Cylindrical nectophores with solid mesogloea. The simple somatocyst extends beyond the point of origin of the pedicular canal. Extensive hydroecium, not reaching the base of the nectophore. Nectosac opens basally. Bract similar to Rosacea cymbiformis, but dorsal canal arises from right hydroecial canal distal to the short longitudinal canal. The nectophores of these two Rosaceaspecies can be difficult to tell apart. Generally Rosacea cymbiformis lives at shallower depths than Rosacea plicata.
