  多年生。秆细弱，不分枝或自基部分枝，基部节上生根而伏卧，高约40厘米，节处略膨大，微有细柔毛，节间无毛。叶鞘通常略长于节间，松弛裹茎，除边缘具纤毛外其余无毛；叶舌纤毛状，长约2毫米；叶片线状披针形，长5-9厘米，宽6-8毫米，顶端渐尖，基部钝圆，上面无毛，下面具微细毛而粗糙，边缘稍增厚而为软骨质。圆锥花序抽出叶鞘外，卵形，长7-10厘米，宽3-5厘米，每节具1-2个分枝，分枝纤细稍蛇曲，斜升，下部裸露，上部着生小穗，主轴、分枝和小穗柄无毛，但具黄色腺斑；小穗椭圆形，淡绿色，长1.5-1.8毫米；两颖略长于小穗，卵状椭圆形，顶端尖或骤尖，背部在中部以上被微细的小硬毛，具不明显的7-9脉；两小花同质同形，均为两性，或第二小花有时可为雄性；稃体软骨质，无毛。颖果椭圆形，棕色，长约1.2毫米。花果期秋季。
  产福建、广西等省区；生于山谷肥沃土壤上。模式标本采自广西临桂县。
  我国一些禾草学者曾将本新种误定为 lsachne kunthana（Wight et Arn.） Miq. 经作者对采自印度马达拉斯（Madras; J. S. Gamble no. 12409）和斯里兰卡（Ceylon; Ballard no．1214）的该种标本与我国产本种标本进行比较，证明两者决非同物。lsachne kunthiana（Wight et Arn.）Miq. 的叶片为卵状披针形，基部心形，两面均被疣基柔毛，尤以背面较密；花序分枝粗而短，通常贴向穗轴，花序较紧密，分枝与小穗柄均无腺斑，颖片顶端尖，长于小穗1/4-1/3，且小穗也明显较本种为大。

Isachne guangxiensis  W. Z. Fang
广西柳叶箬   guang xi liu ye ruo
Isachne albens Trinius var. glandulifera P. C. Keng.
Perennial. Culms slender, branching and rooting at lower nodes, ca. 40 cm tall, nodes slightly swollen, puberulous. Leaf sheaths loose, slightly longer to slightly shorter than internodes, glabrous except for ciliate outer margin; leaf blades linear-lanceolate, 5–9 × 0.6–0.8 cm, abaxial surface puberulous, adaxial surface glabrous, margins slightly thickened, base subrounded, apex acuminate; ligule ca. 2 mm. Panicle open, ovate in outline, 6–10 cm, glandular; branches 1–2 per node, scaberulous, lower part naked, pedicels slender, equaling or longer than spikelets. Spikelets elliptic, 1.5–1.9 mm, yellowish green; florets similar, lower male or bisexual, upper bisexual; glumes ovate-elliptic, equaling or slightly longer than florets, hirtellous above middle, obscurely 7–9-veined, acute; lemmas subleathery, glabrous. Fl. and fr. autumn.

Isachne hirsuta (J. D. Hooker) P. C. Keng var. angusta W. Z. Fang (Acta Phytotax. Sin. 22: 308. 1984), described from Hunan, and I. hirsuta var. yongxiouensis W. Z. Fang (loc. cit.), described from Jiangxi, appear to match this species except that they have hairy leaves. The types have not been seen. They are excluded from I. sylvestris (of which I. hirsuta is a synonym) because they lack the glandular, nodal ring found in that species, and also the leaf blades are smaller.
