 be considered as one of the important species of the region ; its

 live upon the grasses of the SAvamp meadows and form one of the 

 most conspicuous features of these associations. Cranberry Lake,

 siderable moisture and shade. Tt is too rare to be of economic 

 importance. Barber Point. Aug. 5, 1920. Bear Mountain.
