From editor or global species database
Diagnosis Colony usually erect, monosiphonic or polysiphonic, branched or unbranched, arising from a creeping hydrorhiza, stem and branches divided in internodes bearing apohyses near distal end; hydrothecae alternate, sessile or pedicellate, borne on apophyses when not pedicellate, shallow; rim commonly everted and regenerated; a ring of large desmocytes and a basal diaphragm; hydranth not retractable into hydrotheca, often with an annular bugle half way up the gastric column; intertentacular web present or not; nematotheca and nematophores absent; gonophores as fixed sporosacs in gonothecae sometimes with acrocyst, gonothecae either solitary or aggregated to form a glomulus, usually sexually dimorphic, sometimes with gonophoral polyps or arising from within hydrothecae; typically sexually dimorphic.
