Diagnosis Plumulariid hydroids having an erect, polysiphonic, branched or unbranched main axis lacking apophyses and hydrocladia except at proximal end, main axis geniculate, at least in younger parts of colony. Tubes of main axis giving rise to ultimate branches, equivalent to hydrocauli. Primary axial tube at base of main axis with apophyses and hydrocladia, giving rise to secondary axial tubes before diverging laterally from main axis to form first ultimate branch (proximalmost hydrocaulus of colony). As with primary axial tube, secondary axial tubes giving rise to new secondary axial tubes before diverging laterally from main axis, and so on; apophyses and hydrocladia absent on all axial tubes beyond the primary one. Hydrorhiza where known a root-like mass of intertwining tubules adhering to sandy sediment. Ultimate branches equivalent in morphology to hydrocauli of Plumularia in being monosiphonic, unbranched, and divided into internodes with varied numbers of alternate apophyses bearing hydrocladia. Hydrocladia unbranched, borne only on ultimate branches and at base of primary axial tube, divided into homomerously or heteromerously segmented internodes. Hydrothecate internodes of hydrocladia each with a hydrotheca, a pair of lateral nematothecae, and one or more median inferior nematothecae. Ahydrothecate internodes of hydrocladia, when present, with one or more median nematothecae each. Hydrothecae occurring only on hydrocladia, uniseriate, small, cup-shaped, adnate to internode, margin smooth. Nematothecae conical, bithalamic, movable.  [details]
