AGRICULTURAL SPECIES OF BENT GRASSES. 13 
(8) Carpet bent (Agrostis sp. indet.) and velvet bent (Agrostis 
canina L.) make up much of the 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 fine bents. 
| (9) Redtop 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 lawn 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.
