Diagnosis Colonies stolonal or erect, arising from creeping hydrorhiza; hydrocauli monosiphonic or polysiphonic; hydrothecae shallow to bell-shaped, sessile or pedicellate, basal region with delicate diaphragm, with or without desmocytes; hydranths usually much larger than hydrothecae, with or without an intertentacular web. Nematophores present, with variably reduced nematothecae. Gonophores fixed sporosacs; gonothecae solitary or aggregated to form a glomulus [details]
