Taxon discussion

This species is characterized by the conform or subconform apical pinnae, sori medial to supramedial and petioles smooth ( Stolze 1974). The closest species is Cyathea consimilis (Stolze) Lehnert ( Stolze 1974) from which C. subincisa can be distinguished by the smooth or rarely tuberculate petiole (spine or muricate in C. consimilis ).
