==辨析==
This species is taken here in a broad sense to include all slender, narrow-leaved specimens from S China and Indochina with a flat, grooved, winged sessile spikelet and a swollen lowermost pedicel. The differences from Cymbopogon caesius (Nees ex Hooker & Arnott) Stapf, from E Africa to India, are very slight. Cymbopogon caesius tends to have a longer ligule, to 4 mm, and paler inflorescences. Likewise, C. annamensis hardly differs from C. mekongensis, except in the swollen lowermost pedicel.
本种花费在这里在广义上包括全部纤细, 来自Cymbopogon caesius(尼斯前用钩的人和阿诺特)Stapf的差别,从非洲东部到印度,非常轻微。 Cymbopogon caesius倾向于有一长叶舌,对4毫米和浅的花序。 同样,除了在膨胀的最下的花梗里,C. annamensis几乎不不同于C. mekongensis。
