In biological classification, class (classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank.
A cone (in formal botanical usage: strobilus, plural strobili) is an organ on plants in the division Pinophyta (conifers) that contains the reproductive structures.

A cryptogam (scientific name Cryptogamae) is a plant (in the wide sense of the word) that reproduces by spores, without flowers or seeds.
Cycads are seed plants with a long fossil history that were formerly more abundant and more diverse than they are today.
The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya.
Douglas Soltis is a Distinguished Professor in the Laboratory of Molecular Systematics & Evolutionary Genetics, (Soltis lab.) Florida Museum of Natural History and Department of Biology at the University of Florida.
The Embryophyta are the most familiar group of green plants that form vegetation on earth.
Ephedra is a genus of gymnosperm shrubs, the only genus in its family, Ephedraceae, and order, Ephedrales.
In biology, extinction is the termination of an organism or of a group of organisms (taxon), normally a species.
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approximately 13,164 known genera and c. 295,383 known species.
In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering.
Ginkgo is a genus of highly unusual non-flowering plants.
Ginkgoales or Ginkgophyte is a gymnosperm order containing only one extant species: Ginkgo biloba, the ginkgo tree.
Glossopteris (γλώσσα glossa, meaning "tongue", because the leaves were tongue-shaped, and pteris, Greek for fern or feathery) is the largest and best-known genus of the extinct order of seed ferns known as Glossopteridales (also known as Arberiales or Ottokariales).
Gnetophyta is a division of plants, grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: Gnetum (family Gnetaceae), Welwitschia (family Welwitschiaceae), and Ephedra (family Ephedraceae).
Gnetum is a genus of gymnosperms, the sole genus in the family Gnetaceae and order Gnetales.
Gondwana, or Gondwanaland, was a supercontinent that existed from the Neoproterozoic (about 550 million years ago) until the Carboniferous (about 320 million years ago).
Greek (Modern Greek: ελληνικά, elliniká, "Greek", ελληνική γλώσσα, ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean and the Black Sea.
The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes.
The Holocene is the current geological epoch.
In biology, integument is the natural covering of an organism or an organ, such as its skin, husk, shell, or rind.
The Lyginopteridales were the archetypal pteridosperms: They were the first plant fossils to be described as pteridosperms and, thus, the group on which the concept of pteridosperms was first developed;Oliver, F. W. & Scott, D. H. (1904).
Magnoliopsida is a valid botanical name for a class of flowering plants.
The Paleozoic (or Palaeozoic) Era (from the Greek palaios (παλαιός), "old" and zoe (ζωή), "life", meaning "ancient life") is the earliest of three geologic eras of the Phanerozoic Eon.
Pamela Soltis is an American botanist.
The Permian is a geologic period and system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic period 251.902 Mya.
In biology, a phylum (plural: phyla) is a level of classification or taxonomic rank below Kingdom and above Class.
The Pinaceae (pine family) are trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, larches, pines and spruces.
The Pinophyta, also known as Coniferophyta or Coniferae, or commonly as conifers, are a division of vascular land plants containing a single extant class, Pinopsida.
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae.
Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, enabling later fertilisation and the production of seeds, most often by an animal or by wind.
Proceedings of the National Academy of Sciences of the United States of America (PNAS) is the official scientific journal of the National Academy of Sciences, published since 1915.
The term Pteridospermatophyta (or "seed ferns" or "Pteridospermatopsida") refers to several distinct groups of extinct seed-bearing plants (spermatophytes).
Runcaria heinzelinii is an extinct species of plant from the Middle Devonian of Belgium.
A seed is an embryonic plant enclosed in a protective outer covering.
The spermatophytes, also known as phanerogams or phenogamae, comprise those plants that produce seeds, hence the alternative name seed plants.
A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) ‘spore’ + αγγείον (angeion) ‘vessel’) is an enclosure in which spores are formed.
In linguistics, a suffix (sometimes termed postfix) is an affix which is placed after the stem of a word.
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.
The Triassic is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.9 million years ago (Mya), to the beginning of the Jurassic Period Mya.
Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea) and also higher plants, form a large group of plants (c. 308,312 accepted known species) that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant.
A vessel element or vessel member (trachea) is one of the cell types found in xylem, the water conducting tissue of plants.
Welwitschia is a monotypic gymnosperm genus, comprising solely the distinctive Welwitschia mirabilis.
