm panjang, 4-9 mm lebar, datar atau dilipat, glabrous dan kasar pada permukaan atas.Ligules adalah 1-2 mm panjang dengan bulu-bulu yang setaceous di permukaan adaxial. Mereka sangat dibagi menjadi segmen-segmen hairlike dan erose.Perbungaan Malai terbuka membentuk 15-60 cm panjang, dengan banyak, cabang-cabang yang ramping, flexuous. AXIS merupakan 10-40 cm panjang, beralur dan scabrous dengan glabrous axils. Malai telah mendaki cabang utama yang ramping dan tidak bersayap. Mereka 2-13 cm panjang, jelas beralur dan menanggung spikelets ke dasar. Pedicels adalah 0.4-1 mm panjang dan teliti scabrous di pinggiran.Spikelets memiliki antara 3 dan 7 bunga tetapi biasanya bunga 5-6 hadir. Ini adalah 2.0-3.5 mm panjang, 0,8-1.3 mm lebar dan keunguan dan appressed cabang-cabang utama. Rachilla filiform dan glabrous dengan kelopak bunga serupa yang sempurna, ke atas berkurang dan tumpang tindih.Glumes lebih pendek dari lemmas. Pemeliharaan pertama biasanya lebih pendek daripada yang kedua. Memiliki satu saraf dan 0,6-1.5 mm panjang. Ianya hialin membraneous tapi scabrous di saraf dan ellips. Puncak acuminate. Pemeliharaan kedua adalah 0,9-2.4 mm panjang dan 3-nerved. Ini keeled dan sebaliknya mirip dengan pemeliharaan rendah. Disarticulation terjadi di atas glumes dan antara kelopak bunga.
