high, arising from creeping, branched, anastomozing, hydrorhiza; no stolonal nematothecae. Basal part with one or more athecate internodes of varied length, sometimes with signs of breakage and subsequent regeneration; nodes transverse except distalmost, which is oblique; nematothecae, variable in number, in two frontal, parallel rows. Distal, much longer part of stems, composed of alternating hydrothecate and ahydrothecate segments; segmentation heteromerous. Hydrothecate segments, as much as twelve per erect shoot, with oblique nodes proximally and transverse nodes distally; 195–230 µm long; with one hydrotheca placed towards distal end and four nematothecae: one mesial, a pair of laterals, and one axilar. Hydrotheca cup-shaped, axis oblique to that of internode; adcauline wall straight and adnate for about twothirds of length, free part 60–65 µm long; abcauline wall 115–130 µm long, slightly sigmoid, concave basally and convex below rim. Margin entire, slightly flaring, perpendicular to long axis of hydrotheca, 140–155 µm wide. Ahydrothecate segments with transverse proximal node (40–45 µm wide) and oblique distal node; comparatively longer (230–620 µm) than hydrothecate segments; with 3–8 frontal, alternate nematothecae in two parallel rows. All nematothecae bithalamic, basal chamber deeper than upper chamber; all movable except mesial and possibly axillar ones; all with lowered rim on adaxial side of upper chamber. Axillar nematothecae placed centrally, just behind adcauline wall of corresponding hydrothecae. Gonothecae pearshaped, 335–350 µm long,
