128 POA NEMORALIS. 



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.
