9. Agrostis nigra With. Black bent. 

 (Fig. 664.) Culms long-decumbent at base, 

 also with rather stout leafy stolons, the fertile

 the branches, the base usually partly included. 

 % — Sometimes found mixed with "South 

 German" bent (creeping bent), hence may 



be a constituent of lawns grown from imported seed; Europe.
