49 
(up to 0.5 cm. long), not numerous, oval or oblong, more 
or less oblique to the costa, in some fronds forming a 
close row of 3-10 sori on each side of the midrib at the 
margin, in others irregularly scattered between the mid- 
rib and margin, often contiguous but fairly distinct in all 
specimens seen. 
Closely related to G. confluens and with very similar 
rhizome scales. The latter species differs, however, in its 
much longer, narrower fronds of thinner texture, the 
fertile ones longer than the sterile, and in its smaller sori 
usually parallel with the costa and forming 1 regular 
row on each side. Also in C. confluens the sori, when 
contiguous, become quite indistinct.

Rhizome rather robust, creeping, branched, the 1 
scales on younger parts spreading, long, narrow-acumin- 
ate, brown with pale margins, fringed with soft white 
hairs; on older parts short, adpressed, rhomboidal, pel- 
tate, dark with pale margins. Fronds linear-lanceolate, 
15-60 cm. long and 2 cm. broad, contracted into a stipes 
14-3 cm. long, coriaceous, midrib prominent beneath, 
venation concealed in the substance of the frond ; upper 
surface glabrous or nearly so, and sometimes shining, 
lower surface densely covered with minute, pale, stellate 
hairs. Sori very small, punctiform, densely crowded (but 
distinct) between the margin and midrib on the upper 
1/3 to 2/3 of the frond, slightly immersed, the im- 
pressions scarcely prominent on the upper surface. 
Distribution : — Queensland, Ceylon, Malesia, Poly- 
nesia, New Hebrides, Philippines, New Guinea. In Aus- 
tralia confined to the tropical coast of North Queensland. 
ACKNOWLEDGMENTS. 
I wish to acknowledge my indebtedness to Mr. C. T. 
White, Government Botanist, for much valuable advice 
and helpful criticism in the preparation of this paper, and 
especially for his Latin translation of the description of 
the new species.
