A new hybrid Asplenium! 
WILLIAM R. MAXON 
Among the ferns forwarded to the National Museum 
for identification during the past year are the very 
interesting specimens forming the subject of this article. 
They were collected from sandstone cliffs of Sand Moun- 
tain, about two and one-half miles west of Trenton, 
Georgia, by Mr. E. W. Graves. The first ones sent 
in were regarded doubtfully by Mr. Graves as an aber- 
tant form or variety of Asplenium pinnatifidum. In 
the light of further field study, however, and from 
examination of the additional specimens secured, it 
‘ppears nearly certain that this form is instead a natural 
hybrid between Aspleniwm Bradleyi and A. pinnatifidum, 
with which it habitually grows. 
At the request of Mr. Graves the hybrid is described 
below. It is a pleasure to commemorate in this con- 
hection the name of the persistent and discriminating 
collector, 
Asplenium Gravesii Maxon, hybr. nov. 
Intermediate between A. Bradleyi D. C. Eaton and 
A, binnatifidum Nutt., the fronds few or several, loosely 
fasciculate, ascending, 10 to 13 cm. long; rhizome de- 
cumbent or short-creeping, 1 to 1.5 em. long, densely 
Paleaceous, the scales about 5 mm. long, linear, long- 
ae eras,
