Winslow: Ferns of Massachusetts 15 



for L. complanatum, but is probably L.flabelli forme X tristach- 

 yum. It compares well with plants that I have collected 

 in a similar situation and with the same associates in Ver- 

 mont, and with a plant recently sent me from Connecticut 

 concerning which Mr. Bigelow reports that he found it 



with tristachyum and flabelliforme. 



Of six Dryopteris hybrids collected, all but the first

Cheshire. 



D. Goldiana x marginalis, — One plant, a fine large one.

D. cristata X marginalis, — Rather common in swamps. 



D. cristata x spimdosa intermedia, — Common in wet

closed localities for Phegopteris hexagonoptera, which ifl 

 recorded from Williamstown and Lenox, possibly Wood- 

 wardia mrginica, almost surely Equisetum fluviatik. In 

 the limestone regions about Lake Champlain one may
