 Natal, Madagascar. In Brazil 

 it is called " Capimmellado" on 

 account of its glutinous proper-

 is even cultivated. 



51. (52) Phsenosperma 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- 



, x r . _. , FIG. 23. Arundtnella Nepalensts

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



54. (58) Thysanolaena Nees ( Myriachceta 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 (Tk. 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
