The male reproductive organs of the Cordaitales consisted of elongated clusters of strobili, each strobilus composed of spirally disposed sterile scales and fertile scales, or microsporophylls.
Current views of the relationships were recently summarized by Clement-Westerhof (1988): The Florin view holds that ancient conifers of the Late Pennsylvanian and Early Permian assigned to the Lebachiaceae (Lebachia, Ernesiodendron, and Walchia) evolved from the Cordaitales and were transitional between them and Late Permian and Triassic conifers.
