Cortex commonly diplostichous (1-corticate on some internodes and 3 corticate on some old internodes), strongly tylacanthous. Spine-cells commonly single or in pair, or three together, if so, the third one is short, acute. Spine-cells are densely abundant in young internodes, pointing upwards in the lowest and downwards in the upper part of the internodes. Old internodes have few spine-cells. The spine-cells are as long as the axes diameter, or longer, up to 1.5mmlong. Stipulodes in two tiers, 2 sets per branchlet, short and obscure, missing in many specimens. Branchlets 7-8 in a whorl, 1.2-1.5 cm long, segments 5-6 of which 4-5 are 2-corticate, end segment 2-3-celled, naked. Gametangia on separate plants, at 3-4 lowest branchlet nodes. Female plants: Anterior bract-cells 2, to 1-3 mm long. Posterior bract-cells papillous or short to 100 um long. Bracteoles 2, 1-1.5 mm long. Bractlet as long as the bracteoles.Oogonia 800mlong (ripe?). Oospores black, 700 umlong, 500 um wide, striae of 10 ridges.
