144 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
In the original description the margins of the pinne are mentioned as entire, which 
is by no means invariably true. In a majority of specimens they are nearly entire, 
and the leaf tissue is so coriaceous that, unless rather strongly cut, the slightly revolute 
margins commonly appear to be entire or subentire. But in other specimens they are 
crenulate, or even deeply crenate in unusually luxuriant plants which may have 
grown in deep shade or under exceptional conditions. The veins, excepting the 
lowermost superior one (which is several times forked), are mostly once-forked, the 
sorus commonly being borne altogether upon the anterior branch. The sori are thus, 
on account of their origin, short and as a rule situated nearer to the margin than to the 
midvein. With age they are readily confluent, forming a broad marginal band around 
the pinne, or even completely covering the under surface. 
The name Asplenium resiliens, which is the one under which this species must be 
known, was given by Kunze solely to replace the untenable name A. parvulum Mart. 
& Gal. (1842), which is invalidated by A. parvulum Hook. (1840). This fact, which 
was pointed out by the writer in 1902! and recognized by Mr. Gilbert in his dis- 
cussion of A. muticum,? was yet disregarded by him in his later notes upon that spe- 
cies,* when he suggested that ‘‘parvulum” and ‘‘resiliens” may represent two different 
forms or even species. As a matter of fact, A. resiliens is, within well established 
limits, a variable species, but hardly more so than a majority of those ferns which 
occupy equally extensive ranges. In this case the points of difference are not cor- 
related with geographic distribution, as Mr. Gilbert erroneously surmised from his 
meager material. 
This species has been well described repeatedly of late. Besides the difference in 
marginal form there is considerable variation in the shape of the pinnee. Those of the 
middle part of the frond are commonly oblong and auriculate only at the upper side 
of the base; but occasionally (for example, in Arkansas specimens collected by Mr. 
James H. Ferriss) they are strongly auriculate both above and below, a form which is 
usual in the shorter dwindling lower pinnae of most specimens. The largest indi- 
viduals seen are plants collected near Blount Springs, Alabama, by John Donnell 
Smith, in 1884, measuring 35 cm. in height. The species is 2 common one in the 
southern United States and apparently prefers limestone.
