Material examined. Stn 67, polysiphonic stem 60 mm high on bryozoan, with male gonothecae, basibiont of Hebella plana (NIWA 117593). Description. Stem 60 mm high, strongly polysiphonic, irregularly branched. Some primary branches also polysiphonic, very long, becoming second-order stems. Secondary stems give rise to other branches, some also distinctly polysiphonic, becoming lower-order stems. Branching up to five-order. Stem and branches divided into internodes by alternately arranged oblique nodes. Internodes slightly arranged in zigzag. Branches typically originating from hydrophores (Fig. 15 C); usually as single branches, although few paired branches, arising from opposite sides of hydrophore, also present.
