Beechey Voy. 244. 1838. Cymbopogon hamatulus Hook. Arn. A. Camus. Rev. Bot. Appl. Agric. Colon. 1: 284. 1921. Cymbopogon jinshaensis R.S. Chang C.H. Li. J. Pl. Res. Environm. 22: 39. 1993. Plants perennial, caespitose. Culms 70-100 cm long, erect. Nodes glabrous; internodes distally glabrous. Sheaths glabrous on surface. Ligule an eciliate membrane. Blades 25-60 cm by 4-5 mm, aromatic, the surface glabrous. Inflorescence: Synflorescence compound, scanty, or linear, 35 cm long. Inflorescence composed of racemes, terminal and axillary, subtended by a spatheole. Spatheole 1.4 cm long, elliptic. Racemes 2, paired, 1.3 cm long, deflexed. Rachis fragile at the nodes, semiterete, glabrous on surface, ciliate on margins, internodes linear. Raceme- bases flattened, unequal. Spikelets in pairs: fertile spikelets sessile, 1 in the cluster; companion sterile spikelets pedicelled, 1 in the cluster. Pedicels linear, semiterete, ciliate. Fertile spikelets comprising 1 basal sterile florets, 1 fertile florets, without rachilla extension, lanceolate, dorsally compressed, 4 mm long, falling entire, callus base obtuse, inserted. Sterile spikelets: basal sterile spikelets well-developed, 2 in number lower raceme, 0 in upper raceme, with normal internodes, sessile and pedicelled; pedicels free, linear; basal male, equalling fertile; lower glume muticuous. Companion sterile spikelets well-developed, male, 3 mm long, lanceolate, shorter than fertile, deciduous with the fertile; glumes chartaceous, 7-nerved, acute, muticuous; lemmas 2, enclosed by glumes. Glumes dissimilar, exceeding apex of florets, firmer than fertile lemma. Lower glume as long as of spikelets, lanceolate, chartaceous, 2- keeled laterally, winged narrowly; intercarinal nerves distinct, 3-4 in number; surface flat. Upper glume lanceolate, 1-keeled above, apex acute. Florets: basal sterile florets barren, without significant palea; lemma hyaline. Fertile lemma lanceolate, hyaline, without keel; apex lobed, bifid, 1-awned; principal awn from a sinus, 8 mm long, geniculate, with twisted column. Palea absent or minute. Anthers 3. Notes Found in China, Eastern Asia, Indo-China, and Malesia. Useful for erosion control. Distribution at Sulawesi North: Gorontalo. Habitat Found in open areas, open fields.
