Cymbopogon liangshanensis L. Liu, Pl. Res. Gram. 11: 14. 1989. (Sphalmate ut "liangshanense")
多年生草本。秆疏丛生，基部裸露，具5-6节，秆节膨大，节内长约3毫米。叶鞘不明显增厚，松弛，内面黄绿色，无毛；叶舌长1-3毫米；叶片长20-30厘米，宽3-5毫米，粉绿色，平滑无毛。伪圆锥花序长约30厘米，分枝纤细；佛焰苞狭窄，先端渐尖，长约2厘米，宽约2毫米（每侧1毫米），边缘干膜质；总梗纤细，长5-15（-30）毫米，平滑无毛；总状花序细弱，长1-1.5厘米，宽1-1.5毫米，具3-4节；基部细瘦，不反折，无同性对小穗；总状花序轴节间与小穗柄长约2.5毫米，两侧边缘具长0.5-1毫米之柔毛，顶端具有齿裂的柄状附属物。无柄小穗长约4毫米，宽约0.8毫米；第一颖狭披针形，脊间上部有2-4脉，无翼，边缘微粗糙，顶端渐尖，有2齿，下部稍凹陷；第二外稃膜质，长2-3毫米，裂片间伸出细芒，芒长15毫米，近中部膝曲。有柄小穗退化，仅具第一颖，长2-3毫米，锥形。花果期7-9月。
产于四川西南部（凉山）；生于石灰岩山坡上。模式标本采自四川凉山。
本种以总状花序之基部不具同型对小穗，有柄小穗退化，甚窄小，仅具1枚颖片，秆基部裸露，不为宿存叶鞘包藏；小穗较小，长4毫米，第一颖无翼，顶端有2齿；第二外稃具长约15毫米的细芒，与本属其它各种显然有别。

Cymbopogon liangshanensis L. Liu ex S. M. Phillips & H. Peng
凉山香茅 liang shan xiang mao
Perennial. Culms solitary or in small tufts, slender, 50–110 cm tall. Leaf sheaths glabrous; leaf blades linear, glaucous, 20–30 × 0.3–0.5 cm, slightly scaberulous, glabrous, lower blades narrowed almost to midrib toward base; ligule 1.5–2.5 mm. Spathate panicle open, 30–40 cm, branches slender, laxly ascending; spatheoles narrowly lanceolate, greenish brown, 2–2.5 cm; racemes green, 1.5–1.8 cm, raceme bases linear, not deflexing; homogamous pair reduced, vestigial or often absent; rachis internodes and pedicels slenderly linear, margins ciliate with ca. 0.5 mm hairs increasing to 1.5 mm at apex, apices expanded, cupular, scarious, toothed. Sessile spikelet narrowly elliptic-oblong, 3.7–4 mm; lower glume shallowly concave below middle, sharply keeled, keels scabrid, wingless, 2–4-veined between keels above middle; upper lemma 2-lobed; awn 1.3–1.5 cm. Pedicelled spikelet narrow, 2–3 mm, reduced to the glumes, lower glume enclosing a much smaller upper glume. Fl. and fr. Jul–Sep.
* Mountain slopes. SW Sichuan.
This species resembles Andropogon in its non-deflexing racemes and the lack of an obvious homogamous spikelet pair, although this is usually present as a vestige. It is not known whether the leaves are aromatic. The enlarged, toothed, cupular tips to the raceme bases, raceme internodes, and pedicels are a distinctive character of this species.
