多年生草本。具匍匐茎。秆纤细，高5-10厘米。叶鞘无毛，紧密裹茎；叶舌膜质，长约0.3毫米，顶端碎裂为纤毛状，鞘口具丝状长毛；小穗窄狭，黄绿色，或有时略带紫色，长约3毫米，宽约0.6毫米，披针形；第一颖退化，第二颖革质，顶端及边缘膜质，具不明显的5脉；外稃与第二颖近等长，具1脉，内稃退化；无鳞被；花药长约0.8毫米，花柱2，柱头帚状。颖果与稃体分离。染色体2n=40（Chen et Hsu，1962）。花果期8-12月。
产我国南部地区，其他地区亦有引种栽培。分布于热带亚洲，现欧美各国已普遍引种。是铺建草坪的优良禾草，因草质柔软，尤宜铺建儿童公园。模式标本采自马斯卡林群岛。

Zoysia pacifica (Goudswaard) M. Hotta & S. Kuroki
细叶结缕草 xi ye jie lü cao
Zoysia matrella (Linnaeus) Merrill var. pacifica Goudswaard, Blumea 26: 172. 1980.
Perennial, stoloniferous, forming a low dense sward. Culms 5–10 cm tall, much branched. Leaf sheaths glabrous, bearded at mouth with 2–5 mm hairs; leaf blades setaceous, soft, 4–6 cm, ca. 1 mm wide. Inflorescence linear, up to 1.5 cm; spikelets 6–12, loosely overlapping; rachis somewhat wavy; pedicels shorter than spikelet, up to 1.6 mm, scabrous, slightly widened at apex. Spikelets 2–3 × ca. 0.6 mm, straw colored tinged purplish; lower glume absent; upper glume lanceolate, shiny, obscurely 5-veined, apex subacute, sometimes with subapical awn-point; lemma slightly shorter than upper glume, 1-veined; palea absent. Anthers 0.6–0.8 mm. Fl. and fr. Aug–Dec. 2n = 40*.
Rocky and coral beaches. Taiwan [Japan (S Kyushu and Ryukyu Islands), Philippines, Thailand; Pacific Islands].
This grass has been widely known as Zoysia tenuifolia Thiele, but the type specimens of that name belong taxonomically to Z. matrella.
This fine-leaved, densely growing, low grass forms excellent lawns and is grown in gardens in S and SE China.
