Schrk.). Spikelets very small, elliptical, naked; third 

 glume usually awned ; disposed 

 in somewhat compact panicles. 



Species one (M. minutiflora 

 Beau v.), in Brazil, Ascension, 

 Natal, Madagascar. In Brazil 

 it is called " Capimmellado" on 

 account of its glutinous proper- 

 ties. It is prized for fodder and 

 is even cultivated. 



51. (52) Phaenosperma Munro. 

 Panicles large, branches in 

 whorls ; caryopsis projecting 

 from the glumes half its length. 



Species one (Ph. globosa), in 

 China. 



52. (54) Triscenia Griseb. A 

 grass of doubtful relationship, 

 on account of the small embryo, 

 having nearly the same habit as 

 Festuca ovina. Panicles few- 

 flowered. Spikelets one-flow- 

 ered. 



Species one ( T. ovina Gri- „ 



L v Fig. 2S.—ArundineUa Nepalensts

53. (55) Arthropogon Nees. 



Panicles loose. Empty glumes coriaceous, the second 

 largest. One $ flower in the axil of the third glume. 

 Species two ; one in Brazil, the other in Cuba. 



54. (58) Thysanolsena Nees (Mijriochvto Zoll.). Pani- 

 cles very large, with innumerable minute spikelets in 

 short racemes. Spikelets as in Panicum, but the flowering 

 glume is delicate and fringed with hairs. 



Species one (Th. acarifera Nees), "Tiger Grass," in 

 tropical Asia — a troublesome weed among cultivated 

 plants ; 2-4 m. in height. 



55. (47) Beckera Fresen. Spikelets in numerous 

 spikes in the axils of the leaves. Third empty glume 

 with a long straight awn, flowering glume awnless or
