August, 1937. The Queensland Naturalist. 
Distribution. — Eastern Australia (Queensland, New 
South Wales and Victoria). 
Domin in Bibliotheca Botanica XX. p. 187, 1915, 
states that the typical C. serpens does not occur on the 
mainland of Australia, but is confined to New 7 Zealand, 
New Caledonia and Norfolk Island. He places the Aus- 
tralian plant under 0. serpens , Forst. var. rupestris (R. 
Br.) Domin. Christensen in his Index, p. 200 has, and 
I think rightly so, elevated our plant to specific rank. 
Cyclophorus rupestris C. Chr. has a fairly wide distribu- 
tion in Queensland, being recorded from Moreton Bay, Mt. 
Perry, Rockhampton, Rockingham Bay, Bellenden-Iver, 
etc., and its southernmost limit in Australia, as far as is 
known, is in the vicinity of the mouth of the Snow 7 y River 
in Victoria.

Rhizome slender or rather robust, long-creeping, 
branched, densely covered with adpressed scales, the 
scales peltate, dark brown, lanceolate, acuminate, fimbriate 
with soft v r hite hairs when young. Fronds linear-lanceo- 
late or linear, or the sterile ones oblong to obovate, apex 
obtuse, tapering into a stipes |-2 cm. long, the fertile 
fronds longest, usually 7J to 10 cm. but sometimes up to 
23 cm. long, 14 cm. broad, coriaceous, pale green above 
and sparsely covered with dark-coloured, fugacious, stel- 
late hairs, the hairs very dense on the lower surface. Veins 
reticulate but concealed in the thick texture. Sori large, 
oval or oblong, in one row on each side of the costa, usually 
contiguous or densely confluent and indistinct when old. 
Distribution. — Queensland, New 7 South Wales, Lord 
Howe Island, Norfolk Island, New Caledonia, New Zea- 
land, and New Guinea. 
In Queensland this species has a distribution very 
similar to that of the preceding species. In New South 
Wales it extends as far south as Newcastle.

in the normal form. 
Distribution. — Queensland : Main Range, Helidon :
