58 FERNS OF KENTUCKY. 
such information as we have of its growth in Kentucky. 
He found it in June, 1874, in a single locality, near Bee 
Spring, Edmonson County, about twenty miles west of 
Mammoth Cave. He has given me the following descrip- 
tion of this region: “ All its water-courses, even the small- 
est wet-weather brooks and spring branches, take their rise 
between a series of steep cliffs, which form an elevated 
water-shed between Bear Creek and Nolin Creek, both trib- 
utaries of Green River, running in parallel courses, from five 
to ten miles apart, for a distance of twenty miles. This 
water-shed is intersected on either side by deep, high- 
walled ravines, whence gush forth cool springs, which 
either sink in the porous sandstone or murmur and plunge 
headlong to these rapid creeks. Under the overhanging 
sand-rocks, sheltered from the sun and sweeping winds, 
are sometimes spaces of vast extent, where the aborigines 
had their homes, as evinced by the numerous fragments of 
flints, and by the mortar holes in the detached masses of 
sand-rock. On one of these sandstone cliffs I found the 
Asplenium Bradleyi, and, recognizing it as new, I sent it to 
Dr. A. H. Curtiss, a botanical correspondent, from whom 
I learned that Prof. Eaton had already described it. On 
revisiting, in 1877, the spot where it was found, very few © 
fronds could be obtained, and care should be taken that it 
is not exterminated. I have searched a hundred similar 
localities without finding it. It was found along with the 
A. montanum and A. pinnatifidum, and not far from A. 
ebeneum. Under a moist, overhanging rock, a few hun- 
dred yards distant, was found the Trichomanes radicans, 
shut out from direct sunlight, and where there was constant 
dampness.” 
In the summer of 1876, Mr. C. C. Haskins, of New 
Albany, Ind., found a few fronds of this rare fern in the
