SUMMARY
Pedicellate hydrothecae and erect stems arising from a hydrorhiza creeping on substrate. Hydrorhizal stolons tubular, smooth, perisarc thin, some enclosing sponge spicules. Longer stems monosiphonic, to 6 mm high, junction of stem and hydrorhiza with 9–10 deep annulations; stems with 4–6 widely spaced alternate pedicels, stem internodes long, annulated at base with up to 10 deep rings.
Hydrotheca terminal on a short pedicel held at an acute angle of c. 35° from stem, a slight thickening at junction of stem with pedicel; pedicels annulated throughout. Hydrotheca conical, somewhat variable in length and width, walls smooth, expanding evenly from base to margin, basal chamber distinct, rectangular to quadrangular in shape, merging smoothly into hydrotheca, distal wall of basal chamber a thickened transverse or slightly concave rim, a ring of desmocytes above. Margin of hydrotheca dentate with 10–12 shallow castellated cusps, each cusp shallowly indented.
