Diagnosis
Frond at least bipinnate. Main rachis straight and strong, about 1.5–2 mm wide, bearing a wing with striking ridge on surface. Pinnae subopposite to alternate, arising at a wide angle from the rachis. Ultimate pinnules small, ca. 3 mm long and 2 mm wide, Pecopteris-like, arising at a right angle from the pinna rachis. Pinnules closely set, margins entire without lobes, catadromic. Basal pair of the lower side pinnules enlarged. Venation delicate but distinct; midrib slightly decurrent, bifurcating and almost disappearing near the apex. Lateral veins fine and distinct, anadromic branching straight or slightly arching, bifurcating once to twice. Fertile pinnae linear to lanceolate, more or less resembling sterile, but more slender. Venation indistinct, secondary veins bifurcating twice. Sporangia closely covering the dorsal surface of pinnules, rounded to oval in shape, about 150–180 µm in diameter.
