- Axes naked. Isotomously or pseudomonopodially branching, with vegetative ultimate tips circinately coiled. Fertile axes naked, dichotomously branching at angles of 25°–55°. Strobili parallel-sided, comprising four rows of oppositely and decussately inserted fertile units; the longest strobilus with more than 60 fertile units; each fertile unit consisting of a sporophyll and an adaxial sporangium. Sporophyll fan-shaped, with a short pedicel, and the laminar region partly enclosing the sporangium. Sporangia elliptical, attached to the adaxial base of the sporophyllous lamina by a short stalk, with distal dehiscence along convex margin. Height of sporophyll lamina and associated sporangium almost equal, 0.8– 1.4 mm. Anatomy unknown.
