Hydrocauli monosiphonic, divided into internodes by oblique nodes visible only towards apical end. Each internode with one or two apophyses and one to three nematothecae between two consecutive apophyses. Apophyses arranged alternately left and right in one plane in older parts of branches; younger parts with apophyses occurring left and right but almost in a single frontal row; each apophysis with a well developed mamelon on upper surface and with two axillary nematothecae, an extra distal nematotheca appearing on some apophyses; one perisarcal ring often present near node. Hydrocladia heteromerously segmented, beginning with a short ahydrothecate internode having one nematotheca on basal part and two internal perisarcal rings near proximal and distal ends; nematotheca of first internode sometimes lost. Remainder of hydrocladia divided into alternating hydrothecate and ahydrothecate internodes by oblique nodes. Each hydrothecate internode bearing a hydrotheca and three nematothecae: one mesial inferior on an elevation, and two laterals located on short apophyses. Hydrothecae tubular, deep, narrowing towards base, adcauline wall fully adnate, abcauline wall slightly sinuous with basal half slightly convex and distal half slightly concave; hydrothecal rim smooth, circular, slightly tilted toward abcauline wall. Ahydrothecate internodes each with one nematotheca on an elevation along basal third. All nematothecae movable, bithalamic, conical; mesial inferior nematotheca with adcauline wall of upper chamber somewhat deeper than usual and emarginated. Internodes with two perisarcal rings, one at each end, sometimes an additional thickening appearing below, behind or above hydrotheca.
