GRASSES OF BRITAIN. 221 



Pua Burreri is distiriguished from Poa maritima in the spikelets not 

 being half the size : panicle more rigid and compact : and the Ugule 

 shorter and more blunt. 



Poa Borreri is distinguished from Poa distans in the panicle being 

 more rigid and compact : the branches never deflexed : and the middle 

 rib of the florets reachiug to the summit. 



Mr Babington, in a supplement to Sowerby's English Botany, 

 t 2797, has figured and described this grass, but the figure does not 

 appear to be very characteristic of the plant He states that it is far 

 from being uncommon on the English coast, having been gathered 

 by ^Ir Bon-er at Gosport. Selsea, Southampton, Stokes Bay, Shore- 

 ham, and Freshwater in the Isle of Wight Mr Babington has no- 

 ticed it at Harwich, and on the Canvey Isle, near the mouth of 

 the Thames. It is found mostly in brackish ditches, often in com- 

 pany with Poa procumbens. 



Flowers in July.

 mis fructiferis erecto-patulis, spiculis 5-9 floris, Jloribns lineari-ob-
