Fern Fitora or ALABAMA 73 
ASPLENIUM PLATYNEURON INCISUM (E. C. Howe) 
Robinson. This variety I have found only in Mobile 
Co., near Spring Hill, in a deep damp ravine. This 
is a very beautiful fern with its pinnae deeply cut, often 
nearly to the midrib. The fronds were fourteen to twenty 
inches high. 
ASPLENIUM EBENOIDES R. R. Scott. This hybrid 
has been found only in two counties of the State, Hale 
Co. and Marion Co. In 1918, I visited the station at 
Havanna in Hale Co. I found the fern still holding 
its own, but the plants were mostly small. I had quite 
a hard time finding the ravine and it was nearly dark 
when I came to the plants. I counted about fifty in 
all. It grew on almost the same kind of stone that 
I have found most of A. pinnatifidum growing on, 
apparently a sort of sandstone. It certainly was not 
limestone. 
ASPLENIUM PARVULUM Mart. & Gal. Tennessee 
valley to lower hills. Growing on limestone on shady 
hillsides. I have found it only in Jackson and DeKalb 
Counties, being quite plentiful there. Mohr reports 
it from Lawrence, Lauderdale, Walker, Madison, Bibb, 
and Clay Counties. 
AspPLENIUM TRICHOMANES Lz Damp sheltered rocks 
and open caves, called in Alabama ‘rock houses. ”’ 
Not plentiful anywhere. Jackson, DeKalb, Etowah, 
Talladega, Tuscaloosa, and Clay County. 
ASPLENIUM MoNnTANUM Willd. Mountain region, 
rare in most places. There are one or two places on 
Sand Mt. where it is rather common. It grows out of 
the crevices of sandstone, often in large clumps. I
