FURTHER INFORMATION REGARDING THE OCCUR- 
RENCE OF DRYOPTERIS FILIX-MAS IN 
VERMONT. 
' 
MABEL A. STRONG. 
On the twelfth of last August, while spending a day in the woods. 
in central Vermont I had the pleasure of finding Dryopteris Filix- 
mas. At first I saw only five or six clumps, containing from one to 
six plants each and growing in a partially exposed place, seemingly 
an old wood road or spring water course and overgrown with thin 
grass, dwarfed raspberry bushes and weeds; but upon a second visit 
and more careful exploration I counted over forty clumps comprising 
a hundred or more plants and extending farther into the deeper 
woods. ‘The whole group, so far as observed, covered an area which 
one might have walked around in perhaps three minutes. The 
individual ferns varied from tiny ones to magnificent specimens 
waist high. 
Noticeable at the edge of the deeper wood and shading some of the 
ferns in question are several large butternut trees. ‘The soil is very 
black and rich while the underlying and partially exposed ledges 
are of a lead-colored rock. At the left side of this road or water 
course is a thick growth of sapling maples, but none of the ferns. 
were found there. 
This wood crowns the top of a pasture hill at an elevation of about 
sixteen hundred feet and has a northern exposure. It is situated 
in the southwestern corner of the town of Woodstock near the Bridge- 
water and Reading lines. In other words it is about six miles due 
west of Hartland Four Corners, where Miss Darling discovered this. 
fern over a year ago. 
Growing in the midst of the area just described is one fine clump 
of Dryopteris Goldiana and distributed through the woods are quanti- 
ties of the finest specimens of Braun’s Holly Fern I have ever seen, 
excepting those growing near the summit of Killington. 
Several other species of Dryopteris are found in the immediate 
vicinity, namely D. spinulosa, D. marginalis, D. noveboracensis, and 
D. acrostichoides, while somewhat lower on the slope and in the open. 
pasture occur Dicksonia, Adiantum, and Asplenium Filiz-foemina.
