AA. Sori large (always over 2 
mm. long), oval or oblong, often 
contiguous, confined to the mar-

tered on the blade. 
C. Sori in 1 row on each side of

indistinct.

DESCRIPTION OF SPECIES. 
1. C. rupestris (R. Br.) C. Chr. Ind. 200.1905. 
Cyclophorus serpens Forst. var. rupestris Domin, Biblio- 
theca Botanica XX, p. 187, 1915. 
Poly podium serpens auct. Austr. non Forst. Benth. FI. 
Austr. VII., 767 (1878), Queensl. FI. VI. 1984 (1902). 
Rhizome slender, long-creeping, densely covered with 
spreading long, narrow, acuminate, pale brown fugacious 
scales. Fronds small but growing in large matted patches, 
coriaceous, obtuse, contracted into a rather long stipes, 
densely covered on the lower surface and more loosely on 
the upper one with stellate hairs, the barren ones obovate 
or oblong, 1-3 cm. long, the fertile ones linear or oblong- 
linear, 2-6 cm. long. Venation reticulate but concealed in 
the thick texture, and the dry frond even rugose with 
indented lines not connected with the veins. Sori not very 
large (usually under 2 mm. long), irregularly crowded 
over almost the whole frond, somewhat immersed, usually 
confluent and indistinct when old.
