Description
Plants dioecious, to 20cm high, medium to heavily incrusted. Axes moderately stout,
to 1mm in diameter. Internodes 1-3 times as long as the branchlets, which are 1.2-1.5 cm
long. 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.
Male plants: Bracteoles 2, anterior bract-cells 2 (not developed in all plants), as long as
or shortly longer than the antheridia. Bractlet not seen. Antheridia 600-750 um in diameter.
