AN ADIRONDACK FERN List 83 
one of these was sent to the Society garden at the 
Brooklyn Botanic Garden. 
“Athyrium acrostichoides, A. filix-femina. The latter 
is common, the former not very. 
Dennstaedtia punctilobula. Frequent, at its best in 
open sunny places, but common in shades from swamps 
to mountain tops. 
Dryopteris cristata, D. cristata x intermedia, D. cristata 
x sprnulosa, D. dilatata, D. dryopteris, D. intermedia, D. 
noveboracensis, D. phegopteris, D. simulata, D. spinu- 
lesa, and D. thelypteris. The most interesting thing 
about this list to me is the absence of D. marginalis, 
the commonest fern in the central New York woods. Is 
it common anywhere in the Adirondacks? Do the high 
altitude and long winters exclude it? As a matter of 
fact the winters though long and cold are not hard on 
herbaceous plants because there is such a deep snow 
blanket that the ground freezes very little. 
D. simulata I reported some six years ago in Torreya 
as from the north side of Quiver Pond, a small lake near 
Fourth Lake. This summer I found it in much greater 
quantities along a little trickle which made its way 
under the logs of an old abandoned corduroy road 
formerly used in lumbering operations. The locality 
is near Third Lake Creek and south of Quiver Pond. 
The little stream followed the corduroy road for a 
quarter of a mile and everywhere the simulata was 
abundant. Sphagnum is scattered everywhere, and 
its concomitant moisture. Has anyone ever found this 
fern in anything but boggy or sedgy situations? : 
D. dilatata was found only once on Blue Mountain, 
from three thousand feet to the top about thirty-eight 
hundred feet high. I have never found it at lower 
elevations in the Adirondacks. The mountains whose 
tops range about twenty-five hundred feet do not seem 
to furnish the right conditions for it- That 1 may 
 oceur at lower elevations is undoubted, but I believe
