An important factor in the landscape of Hereroland ; the grass 

 forms dense meadows all along the great rivers where the banks are 

 not occupied by acacia wood, in belts of 150-250 m. along Okahandja 

 River. These meadows are the best indication of abundant water 

 in great depths and heavy loam soil which is so valuable for agri- 

 culture. ' Kwek gras " forms a dense close carpet, denser than turf of 

 any kind in Germany, and its stolons, which creep horizontally about 

 10 cms. below the surface, form a dense felt which cannot be disen- 

 tangled, so close is it that very few plants can compete successfully. 

 It is remarkable in that it spreads as much by seed as by its stolons. 

 When farmers break cynodon land they have to fight for years against 

 thousands of seedlings which spring up again and again ; if neglected, 

 the land goes back in a short time to cynodon meadow (Dinter in Bot. 

 Reis. in D.S.W.A. Fedde. Repert. Sp. Nov. Beiheft, Bd. iii, 1921). 



C. dactylon yields excellent sweet pasturage on abandoned land. 

 In the southern United States and in India it makes good hay, which 

 keeps sweet for years in stack. It grows very freely and to a large 

 size on cultivated land, but is most valued as a sand binder for the 

 walls of dams, etc. 



GENERAL DISTRIBUTION : S. Africa, Coast, Kalahari, and Eastern 

 Regions. In Old and New Worlds.
