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. The later were intermixed with the sterile scales or confined to the apex of the axis of the dwarf shoot.
For example, Canright (1952) states that he regards the broad expanded types of microsporophylls found in certain Ranalian families as relatively unmodified fertile phyllomes--that is, presumably, fertile leaves or leaf-like organs.
microsporophyll. Older plants develop a slender, often decumbent, aerial
microsporophyll. It is nearest to Cycas chevalieri and C.
The microsporophylls within this compact structure are peltate or apically thickened, a distinctive feature of the Taxaceae and the Cephalotaxaceae but also present in the Araucariaceae.
The Taxaceae are distinguished from other conifer families (except for Cephalotaxaceae) by compound pollen strobili or simple structures derived from compound pollen strobili, peltate microsporophylls, and solitary, terminal ovules embedded in a fleshy closed or open aril.
