188 POA NEMbRALIS. 



ovate, acute, of three or five awnless florets; the apex of basal 

 one stretching slightly beyond the large glume of the calyx. 

 Calyx of almost equal, acute, three-ribbed glumes, the dorsal 

 rib being dentate above. Florets of two paleee; the exterior 

 one of basal floret five-ribbed. The calyx is suspended in a 

 silky web at the base of the floret. Length from eighteen to 

 twenty-four inches. Colour light green. Root perennial and 

 creeping. 



Variety Angustifolia. Common. It has the first joint near 

 the panicle, and the spikelets have only two florets. 



Poa nemoralis is distinguished both from P. trivialis and 

 P. pratensis in the upper sheath not extending beyond its 

 leaf, and from P. montana and P. polynoda in the webbed 

 florets. 



Blooms in the third week in June, and ripens its seed at 

 the close of July. 



For specimens I am indebted to Dr. Wilson, of Nottingham, 

 and to Mr. J. Sidebotham, of Manchester. 



The specimen illustrated was gathered in Reddish Vale.
