Hydrocaulus monosiphonic, unbranched or sparingly branched, annulated at insertion with hydrorhiza, divided into internodes of varying length by distinct nodes, older hydrocauli of larger plumes straight basally, with 1-4 internodes bearing neither branches nor hydrothecal pedicels, geniculate beyond basal region, with internodes annulated basally or throughout, annulations strongest over proximal end, each internode widening at distal end in form of a Y and bearing two apophyses, with one apophysis supporting internode above and the other supporting a hydrophore or a branch, branches or hydrophores given off alternately from opposite sides of hydrocaulus. Perisarc mostly quite thin and glassy. Branches, when present, resembling distal parts of hydrocaulus. Young hydrophores with a swelling or an annulation or two above a basal node separating them from apophysis of hydrocaulus, occasionally with a deep constriction proximally, slightly wrinkled or smooth and gradually widening distally, bearing a terminal hydrotheca or primary hydrotheca; a pseudodiaphragm sometimes evident on hydrophore just below hydrotheca, with its development greater on the adcauline side; primary hydrophores commonly supporting shorter secondary or tertiary ones arising from diaphragm of hydrotheca below.
