 152. HAY SEDGE 



CAREX FOENEA Willd. 



We have no notes on this sedge except the fact that it occurs in 

 our collection. 



153. BRISTLE-STALKED SEDGE 



CAREX LEPTALEA Wahl. 



A tall sedge growing rather scattered among the sedges and 

 grasses of low flat marshes. Not conspicuous, but rather pretty. 

 The spikes are rather small, but attractive on account of the color 

 contrast between the pale or whitish perigynia and green subtend- 

 ing scale. Color efi'ects of any sort are rather infrequent among 

 sedges, the entire plant except the scales of the staminate flowers 

 and the yellow anthers and white pistils being usually about the 

 same shade of green, but here we have the monotony somewhat 

 relieved with well marked difference in shade. 



Collected in flower over by the tamarack May 22, 1901, and 

 noted in blossom north of the lake June 18. 



154. PENNSYLVANIA SEDGE 



CAREX PENNSYLVANICA Lam. 



One of the most familiar sedges to be found in open woodlands 

 and one of the earliest plants to bloom in spring. It usually grows 

 in scattered tussocks in dry woodlands, but sometimes the tussocks 

 grow close together forming small patches where it forms a firm 

 mat over the ground. On account of the curled touseled character 

 of the leaves, which become brownish when old, it is in some places 

 known by the suggestive name of dog's hair grass. 



The fruit is inconspicuous and scant. 



April 6, 1901, nearly in blossom by Farrar's. April 19, nearly 

 in flower west of the lake ; April 25 fully in flower by Chadwick's ; 

 April 26 some fully in blossom in Farrar's woods ; April 30 in blos- 

 som everywhere. It ripens early in the summer. Nearly ripe 

 fruit was collected June 17. 



155. WHITE BEAR SEDGE 



CAREX ALBURSINA Sheldon 



This sedge is remarkable for its very broad whitish leaves. It 

 never grows in patches, but is usually found singly and scattered in 

 deep shade of rich woodlands. The fruit is scarce and inconspicu- 

 ous. It was found in various places about the lake, principally 

 in the deep woods on the east side.
