36 PHLEUM ARENARIUM. 



Sometimes it does not exceed three inches, at others it is five times 

 this length. 



Phleum arenarium has much smaller spikelets than P. michelli, it 

 is notched at the summit instead of being entire, and the glumes 

 not hirsute on the lower half of their keels. It differs from P. pratense 

 in being smaller, the base of the panicle contracted, and having no 

 awned floret. 



Conies into flower in the middle of July, the seeds becoming ripe 

 in about a month. 



The specimen illustrated was gathered at Fleetwood, by Mr. Joseph 

 Sidebotham, of Manchester. 



Phlenm arenarium. From a dwarf specimen.
