Emended diagnosis. Colony with upright hydrocaulus, monosiphonic, erect, slightly zigzag, unbranched or branched, hydrocladia usually originate from within the hydrothecal cavity, sometimes directly growing on hydrocaulus beneath a hydrotheca, without axillary hydrotheca, without stem apophysis. With regular and oblique nodes, each internode bearing a hydrotheca. Hydrothecae alternately arranged in two rows almost in one plane, or forming an angle less than 90º, sometimes spirally arranged in three longitudinal rows; hydrotheca tubular, partly adnate, with three marginal cusps, one adcauline and two lateral abcauline, and three operculum flaps forming a pyramid; retracted hydranth with poorly developed abcauline caecum. Clinging organ present, resembling bubbly lobes. Gonotheca generally originate from within the hydrothecal cavity or growing directly from hydrocaulus, pedicellate, with a short distal neck, sexually dimorphic. Nematocyst capsule spindle-shaped, microbasic mastigophores.
