A New Station for Trichomanes Petersii 
E. W. GRAVES 
On the 24th of October, 1916, Mr. A. H. Howell, 
of the United States Biological Survey, and myself 
started on a trip toward the south end of Sand Mt., 
Alabama. Sand Mt. is an elevated plateau ten miles 
wide, extending from near the Tennessee line southwest 
about one hundred miles into Alabama. It lies about 
one thousand feet above the Tennessee River. 
The mountain is cut up by many deep gorges which 
empty the water of the tableland into the Tennessee 
River which lies to the west. Growing along these 
cool, damp gorges one will find a varied flora. There 
occurs a strong mingling of types that are at home in 
the Alleghenian area of the adjoining states and of 
North Carolina with plants of the lower ranges within 
the Carolinian area, the like of which has not been ob- 
served in any other part of the mountain region of 
Alabama. Among the woody plants peculiar to the 
Alleghenian area, Rhodendron catawbiense and Tsuga 
canadensis are the most prominent. Among the more 
rare ferns one finds Asplenium Bradleyi, A. montanum, 
A. pinnatifidum, A. Trichomanes and occasionally Pel- 
laea atropurpurea growing along the sandstone cliffs, 
and lower down, where the creek bed has been cut into 
the limestone shales, Camptosorus rhizophyllus and 
Dryopteris spinulosa intermedia occur. Where the 
sandstone is kept continuously wet one will find an oc- 
casional bed of Trichomanes radicans. 
On the 29th, Mr. Howell and I decided to make a 
camp in the Santy Creek gorge which in this place is 
the boundary between Jackson and Marshall Counties. 
Of course, water would be the first necessity in a camp; 
I therefore set out to find a spring. After locating a 
Tavine which emptied into the gorge, I followed it for
