Hackelochloa GRAMINEAE Capillipediuin 



spikelets awnless, in pairs; the rachis joint and pedicel adnate, clasped between the 

 edges of the globose alveolate first glume of the sessile spikelet; pedicelled spikelet 

 conspicuous, staminate; 2 species; 1 in China. (After Prof . Eduard Hackel, 1850-1926, 

 noted Austrian agrostologist.) 



1. Hackelochloa granulans (L.) Ktze. (Hitch. 788). Annual, coarsely hispid; culms 

 3-10 dm. high; fls. X, racemes terminal and axillary, 1-2 cm. long; fr. X-XI. 

 Most tropical countries; locally in An. Grassy slopes. 



83. Eremochloa Buse ^fefM (Wu Kung Ts'ao Shu) 



Slender perennials with solitary compressed spike-like racemes: spikelets solitary 

 at each node; the pedicelled ones reduced to glume-like or stipiform structures; 

 sessile spikelets dorsally compressed, awnless, imbricate along one side of, but not 

 sunken in the slender jointed rachis. About 10 species, in tropical and temperate 

 Asia; 3 in China. (Greek: eremo, desert, and chloa, grass, alluding to the habitat of 

 the type species, E. horneri Buse.) 



1. Eremochloa ophiuroides Hack. ©jfe^pC (Wu Kung Ts'ao; Centipede Grass) (Hitch. 

 787). Culms stoloniferous, 15-30 cm. high; fls. and fr. VII-IX. Southeastern 

 China to Formosa; locally in An., Che., Ki., Ku. Moist grassland. 



84. Bothriochloa Ktze. l\Jf$M% (K'ung Wen Ts'ao Shu; 

 Pit-marked-grass Genus) 



Perennials with {paniculate to) corymbose- digitate racemes: spikelets binate; the 

 sessile perfect, owned; the pedicelled staminate, awnless: rachis joints and pedicels 

 slender, longitudinally grooved between the thickened margins. About 25 species, 

 mostly in tropical Asia; 3 in China. (Greek: bothros, a pit, and chloa, grass, alluding 

 to the pitted first glumes of the type species, B. anamitica Ktze.) 



1. Bothriochloa ischaemum (L.) Keng (Andropogon ischaemum Linn.) (H.F. 7: 171). 

 Culms 30-90 cm. high; fls. and fr. V-X. Tropical and temperate Asia; locally in 

 An., Ku. Grassy slopes and waste places. Fig. 451. 



85. Capillipedium Stapf #B$J^M (Hsi Ping Ts'ao Shu; 

 Slender-pedicel-grass Genus) 



Perennials with open panicles of 1-5 (rarely up to 8) jointed racemes: spikelets 

 binate, or ternate at the terminal joint of the rachis: joints and pedicels filiform, 

 longitudinally grooved. 6 species, in tropical and temperate zones of the Old World; 

 2 in China. (Latin: capillus, a hair, and pes {pedis), a foot, alluding to the filiform 

 pedicels.) 



Key to the Species 



Culms erect, simple or sparingly branched; the brs. appressed to the 

 culm: blades linear, not glaucous: pedicelled spikelets mostly 

 similar to or smaller than the sessile ones 1 . C. parviflorum 



Culms more or less decumbent at the base, freely brg.; the brs. spread- 

 ing widely from the culm: blades sublanceolate, glaucous: pedi-
