Internodes moderately long (185–260 µm), basal-most comparatively longer than following ones; each with bulges at both ends; a short (25–35 µm) apophysis borne on distal half of internode, supporting alternate hydrophores, and a nematotheca above axil formed by apophysis with stem. Hydrophores of variable length, funnel-shaped, carrying distally a hydrotheca (150–245 µm long, including hydrotheca); diaphragm not observed, rim even, margin flaring, 135–145 µm wide.
