scales. Fronds membranous, somewhat distantly placed on the 
rhizome, simple or variously lobed, and either form soriferous, 
glabrous, 6 to 12 in. long, tapering to a rather long stipes and 
elongated apex, the undivided fronds attaining a vsridth of 2 in. in 
the widest part, lobes on the divided ones from 1 to 12, spreading 
tapering towards the point, but cut down so as to leave but a wing 
on the costa in the sinus about i or | in. wide, the segments varying 
from 1 to 4 in. long ; venation rather open, forming large hexagonal 
areoles containing forked free veinlets ; sori in short lines or oblong 
masses, often not exceeding 2 or 3 lines on the divided fronds, and 
distant from the costule, but on the entire simple fronds often reaching 
from near the costa to near the margin, but these lines are frequently 
interrupted. 
Hab. : Bellenclen-Ker, at an elevation of 4,000 feet. 
The habit of this fern and its variously formed fronds reminds one of Poly- 
podium scandens, Forst., and further, when dry, it possesses the same fragrance as 
that and some allied Polyjpodiums. To pteridologists, the meeting of this species, 
bearing its various forms of foliage, is most interesting, as it saves the mistake being 
made of multiplying species, and comiDletes the description of an old species. G. 
Sayeri, F. v. M. and Baker, has been named from fronds of this species ; and in 
all probability G. Wrightii, Hook,, is but another form, I might here remark that 
probably Mr. Baker was not far wrong when ho placed the Queensland fern, 
G. ampla, F. v. M., under G. elliptica, for it varies greatly in the form of the 
fronds. In cultivation, the fronds are much smaller and often entire, and these as 
frequently bear sori as the more developed deeply lobed ones. On starved plants, 
indeed, of G. ampla, the almost only distinctive mark to separate it from G. mem- 
hranacea is its broad flattish rhizome and a slight difference, perhaps, in the 
venation.
