 erne 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

 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.

 the close of July.
