Material examined. 50303, one stem 40 mm high, no coppiniae; JC037/019, a stem 50 mm high, no coppiniae. Description. Stems up to 50 mm high, almost completely polysiphonic, and divided into internodes with a distinct zigzag arrangement. Some anastomoses between branches present. Hydrothecae alternately arranged in approximately one plane. Hydrotheca (Fig. 3A) tubular, but curved outwards, particularly at distal part. Diameter roughly constant in free part, but gradually decreasing towards basal part. Free part of adcauline wall distinctly convex; adnate one only slightly convex. Abcauline wall concave at distal third, straight basally. Hydrothecal aperture circular, rim even, sometimes with renovations.
