Describe a late-Devonian, Honggulleng Formation in Xinjiang and the Bouksay, a Lycopodium sp. Capsulosa that diverges once and divergently, with long spindle-shaped leaf bases closely coiled on the cob, each 6 rounds; spore leaves lanceolate, petioles, single veins, margin with serrated teeth; sporangia paraaxially at birth, elongated ellipsoid, capsule has 4 megaspores; megaspore spherical, smooth surface, Diameter 90 0-1200 μm. Through comparative studies, the current sporangium was identified as a new genus, a new species, Hefengistrobusbifurcusgen. Etap. Nov., And discussed the significance of the sporangium in the evolution of the Lycoris.
