GENERA AND SPECIES. 57 
PLATE XV. 
ASPLENIUM BRADLEYI. D. C. Eaton. 
BRADLEY’S SPLEENWORT. 
This exceedingly rare fern has been found only in Ten- 
nessee and Kentucky, and was named in honor of Prof. 
F. H. Bradley, of the East Tennessee University, who 
discovered the plant originally on the top of Walden’s 
Ridge in the Cumberland Mountains, near Coal Creek, 
East Tennessee, in 1872. 
To enable other botanists to recognize the more readily 
this rare little fern, I will give Prof. Eaton’s description of 
the species: “ Mature plant 8-10 inches high; root-stock 
short, covered with narrow, acuminate fuscous - black 
scales; stipes tufted, slender, ebeneous, as in the lower 
half or two thirds of the rachis; fronds membranaceous, 
oblong-lanceolate, varying to linear oblong, the largest ones 
5-7 inches long, and 144-2 broad, pinnate; pinnez rather 
numerous (8-12 pairs), the lower ones more distant than 
the median ones, and of similar size, all short-stalked, 
oblong-ovate, obtuse or acutish, more or less incised, in 
the largest pinnatifid with oblong lobes which are toothed 
at the apex, in the smallest deltoid-ovate, slightly toothed; 
fruit-dots short, near the costules; indusium delicate. It 
differs from A. montanum in its larger size, more membra- 
naceous texture, narrower outline of the fronds and shorter 
stalked pinne.” * 
Although I have collected in all the localities in this 
State where it is likely to be found, I have never met with 
it, and I am indebted to Prof. Hussey for the specimens 
from which my drawing has been made, and mainly for
