Blainville, 1834
Anterior nectophore with rounded apex, and without ridges; posterior nectophore of similar size with extensively looped lateral radial canals. Replacement nectophores of both types are frequently produced, and these may have different characters. Small leaf-like bracts that may not be released as eudoxids. Anterior nectophores of a few species of the diphyine genus Lensia may be confused with this genus. Bracts of various species are not distinguishable.
