Stem polysiphonic composed by several secondary axial tubes along all extension, decreasing number distally; stem and hydrocladia with distinct apophyses budding off obliquely upwards in relation to main axis, in several planes (Pl. 3A); variable number of free hydrothecae between each pair of sub-opposite hydrocladia. Hydrocladia rectilineous attached to stem without apophysis, arising at angles 65°–70° in relation to stem; few irregular nodes/internodes observed, slightly oblique on main axial tube and on distal region of hydrocladia; some hydrocladia covered by secondary tubes with nematothecae and scar at insertion; weakly polysiphonic at proximal region, stem monosiphonic distally. Hydrothecae tubular, adcauline wall slightly convex, abcauline wall slightly concave (Pl. 3B); rim without renovations; diaphragm as thickened oblique perisarcal ring; pedicel from smooth to wrinkled at different degrees, sometimes with distinct annulations (Pl. 3B–C). Nematothecae pedicellated, on hydrothecal apophysis and secondary axial tubes, cylindrical to tubular, with constriction on proximal third (Pl. 3D); nematotheca on hydrothecal apophysis long, surpassing level of hydrothecal diaphragm. Gonosome aggregated into coppinia, thin gonothecae in dense clusters, distal part with free tubular processes pointing obliquely upwards, each process with one elliptical aperture; nematophorous tubules projecting among gonothecae with nematothecae and hydrothecae.
