- Shoot anisotomously branched. Vegetative leaves dimorphic, arranged in
four ranks, two ranks of smaller ascending median leaves and two other ranks of larger
spreading lateral leaves. Median leaves non-carinate with aristate apex and denticulate to
ciliolate margin. Lateral leaves non-carinate, lanceolate, with acute to acuminate apex and
entire to serrulate to ciliolate margin. Strobili born at apex of the fertile shoots, compact,
tetragonal. Sporophylls arranged in four ranks, monomorphic, with long acuminate apex,
dentate margin, alary serrulate keel.
