110 POA MARITIMA. 



outer glume. Florets of two equal-sized paleae; exterior one of basal 

 floret sharp-pointed, base slightly hirsute; smooth above, five-ribbed. 

 Inner palege having two green marginal fringed ribs. Length six to 

 twelve inches. Root creeping and perennial. 



Flowers at the beginning of July, and the seeds become ripe in a 

 month. 



P. maritima differs from P. distans in having its rachis and branches 

 smooth to the touch, its root creeping, and its central rib of outer 

 palea extending to the summit. It also differs from P. procumbens in 

 its smooth rachis and branches, and creeping root. 



The specimen for illustration was gathered near Bristol, by Mr. Joseph 

 Sidebotham, of Manchester.
