  supertype:  gymnosperm_family  a family of gymnosperms
  member:  genus_Cordaites
  member of:  order_Cordaitales__Cordaitales  extinct plants having tall arborescent trunks comparable to or more advanced than cycads; known from the Pennsylvanian; probably extinct since the Mesozoic
     member of:  class_Coniferopsida__Coniferopsida__Coniferophytina__subdivision_Coniferophytina__Coniferophyta  cone-bearing gymnosperms dating from the Carboniferous period; most are substantial trees; includes the classes Pinopsida (subdivision Pinophytina) and Ginkgopsida (subdivision Ginkgophytina) and Taxopsida (subdivision Taxophytina) which in turn include the surviving orders Coniferales and Taxales (yews) and sometimes Ginkgoales as well as extinct orders such as Cordaitales (of the Carboniferous and Permian)
        member of:  class_Gymnospermae__Gymnospermae__Gymnospermophyta__division_Gymnospermophyta  plants having naked seeds not enclosed in an ovary; in some systems considered a class (Gymnospermae) and in others a division (Gymnospermophyta); comprises three subdivisions (or classes): Cycadophytina (class Cycadopsida) and Gnetophytina (class Gnetopsida) and Coniferophytina (class Coniferopsida); in some classifications the Coniferophytina are divided into three groups: Pinophytina (class Pinopsida) and Ginkgophytina (class Ginkgopsida) and Taxophytina (class Taxopsida)
           member of:  division_Spermatophyta__Spermatophyta  seed plants; comprises the Angiospermae (or Magnoliophyta) and Gymnospermae (or Gymnospermophyta); in some classification systems Spermatophyta is coordinate with Pteridophyta (spore producing plants having vascular tissue and roots) and Bryophyta (spore producing plants lacking vascular tissue and roots)
