86 AMERICAN FERN JOURNAL 
Asplenium trichomanes L. is fairly common through- 
out Vermont, but its form inciswm Moore is ex- 
tremely rare. The latter has been reported, I believe, 
from Brattleboro, Hartland, and Norwich. The most 
deeply cut specimen of this form I have ever seen is in 
the Jessup Herbarium at Dartmouth College. Asple- 
nium platyneuron (L.) Oakes is frequently met with. Its 
variety serratum (E. 8. Miller) B. S. P. has been found in 
Pittsford and the variety incisum (E. C. Howe), named 
by Davenport as Asplenium ebeneum var. Hortonae, has 
__ been reported from Brattleboro and also from Pittsford, 
_ the latter one of the richest towns in the state in respect to 
itsfern flora. Miss Slosson has reported forty-five species 
oo and six varieties from a three-mile triangle at Pittsford. In 
ay addition she has found there several of the hybrids, in- 
_ cluding the very rare Dryopteris marginalis x spinulosa 
_Slosson._ Although this fern was recognized by Miss 
on as a hybrid when it was first described, it was 
name pittsfordensis.* A new station for this — :

great variety of ferns reported from Pittsford, as well as
