Ahydrothecate internodes comparatively longer than their hydrothecate counterparts, with proximal node transverse and distal node oblique; first internode exceedingly long, with 4–6 frontal nematothecae in row, subsequent ones shorter and provided with 2 frontal nematothecae, length of internodes decreasing distally, so that only 1 nematotheca is to be found on them. Hydrothecate internodes with proximal node oblique and distal node transverse, with one hydrotheca and its three associated nematothecae: a mesial one, not reaching the hydrothecal base, and pair of relatively short laterals, borne on moderately-long apophyses, together reaching half-length the adnate wall of hydrotheca. Hydrothecae very deep, tubular, somehow flared at margin, rim circular, entire. Gonothecae borne on cladia, given off singly from lateral side of hydrothecate internode, between hydrothecal basis and mesial nematotheca; pedicel of two short, quadrangular, athecate segments; gonotheca large, piriform, thin-walled, tapering basally and provided there with 3 nematothecae; aperture apical, ovoid, provided with watch-glass-shaped operculum. All nematothecae bithalamic, conical, upper chamber shorter than basal one, with rim scooped on both ab- and adaxial sides, distinctly more on the latter.
