Taxon discussion

This species is a putative hybrid between Thelypteris (Goniopteris) tetragona (Sw.) Small and T. (Goniopteris) poiteana (Bory) Proctor ( Smith 1983). It can be characterized by the pinnae serrulate to shallowly lobed or incised to 1/3 the distance to costae, 2-3 pairs of basal veins anastomosing below sinus, and the presence of several hairs on sporangial capsule ( Smith 1983).
