The Carboniferous medullosalean pteridosperm Havlenaea praeovata (Němejc) Šimůnek
Šimůnek Zbyněk | Cleal Christopher J.
A study of Ettingshausen’s type material of Neuropteris coriacea stored in the Geologisches Bundesanstalt in Vienna has demonstrated that they are conspecific with Havlenaea praeovata (Němejc) Šimůnek & Cleal (Carboniferous medullosalean pteridosperm). Because of priority, the epithet coriacea must take precedence, and a new combination is proposed: Havlenaea coriacea (Ettingshausen) Šimůnek & Cleal, comb. nov.
