Although flexuous, the apical branches are rather brittle and easily broken. The hydrothecae are mostly arranged in one plane, but on some hydrocladia there is a tendency to face frontally. The small, thin marginal replications are slightly everted and are probably remnants of opercular attachments. The hydrothecae in the branch dichotomies do not differ in size or shape from those on the internodes.
