Diagnosis Hydroid colony sometimes stolonal, but mostly with erect branched stem, arising from a creeping hydrorhiza; stem, branches and hydranth pedicels covered by perisarc, sometimes enveloping also lower half of hydranth in a cup-like process; hydranth large, urn-shaped with undercut hypostome, one or more whorls of solid filiform tentacles immediately below it, hydranth body sometimes with basal, tentacle-like protrusion; near base of hydranth epidermal groove from which periderm is secreted, sometimes with a nettle ring immediately above groove; reproduction by fixed sporosacs borne on the hydranth body below the tentacles; reproductive hydranth often reduced to blastostyle, male gonophores usually with several chambers in linear series, female gonophores initially with curved spadix, each spadix holding a single egg.
