Description . Hydrorhiza reptant, giving off pedicellate hydrothecae at irregular intervals. Pedicels slender (50–70 µm wide) and of varied length (155–730 µm), either unbranched or sparingly and irregularly branched once or twice; perisarc spirally grooved, slightly widening distally and merging smoothly into hydrotheca; pedicel and hydrotheca delimited by delicate "diaphragm". Hydrothecae 360–560 µm long, lateral walls slightly divergent, widest (110–160 µm) at opercular base; operculum membranous, conical, pleated, not delimited basally by crease line. Gonothecae absent. Remarks . The sterile condition of the present material prevent us from providing a reliable identification for this species.
