THE SEAWEEDS 
Owing to the abounding fluid content and easy dissolution it is difficult 
to preserve satisfactorily in dried specimens. 
Abundant on the coasts of Western Australia, from Geraldton to Albany, 
it seems to be rarer or to have escaped general notice in South Australia, 
though it has been collected at Denial Bay by Dr. G. A. Chambers, and 
at Grange near Adelaide by Dr. J. B. Cleland. I have not seen it in Victoria 
but found it on the north coast of Tasmania. It is common again all up 
the east coast of Australia and occurs in New Caledonia.

Globular forms. 
Two species of globular Codia are met with in South Australia, 
C. pomoides and G. mamillosum. Both are irregularly spherical or rounded 
in shape, and grow attached to rocks by a considerable base. We occa-

sionally come across numbers of them of all sizes adhering like anemones 
to the under face of an overhanging ledge of rock but they are not confined 
to such situations. They grow in the close neighbourhood of low-water 
mark. Full grown plants may attain a diameter of three or four inches. 
Broken away by storms they can often be gathered on the beach out of 
the masses of cast-up weeds. Both have very long utricles but in neither 
have gametangia been as yet observed, though they have been noted in 
the allied C. bursa.
