Polysiphonic, branched stems up to 120 mm high. Stems not divided into internodes, with two longitudinal series of cauline apophyses. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with two axillary nematophores, each emerging through a simple hole in perisarc (Fig. 6B); no ‘mamelons’ present. Hydrocladia bifurcated (Fig. 6A), only hydrocladia of second order present. Secondary hydrocladia distinctly bent inwards.

Mesial-inferior nematophore emerging from a swelling at proximal third of internode (Fig. 6C–E), and provided with a reduced claw-shaped nematotheca (Fig. 6C–E); first hydrocladial internode frequently without nematophore (Fig. 6B). Hydrotheca placed on distal half of internode (Fig. 6A, C–D). Hydrotheca low, about as high as wide (Fig. 6A, C–D). Abcauline hydrothecal wall straight, but distinctly directed outwards (Fig. 6D). Hydrothecal aperture circular, perpendicular to longitudinal axis of internode (Fig. 6C) or leaned adcaudally (Fig. 6D); rim even (Fig. 6C–D).
