- Diagnosis
- Stems branching dichotomously and pseudomonopodially, 3.5-7.0 mm in diameter, bearing laminar leaves, up to 6.5 mm long, eight to ten per gyre. Leaves with a single vein extending to the tip, divided near the midpoint into a central segment that is approximately 2.5-3.0 mm in length sometimes notched and usually recurred abaxially below the proximal segment, and with two opposite, lateral segments divided near their base; tips variously spread. Stomata scattered on leaves. Xylem a solid strand with 14-18 ridges of protoxylem. Metaxylem scalariform and uni- to triseriate bordered pitted. Leaf traces originate on protoxylem ridges and extend obliquely to leaf bases. Sporophylls similar to vegetative leaves, probably grouped among vegetative leaves along the axis. Sporangia globose to ellipsoidal, attached by a circular pad of tissue to sporophyll just proximal to division of leaf lamina. Stomata on sporangia. Dehiscence is parallel to the midline of the sporophyll. Spores 60-85/~ in diameter exclusive of ornamentation, trilete rays 23-40/1 long, 1-3/a high, connected by curvaturae perfectae which coincide with equator. Equatorial flange bearing spinae 5-9/a long, longest in the radial areas. Biform ornament on proximal and distal surfaces, reduced on proximal. Ornament with basal enlargement (verruca) twice as wide as high, with a tiny projection up to 3/a long and sometimes hooked.
