一年生草本。秆直立，常单生，高可达150厘米，直径约4毫米，通常光滑无毛，有时一侧具浅凹槽。叶鞘密生疣基糙毛；叶舌膜质，长约2毫米，上缘撕裂状，具纤毛；叶片线状披针形，长可达25厘米，宽约1.5厘米，先端渐尖，基部近心形，两面被糙毛。总状花序长2-3厘米，具无毛的梗；序轴节间与小穗柄紧密愈合，长约2毫米，易逐节断落，断面顶端凹陷，下端倒圆锥形，嵌入无柄小穗腹侧凹槽中。无柄小穗成熟后褐色；第一颖半球形，硬革质，背面具蜂窝状凹穴，基部与序轴连接处两侧各穿一孔；第二颖纸质，3脉；第一小花仅存膜质外稃；第二小花两性，稃膜质；雄蕊3，花药长约0.5毫米；雌蕊花柱离生；有柄小穗卵状披针形，长约3.5毫米；第一颖6脉，两侧具不等宽的翅；第二颖3脉，舟形，脊上亦具翅。花果期夏秋季。

Hackelochloa porifera (Hackel) D. Rhind
穿孔球穗草 chuan kong qiu sui cao
Manisuris porifera Hackel, Oesterr. Bot. Z. 41: 48. 1891.
Annual. Culms erect, 0.6–1.5 m tall, sparsely branched, often stilt-rooted. Leaf sheaths with rather rigid tubercle-based hairs; leaf blades linear-lanceolate, 5–25 × 0.5–1.5 cm, tuberculate-hispid on both surfaces; ligule 1–2 mm. Racemes 2–3 cm; peduncle glabrous or sparingly puberulent; rachis internodes ca. 2 mm. Sessile spikelets 2–2.5 mm, brown at maturity; lower glume obovate, ridged or honeycombed, upper part deeply honeycombed with sharp, narrow ribs, smooth and slightly narrowed toward base; upper glume papery. Pedicelled spikelet 3 mm or more, glumes winged. Fl. and fr. Jul–Nov.
Disturbed places; 100–800 m. S Yunnan [India, Myanmar, Vietnam].
