128 POA NEMORALIS. 
ovate, acute, of three or four 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 palee; 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 jomt 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.
