- Plant consisting of main axes attached to a possible rhizome and bearing alternately arranged lateral branching systems. Sterile lateral branching systems bilaterally symmetrical, up to six times dichotomously branched, with all divisions occurring in the same plane, and almost no overlapping between any segments; distal segments being possibly slightly flattened and/or webbed. Fertile lateral branching systems six times dichotomous, with last axis segments bearing one pair of sporangia. Sporangia fusiform, pendulous and twisted anticlockwise from bottom to top around each other in
each pair; tip of the sporangium acute, sometimes beak-like. Spores
and anatomy unknown.
