A variable species in habit, generally more robust than the preceding, but only to be known with certainty by 

 the form of the receptacles. We have not seen atty New Zealand specimens of 0. monilifera, but have from Dr. 

 Lyall specimens collected in Cook's Straits, which in some respects are intermediate in character ; having the dense 

 ramification, broad stem, and strongly aculeated bases of the branches and spherical vesicles of C. monilifera, with the 

 ensiform subtorulose receptacles of G. retroflexa.

This plant is included in our former list of New Zealand Algae, but we are not certain of the correctness of the
