Original diagnosis/description

Microsporangiophore consisting of a proximal fertile stalk-like portion and a distal sterile extension. Fertile portion massive with two sporangia deeply sunken in two cavities arranged symmetrically on the presumed abaxial side of the stalk-like portion with one sporangium in each cavity. Dehiscence of sporangium by a longitudinal slit facing the opening of the cavity. Sterile distal tip of sporangiophore elongate, conical, tapering distally to a slender point. Cuticle thick; stomata on distal tip haplocheilic, deeply sunken. Pollen monocolpate, tectate-psilate.
