PrERIS SERRULATA L. Very common in Mobile 
Co. First observed in 1870, since spreading along the 
banks of water courses and ditches, and on old walls. 
In the city of Mobile one finds it growing on most all 
brick walls, sometimes ten or fifteen feet above the 
ground. Dr. Smith sent me a specimen from Tusca- 
loosa where he found it growing. 
Preris LoNGIFOLIA L. This fern to my knowledge, 
had never been collected in the State, until I found 
about a dozen plants growing on a brick wall on West 
Congress St., in Mobile. The building was old facing 
the east, and shaded by a large tree. On the wall with 
P. longifolia. grew Dryopteris normalis, Pteris serrulata, 
and several weeds. The plants were not large; some 
had fronds perhaps fifteen inches long. Most of them 
were much smaller. 
CHEILANTHES ALABAMENS(S (Buckl.) Kunze. Grows 
on limestone in north part of the State. Dr. E. L 
Lee, of Bridgeport, Ala., told me that it grew plentifully 
on the west side of Sand Mt. near the Tennessee river, 
but I never saw it in the county. I found it growing 
rank, almost a foot tall, near Florence, in Colbert Co. 
Mohr reports it from Winston Co., Etowah Co. and 
Bibb Co. 
CHEILANTHES LANOSA (Michx.) Watt. Mountain 
region of the northern half of the state, on sandstone. 
I have found it in Jackson Co., Jefferson Co., Colbert 
Co., DeKalb Co. and Hale Co. Mohr reports it from 
Cullman, Lauderdale, and Tuscaloosa counties. Smith 
reports it from Bibb Co. 
CHEILANTHES TOMENTOSA Link. Rather common 
in the mountain region of the north. On Sand Mt. it 
grows at an altitude of 1200 ft. I have never found it 
lower than 600 ft. Mohr reports it from Cullman Co. 
800 ft., Blount Co., 600 ft., Talladega Co., Alpine Mt. 
Signal ‘Station: 1800 ft. jae Lauderdale Co. ., 500 ft.
