Alligator

An alligator, or colloquially gator, is a large reptile in the genus Alligator of the family Alligatoridae of the order Crocodilia.

See Lepidodendrales and Alligator

Apomorphy and synapomorphy

In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy).

See Lepidodendrales and Apomorphy and synapomorphy

Archaeopteris

Archaeopteris is an extinct genus of progymnosperm tree with fern-like leaves. Lepidodendrales and Archaeopteris are Carboniferous plants.

See Lepidodendrales and Archaeopteris

Bark (botany)

Bark is the outermost layer of stems and roots of woody plants.

See Lepidodendrales and Bark (botany)

Biological carbon fixation

Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide) to organic compounds.

See Lepidodendrales and Biological carbon fixation

Biomass

Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms.

See Lepidodendrales and Biomass

Chert

Chert is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2).

See Lepidodendrales and Chert

Compression fossil

A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression.

See Lepidodendrales and Compression fossil

Cork cambium

Cork cambium (cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis.

See Lepidodendrales and Cork cambium

Cortex (botany)

In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles.

See Lepidodendrales and Cortex (botany)

Crown (botany)

The crown of a plant is the total of an individual plant's aboveground parts, including stems, leaves, and reproductive structures.

See Lepidodendrales and Crown (botany)

Cuticle

A cuticle, or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection.

See Lepidodendrales and Cuticle

Gametophyte

A gametophyte is one of the two alternating multicellular phases in the life cycles of plants and algae.

See Lepidodendrales and Gametophyte

Glossopteris (etymology: from Ancient Greek γλῶσσα (glôssa, " tongue ") + πτερίς (pterís, " fern ")) is the largest and best-known genus of the extinct Permian order of seed plants known as Glossopteridales (also known as Arberiales, Ottokariales, or Dictyopteridiales).

See Lepidodendrales and Glossopteris

Guadalupian

The Guadalupian is the second and middle series/epoch of the Permian.

See Lepidodendrales and Guadalupian

Heterospory

Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants.

See Lepidodendrales and Heterospory

Indeterminate growth

In biology and botany, indeterminate growth is growth that is not terminated in contrast to determinate growth that stops once a genetically predetermined structure has completely formed.

See Lepidodendrales and Indeterminate growth

Isoetales

Isoetales, sometimes also written Isoëtales, is an order of plants in the class Lycopodiopsida.

See Lepidodendrales and Isoetales

Isoetes

Isoetes, commonly known as the quillworts, is a genus of lycopod.

See Lepidodendrales and Isoetes

Leaf

A leaf (leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis.

See Lepidodendrales and Leaf

Lepidodendron

Lepidodendron is an extinct genus of primitive lycopodian vascular plants belonging the order Lepidodendrales. Lepidodendrales and Lepidodendron are Prehistoric lycophytes.

See Lepidodendrales and Lepidodendron

Ligule

A ligule (from "strap", variant of lingula, from lingua "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (family Poaceae) and sedges (family Cyperaceae).

See Lepidodendrales and Ligule

Lycopodiaceae

The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) are an old family of vascular plants, including all of the core clubmosses and firmosses, comprising 16 accepted genera and about 400 known species.

See Lepidodendrales and Lycopodiaceae

Lycopodiopsida

Lycopodiopsida is a class of vascular plants also known as lycopods or lycophytes.

See Lepidodendrales and Lycopodiopsida

Meristem

In cell biology, the meristem is a type of tissue found in plants.

See Lepidodendrales and Meristem

Moulting

In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in its life cycle.

See Lepidodendrales and Moulting

Phloem

Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant.

See Lepidodendrales and Phloem

Pith

Pith, or medulla, is a tissue in the stems of vascular plants.

See Lepidodendrales and Pith

Plant

Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic.

See Lepidodendrales and Plant

Sclerophyll

Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat.

See Lepidodendrales and Sclerophyll

Selaginella

Selaginella is the sole genus in the monotypic family (i.e. a family that contains only a single genus) Selaginellaceae, the spikemosses or lesser clubmosses, a type of vascular plant.

See Lepidodendrales and Selaginella

Sigillaria

Sigillaria is a genus of extinct, spore-bearing, arborescent lycophyte, known from the Carboniferous and Permian periods. Lepidodendrales and Sigillaria are Carboniferous first appearances and Prehistoric lycophytes.

See Lepidodendrales and Sigillaria

Sporangium

A sporangium (from Late Latin);: sporangia) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other groups form sporangia at some point in their life cycle. Sporangia can produce spores by mitosis, but in land plants and many fungi, sporangia produce genetically distinct haploid spores by meiosis.

See Lepidodendrales and Sporangium

Sporophyll

A sporophyll is a leaf that bears sporangia.

See Lepidodendrales and Sporophyll

Stele

A stele,From Greek στήλη, stēlē, plural στήλαι stēlai; the plural in English is sometimes stelai based on direct transliteration of the Greek, sometimes stelae or stelæ based on the inflection of Greek nouns in Latin, and sometimes anglicized to steles.) or occasionally stela (stelas or stelæ) when derived from Latin, is a stone or wooden slab, generally taller than it is wide, erected in the ancient world as a monument.

See Lepidodendrales and Stele
