- Leaves with pinnules arranged in four rows, two on upper, adaxial side of rachis and two on lower, abaxial side; pinnules of upper rows larger, spread out in one plane, forming an open angle with the rachis, alternate or occasionally subopposite, with fi ne marginal teeth; pinnules in basal part of leaf elliptical and symmetrical with pointed apex; pinnules in middle and upper part of leaf elongate rhomboidal slightly asymmetrical with anadromously positioned tip; pinnules with open dichotomous venation, with three to fi ve veins arising from base, forked one to three times before becoming parallel and reaching margin; pinnules of lower side smaller, directed forward at narrow angles to rachis, basally semiamplexicaulous,
distally dissected into two narrow and long teeth. Strobilus cylinder-like, basally with stalk, sometimes forked apically; sporophylls disk-shaped surrounding cone axis, distal margin dissected into elongate, tapering segments or teeth, each sporophyll with one ring of sessile sporangia on adaxial side; sporangia ellipsoidal with pointed apex; microspores trilete, amb circular to triangular; laevigate exine, rays of trilete mark with labrum; secondary folds of exine present; megaspores with circular to subcircular amb; laevigate exine; secondary folds of exine present; with an equatorial bulge. Strobili and vegetative leaves attached to common axis/stem, forming crown.
