48 The Queensland Naturalist. August, 1937. 
The single specimen in the Queensland Herbarium is 
characterised by being soriferous over a much greater 
portion of the frond than in the normal form (nearly 
half), and the sori are well separated with the exception 
of those at the apex, which are fused into a short con- 
tinuous ridge on each side of the costa. I consider it 
only to represent an occasional variation and scarcely 
worthy of a distinctive name. 
With regard to Domin’s G. spicatus (Bibliotheca 
Botanica XX, p. 189, 1915), after a careful examination 
of the material in the Queensland Herbarium, it is con- 
sidered that this represents a form of C. conflucns C. Chr. 
Extreme forms of C. confluens, with its large oval, some- 
what confluent sori covering a large part of the frond, and 
of Domin’s C. spicatus, with its compact confluent sori 
confined to the, apex of the frond, as well as numerous 
intermediate forms, are frequently to be found on one and 
the same plant.
