Spodiopogon GRAMINEAE Pogonatherum 



Culms 0.7-1.5 m. high; fls. VIII; fr. IX. Temperate Asia; locally in An., Che., 

 Ki., Ku. Grassy hills and shady thickets. 

 2. Spodiopogon cotulifer (Thunb.) Hack. $£ (Yu Mang; Oily-awn) (L.SJ.7:235).

74. Eulalia Kunth ^k^M (Chin Mao Shu; Golden-grass Genus) 



Perennials (ours) with two to several digitate or approximate racemes: spikelets 

 binate; one sessile, the other pedicelled; all alike and perfect, on an articulate rachis, 

 usually awned from the dilated base of the upper lemma. About 25 species, in 

 tropical and temperate parts of the Old World; 6 in China. (Named for Eulalie 

 Delile, wife of A.R. Delile (1788-1850), professor of botany at Montpellier, France. 

 She made the drawings for Kunth's " Distribution methodique de la famille des 

 Graminees," 1835.) 



Key to the Species 

 Basal sheaths of the culm woolly at the base with yellowish-brown 



hairs 1. E. speciosa 



Basal sheaths of the culm glabrous at the base 2. E. quadrinervis 



1. Eulalia speciosa (Debeaux) Ktze. (L.S.J. 7:233). Culms 0.8-1.7 m. high; fls. VII; 

 fr. VIII. Northern India to eastern Asia; locally in An., Che., Ki., Ku. Dry 

 slopes and grassy hills. Fig. 446. 



2. Eulalia quadrinervis (Hack.) Ktze. (L.SJ.7:233). Culms 30-100 cm. high; fls. X; 

 fr. XI. India to eastern Asia and the Philippines; locally in Che., Ku. Dry 

 slopes and grassy hills. 



75. Microstegium Nees 'Mj^HI (Hsiao Pao Ts'ao Shu) 



Resembling Eulalia in the digitate racemes and in the binate spikelets, but 

 differing in the straggling habit with lanceolate or ovate-lanceolate blades. About 30 

 species, in tropical and temperate parts of the Old World; 6 in China. (Greek: 

 micros, small, and stege, a roof or covering, alluding to the lemmas being shorter 

 than the glumes.) 



Key to the Species 



Spikelets 4-6 mm. long; the awns twisted, 5-8 mm. long, or sometimes 



wanting 1 • M. vimineum 



Spikelets 3-4 mm. long; the awns capillary, 10-15 mm. long 2. M. nudum 



1. Microstegium vimineum (Trin.) A. Camus (Hitch.748). Culms 0.5-1.0 m. high; 

 fls. IX; fr. X. Northern India to eastern Asia and the Philippines; locally in 

 An., Che., Ku. Moist or shady ground. 



2. Microstegium nudum (Trin.) A. Camus (L.S.J. 7:233). Culms 20-60 cm. high; 

 fls. IX; fr. X. India to eastern Asia and Malaysia; locally in Che., Ku. Moist 

 or shady ground. Fig. 447. 



76. Pogonatherum Beauv. &MMM (Chin Fa Ts'ao Shu) 



Rather low and slender perennials with terminal solitary spike like racemes: 

 spikelets binate; one sessile and perfect; the other (smaller) pedicelled and pistillate; 

 both 2-awned, imbricate on slender jointed rachis. Three species, in tropical or
