- Plant with creeping axes, from which arise vegetative and fertile axes. Vegetative axes bearing lateral appendages in a helical arrangement; lateral appendages dichotomous, with curved, acuminate or round tips. Fertile axes terminated by strobili, which comprise fertile units arranged in irregular helices. Each fertile unit generally long-ovate in abaxial view, comprising a sporangium and two discrete bracts; sporangium being covered by two bracts from above and below directions. Sporangia stalked, long-elliptical in abaxial view, dehiscing along the whole margin into two equal valves.
