Species

Dictyopteridium is an extinct genus of plants belonging to Glossopteridaceae, but the name is used only for compression fossils of elongate multiovulate reproductive structures adnate to Glossopteris leaves.[2] Permineralized remains identical to Dictyopteridium have been referred to the organ genus Homevaleia[3]
