Var. FITZGER- 

 AI.DII (R. and C.). 

 I cannot agree 

 with Mrs. Britton. 

 whom I followed 

 in the FIRST EDI- 

 TION, in making 

 this a synonym of 

 var. orthocarpa, 

 as it appears to be 

 a southern and seaboard form, being very abundant about New 

 York city. The capsules are only lightly striate until very old, and 

 the mouth is slightly or not at all oblique. It has been found 

 along Lake Champlain and may occur near the Great Lakes. 



In the Bulletin of the Torrey Botanical Club for Novem- 

 ber, 1895, Mrs. Britton describes and figures a very interesting 

 mountain form with pedicels strongly curved backwards which 

 straighten in drying so as to assume the normal form. 



D. CERVICULATA (Hedw.) Schimp. grows in wet places, 

 typically on peat. It appears to be rare. The plants are 

 smaller in every way than the last, the leaves are 



less falcate, with 

 a half-sheathing 

 base, often 

 n e a r ly entire; 

 capsule arcuate 

 and gibbous, 

 with a clearly 

 strumose neck.
