AGRICULTTJEAL SPECIES OF BENT GEASSES. 13 



(8) Carpet bent (Agrostis sp. indet.) and velvet bent (Agrostis 

 canina L.) make up much of tbe turf on 3-year-old lawns grown from 

 South German mixed bent seed. This mixed seed constitutes at 

 present the only commercial supply of these two iSne bents. 



(9) Red top and fiorin produce rather coarse turf as contrasted with 

 the three fine bents. Of the latter, velvet bent makes the densest, 

 finest turf and carpet bent the next best, while Rhode Island bent is 

 slightly coarser. All these, however, either alone or in mixture, make 

 the finest, smoothest turf of all northern la^m grasses. 



(10) It is recommended that seedsmen employ the following 

 common and scientific names for the grasses described in this bulletin. 



Redtop — Agrostis palustris Huds. 



Rhode Island bent — Agrostis tenuis Sibth. 



Colonial bent — Agrostis tenuis Sibth. 



Velvet bent — Agrostis canina L. 



South German mixed bent — Agrostis spp.
