Eastern Bays), Victoria. 
Subfamily Kallymenieae (J. Agardh) Schmitz. 
CONSPECTUS OF THE GENERA. 
A. — Median (axile) region of the frond cellular, 
a. Cells of the median region arranged in several 
series. These cells irregularly arranged, 
separated by meatuses Callophyllis 
Kutzing. 
b. The largest cells of the median region forming 
a single series Polycoelia 
J. Agardh. 
B. — Median region of the frond traversed by thin articulated branching, 
more or less loose filaments. 
c. Medullary filaments forked, accompanied by 
rhizoids directed towards the circumference . Kallymenia 
J. Agardh. 
d. Medullary filaments thin, traversed by single 
rhizoids Meredithia 
J. Agardh. 
CALLOPHYLLIS Kutzing. 
Frond carnose-membranaceous, flat, dichotomous or laciniated, formed of 
two strata of cells, the medullary of large rounded cells, separated by inter- 
cellular meatuses, filled with endochrome, the cortical of vertical moniliform 
filaments. Cystocarps half-immersed, superficial or marginal, containing 
within a thick closed pericarp a compound nucleus, consisting of several 
nuclei or masses of spores. Cruciate tetrasporangia dispersed through the 
cortical layer. 
Callophyllis cervicornis Sender. 
Frond di-trichotomous and then irregularly pinnate, with narrow linear 
segments, here and there with a subulate simple or bifid tooth, the upper 
segments secund breaking into teeth or prongs of the horns. Cystocarps 
immersed in the disc of ultimate laciniae. Height 5 cm. to 8 cm. Colour 
rose-purple. 
South Australia (Encounter Bay). 
Callophyllis Harveyana J. Agardh. 
Frond dichotomously multipartite, sub-fastigiate, broad, flat and entire 
at the margin, without teeth. Height 20 cm. to 30 cm. The segments are 
linear-cuneate, obtuse and from 6 mm. to 10 mm. wide. The cystocarps 
over the surface of the frond. Colour a brilliant rosy-red. The substance is 
soft and the plant adheres closely to the paper. 
South Australia (Eastern Bays), Victoria, Tasmania.
