Diagnosis | Colonial or solitary hydroids. Stolons often in polysiphonic bundles, with smooth perisarc. Unbranched or sparingly branched erect shoots bearing terminal hydranths. Perisarc of hydrocaulus expanding towards distal end, often subdivided into several imbricating cones, terminating at the base of the hydranth or slightly above; perisarc double-layered, with surface distinctly striated by longitudinal creases; the two perisarc layers connected by many oblique lamellae giving the impression of a cross-striation with the longitudinal striae. Hydranths with rounded hypostome and irregularly scattered filiform tentacles. Sporosacs without perisarc covering, without tentacle rudiments, without ring or radial canals. Female sporosacs with about ten or more eggs. Male gonophores unknown. Cnidome comprises microbasic euryteles, desmonemes, and a further, unidentified capsule. |
