Monosiphonic, unbranched stems, up to 100 mm high, divided into internodes. Cauline apophyses with two axillary nematophores, each emerging through simple hole in perisarc (Fig. 15 B). Hydrocladia usually bifurcated, first hydrocladial internode giving rise to two secondary hydrocladia; however, a third-order hydrocladium is not uncommon (Fig. 15 A). First hydrocladial internode bifurcated, with two similar prongs (Fig. 15 A). Mesial inferior nematophore emerging from marked swelling at proximal third of internode (Fig. 15 C); with well-developed, claw-shaped nematotheca (Fig. 15 C–E). Hydrotheca low, about as high as wide, placed on distal half of internode. Abcauline wall straight; adcauline one mostly adnate (Fig. 15 C). Hydrothecal aperture circular (Fig. 15 D), roughly ... : Published as part of Molinero, A. González & Peña Cantero, A.
