8S AMERICAN FERN JOURNAL 
I have found many plants of Aspleniwm pinnatifidum, 
and A. bradleyi. The same deep valley which separates 
Sand Mt. from Lookout Mt. extends from Fort Payne 
to Trenton. On both sides of this valley are high 
precipitous walls of rocks. On these rock walls is where 
A. pinnatifidum and A. bradleyi are to be found. I 
wanted to explore these cliffs near Fort Payne to see if 
these two spleenworts were as plentiful there as at 
Trenton. Reaching the cliffs I searched for some dis- 
tance along the road which leaves the mountain at this 
place, finding a number of plants of A. pinnatifidum, but 
found none of A. bradleyi. I could not spend as much 
time as I would like, as I wanted to take the train for 
Trenton, for I felt I had walked far enough. 
As I left Sand Mt. I noted a change in the flora. As 
the sandstone gave way to limestone, Pellaea atro- 
purpurea and Asplenium parvulum began to appear, 
as these plants prefer limestone to sandstone. 
Taking the train I soon reached Trenton, and after a 
seven mile walk reached home, ending one of my most 
interesting tramps.

Some Recent Fern Literature. 
Maxon, W. R. New selaginellas from the western 
United States. Smithsonian Misc. Coll. 72; no. 5. 
pl. 1-5. 22 Dec. 1920. 
In the paper bearing the above title, Maxon presents 
descriptions of six undescribed species of Selaginella. 
Five of these are from southwestern United States; 
the sixth from Montana. It will be of interest to 
American fern collectors to list here the names and type 
localities specifically. All are described at length and 
well illustrated by half tone reproductions of whole 
plants.
