The Brown Bent flowers in the second and third weeks of July, and ripens the seed in the 



end of August. 



Agrostis lohatn, Lobed Bent, Sea-side Bent. 



Specific character: Panicle spike-like, densely crowded with florets; calyx-valves equal, acu- 

 minate, outer serrulated from the keel upwards, inner valve only towards the top, very 

 unecj[ual, egg-shaped, 



03*.— Stems from four inches to a foot in height, according to the nature of the soil it grows 

 in ; inner valve of the blossom one half the size of the outer ; leaves flat, those of the culm 

 very rough ; culms smooth, ascending ; sheath-scale broad, divided at top : the whole 

 plant of a light green colour. I can find no other account of this grass but the following : 

 " Finding this maritime species (arenaria) noticed originally by us on the Devonshire coast, 

 not confined to sandy soils, we have changed the name to that of lohata; the panicle being 

 more obviously divided into lobes than any of the other species, it comes near to alha!' 

 Curtis, Obser.-l^ the form of the panicle it approaches the nearest to the lesser^leaved 

 variety of Creeping Bent, but the plant is not in the least stoloniferous. 



Native of Britain. Root perennial, fibrous. 



Bxperiments.-M the time of flowering, the produce from a siliceous sandy soil, is.
