MORTUS GRAMlNliUS WOBURNENSIS. 185 



AGROSTIS vulgaris canina. Awned Fine Bent. 



Specific character: Calyx valves nearly equal, blossom 

 valves very unequal ; awn jointed, tw^ice the length of 

 the corolla, fixed just below its middle. Native of 

 Britain. Root fibrous, perennial. 



Experiments. — At the time the seed is ripe, the produce 

 from a sandy loam is 6,12o lbs. per acre. 



Results go to prove, that the comparative merits of the 

 agrostis vulgaris exceed those of the agrostis vulgaris ca- 

 nina nearly as 2 to 1. The crop of the awnless variety is 

 greater than that of the av^^ned, but is much less nutritive, 

 being as 10 to 7: the spring and autumn produce is like- 

 wise superior. Neither of these varieties appears to be of 

 much value to the farmer. 



The brown bent flowers in the second and third weeks of 

 'July, and ripens the seed in the end of August. 



AGROSTIS lobata. Lobed Bent, Sea-side Bent. 



Specific character : Panicle spike-like, densely crowded 

 with florets ; calyx valves equal, acuminate, outer ser- 

 rulated from the keel upwards, inner valve only towards 

 the top, very unequal, egg-shaped. Native of Britain. 

 Root perennial, fibrous. 



Experiments. — At the time of flowering, the produce from 

 a siliceous sandy soil is 6,806 lbs. per acre. 



The general appearance of this plant indicates the inferior 

 comparative value manifested in the above details. I have 

 never met with it in a wild state. It does not appear to be 

 of much value to the agriculturist. 



It flowers in the first week of August, and the seed is 

 ripe about the end of the same month. Found near 

 Epsom. 



AGROSTIS stricta. Rock Bent, Upright ^ent. 

 Trichodium rupestre. 



Specific character : Panicle branches subdivided, roughish ; 

 calyx valves acuminate ; blossom one valve, awned ; 

 awn fixed a little above the base.
