licate pinnae, which Thelypteris and Noveboracense never 
do. I found also that small plants of this fern were al- 
most identical in appearance with those of A. Filix-foem- 
ina. I communicated these facts to Mr. Davenport la- 
ter on and it was the resemblance of the fern in certain 
stages to lady fern that caused him to name the plant 
A. simulatum. 
I then remembered that I had seen what at the time 
I considered to be an immense amount of this narrow 
contracted form of lady fern growing years before at 
Folly Mill Woods in Seabrook, N. H., and had collected 
specimens. I made a trip to the place to look the mat- 
ter up. I found that in my old locality for the supposed 
lady fern there was to be found an abundance of the new 
Aspidium and very little of the Asplenium, the ground 
having become shaded by a growth of young trees, but 
in the immediate neighborhood I found a place where 
the trees had been cut away recently and there the new 
fern with conduplicate pinnae was abundant. 
I looked up my specimens and in doing so I also found 
that I had collected some fronds of the new fern which 
had grown under normal conditions as forms of Aspid- 
ium Noveboracense. These fronds were collected about 
1880. My second visit to the locality about which I 
have been writing was made in August, 1892. . . 
When I sent the package of hybrid fronds and notes 
on the hybrid fern to Prof. Eaton in the autumn of 1892, 
I included in the bundle ffonds of this fern which Mr. 
Davenport has termed Aspidiuwm simulatum and also 
gave Prof. Eaton the results of my observations on it. 
Prof. Eaton requested me to send him plants of the fern 
for cultivating and I did so. 
When I made the appointment to meet Mr. Daven- 
port at Crooked Pond in Boxford, I placed some freshly 
gathered fronds of simulatum in my vasculum. After 
we had examined the hybrid plants at the foot of the
