Internodes moderately long, width increasing imperceptibly towards distal ends, so as to accommodate the basal part of a hydrotheca. Branching scarce and irregular, in one plane, with up to 2

order branches observed; side branches originating laterally from below the base of a stem hydrotheca; first internode comparatively longer than subsequent ones, constricted basally at insertion on stem; remainder of side branches with similar structure as the stem. Hydrothecae arranged alternately at an angle of 35–40° with the internode; moderately long, tronconical, widening slightly below aperture; adaxial wall adnate for about ½ its length; free part with 4–5 transverse, though incomplete, ridges, not reaching abaxial side, running parallel to adnate side of adaxial wall; abaxial wall nearly straight; margin occasionally renovated; aperture quadrate in frontal view, bearing 4 short cusps separated by shallow embayments; five prominent, submarginal, intrathecal cusps: two latero-adaxial, two latero-abaxial, and one abaxial. Gonothecae originating from the internode, on side opposite hydrotheca, midway between its base and proximal node; large, transversely ribbed; a short, distal neck; aperture large, surrounded by 3–4 almost imperceptible, blunt cusps; a few large oocytes noticeable by transparency.
