in height. Largest stems basally polysiphonic. Stem internodes long, limited by slight perisarc constrictions, usually arranged in a marked zigzag. Cauline apophyses far below distal node, forming a large angle with stem. Paired branches divided into long internodes. Paired branches slightly branched. Each paired branch branching at second and seventh internodes, giving rise to secondary branches; first second-order branch usually branching at third internode, forming one tertiary branch that, occasionally, gives rise to one fourth-order branch. Hydrothecae widely separated, alternately arranged in two planes, with strong tendency to unilateral disposition. Hydrotheca cylindrical, slightly curved outwards. Adcauline wall completely free, convex basally, roughly straight distally, as it happens to abcauline wall. Hydrothecal aperture cusps of similar development and separated by shallow embayments. Gonothecae unknown.
