  多年生大型丛生草本，具强烈香气；根系较浅，根状茎粗短，质地硬，分蘖力强。叶鞘宽大，基部者内面呈桔红色，向外反卷，上部具脊，无毛或与叶片连接处被微毛；叶舌长2-3毫米，顶端尖，边缘具细纤毛；叶片长40-80（-100）厘米，宽1-1.5（-2.5）厘米，中脉粗壮，下部渐狭，基部窄于其叶鞘，上面具微毛，先端长渐尖，向下弯垂，侧脉平滑，边缘具锯齿状粗糙，下面粉绿色。伪圆锥花序大型，疏松，长20-50厘米，多回复合，下垂，分枝节部具毛，呈“之”字形膝曲；佛焰苞较小，长约1.5厘米；前叶脊上无毛；总状花序长1.5-2.5厘米，有3-5对小穗；小穗柄及总状花序轴边缘或背部具长1（中下部）-2（先端）毫米的柔毛。无柄小穗长约5毫米，第一颖椭圆状倒披针形，背部扁平或下凹，宽1-1.2毫米，上部具翼，边缘粗糙，脊间常具3脉或脉不明显，第二外稃具芒尖或芒长约5毫米，大多不伸出于小穗之外。有柄小穗长约5毫米，第一颖披针形，具7脉，边缘上部锯齿状粗糙。染色体2n=20，40 （Gupta，1969）。
  广东海南岛（兴隆福山）、台湾引种栽培；分布于印度、斯里兰卡、马来西亚、印度尼西亚爪哇至苏门答腊。模式标本采自斯里兰卡。
  栽培的香料植物，茎叶是提取精油香草醛（Citronellal）的原料。鲜叶含油量高，为0.6%-0.7%，精油中总香叶醇（Geraniol）含量83%-92%，价格较昂贵，品质优于亚香茅。
  本种以圆锥花序大型开展，后期下垂；无柄小穗长约5毫米，第一颖背部扁平，宽约1.2毫米，脊间常具3脉，第二外稃具长约5毫米的短芒，与邻近种亚香茅C. nardus（Linn.）Rendle有别。

Cymbopogon winterianus  Jowitt ex Bor
枫茅   feng mao
Perennial from a shallowly rooted rhizome. Culms tufted, robust, up to 2 m or more tall. Leaf sheaths glabrous, reddish inside; leaf blades relatively thin, drooping for 2/3 of their length, 40–80(–100) × 1–1.5(–2.5) cm, abaxial surface glaucous, adaxial surface light green, margins scabrid, base narrow, apex long acuminate; ligule 2–3 mm. Spathate compound panicle large, lax, up to 50 cm, much branched, main axis zig-zag, finally nodding; spatheoles reddish brown, 1.2–2.5 cm; racemes 1.5–2.5 cm; rachis internodes and pedicels softly ciliate on margins; pedicel of homogamous pair not swollen. Sessile spikelet elliptic-lanceolate, 4–5 × ca. 1 mm; lower glume flat or slightly concave, sharply 2-keeled, keels narrowly winged, 3-veined between keels; upper lemma very shortly 2-lobed, awn short or absent, not exserted from spikelet. Pedicelled spikelet 3.5–5 mm. 2n = 20, 40.
Commonly cultivated. Guangdong, Hainan, Sichuan, Yunnan [origin unknown; cultivated mainly in Indonesia].
This species, known only from cultivation, produces citronella oil of a higher quality than that from Cymbopogon nardus.
