58. Sacciolepis Nash BMMM (Nang Ying Ts'ao Shu) 

 Annuals or perennials with dense spike-like panicles: spikelets oblong-conic, more 

 or less oblique: first glume usually small; second glume strongly many-nerved, similar 

 to the sterile lemma, but basally gibbous or dorsally saccate; fertile lemma chartaceous 

 indurate, with inrolled margins, about one-half as long as the spikelet; palea free at 

 the summit. More than 30 species, tropical and temperate, mostly Africa; 2 in 

 China. (Greek: sakkos, bag, and lepis, scale, alluding to the saccate second glume.)

 (Hitch.710). Culms 10-60 cm. high; fls. IX; fr. X. Asia and Australia; locally 

 in An., Ki., Ku. Moist or swampy places. 



59. Panicum Linn. HM (Shu Shu; Millet Genus) 



Perennials or annuals of various habit with infl. in open or contracted panicles: 

 spikelets dorsally compressed: glumes herbaceous; the first small or minute; the second 

 usually equaling the sterile lemma and similar in texture; fertile lemma chartaceous- 

 indurate, equaling or a little shorter than the spikelet. About 400 species, mostly 

 tropical and subtropical; 14 in China. (Ancient Latin name for the common millet, 

 Set aria italic a.)
