Description
While traditionally assumed to have been a member of Dicksoniaceae or a close relative of Thyrsopteris, recent research has reinterpreted it a stem group of Polypodiales.[1] Most species of Coniopteris probably had a herbaceous habit.[1] The genus is technically a junior synonym of the little used Polystichites, but was conserved by the ICZN in 2013.[2]
