34 PHLEUM BOEHMERI. 



three-fourths of the length of , the glumes, consisting of two 

 equal-sized palese, the exterior one being five-ribbed and roughish, 

 the inner one membranous. Ovarium hirsute, scales bold, styles 

 two, stigmas feathery, stamens three. Length from six to eigh- 

 teen inches. 



Flowers in July, and the seeds become ripe about the middle 

 of August. 



The present species differs from PMeum asperum in not 

 having the glumes cuneate, in not having a long and pointed 

 ligule, and in having the keels fringed. It difiers from P. 

 arenarium in having the floret entire instead of jagged at the 

 apex, in the floret being much longer in comparison to the 

 glumes, and in the inner edges of the glumes not being fringed 

 with diminutive hairs as in P. arenarium. From P. Michelii 

 in having more linear-shaped glumes, and in having only the 

 upper portion of the keels hirsute, instead of throughout their 

 whole length, as in P. Michelii; whilst from P- pratense it differs 

 in the glumes being pointed and destitute of awns, and the inner 

 edges ending obliquely instead of abruptly. Also in the exterior 

 palea having the apex entire instead of jagged, as in P- pratense. 



The specimen illustrated was procured in Norfolk by Mr. 

 Joseph Sidebotham, of Manchester.
