Christensenia is a genus of ferns in the botanical family Marattiaceae.
The order Cyatheales, which includes the tree ferns, is a taxonomic division of the fern class, Polypodiopsida.
The word'epidermis' is a single layer of cells that covers the leaves, flowers, roots and stems of plants.
Equisetaceae, sometimes called the horsetail family, is the only extant family of the order Equisetales, with one surviving genus, Equisetum, which comprises about twenty species.
Equisetales is an order of Equisetopsida with only one living family, the Equisetaceae, containing the genus Equisetum (horsetails).
Equisetopsida, or Sphenopsida, is a class of vascular plants with a fossil record going back to the Devonian.
The euphyllophytes are a clade of plants within the tracheophytes (the vascular plants).
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.
The ferns of the order Gleicheniales are – like all ferns and the related horsetails – sometimes placed in an infradivision Monilophytes of subdivision Euphyllophytina, allowing for more precise phylogenetic arrangement of the tracheophytes.
The Hymenophyllaceae (filmy ferns and bristle ferns) are a family of two to nine genera (depending on classification system) Phytotaxa 19: 7-54.
Leptosporangiate ferns are the largest group of living ferns, including some 11000 species worldwide.
The Division Lycopodiophyta (sometimes called lycophyta or lycopods) is a tracheophyte subgroup of the Kingdom Plantae.
The order Marattiales is a group of pteridophyta containing the single family, Marattiaceae.
Marattiidae is a subclass of class Polypodiopsida (ferns).
In cladistics, a monophyletic group, or clade, is a group of organisms that consists of all the descendants of a common ancestor.
Ophioglossaceae, the adder's-tongue family, is a family of ferns (though some studies have instead suggested a closer relationship to angiosperms), currently thought to be most closely related to Psilotaceae, the two together comprising the class Ophioglossidae as the sibling group to the rest of the ferns.
Ophioglossales (lit. 'snake-tongue ') are a small group of pteridophyte plants.
The Osmundaceae (royal fern family) is a family of four to six extant genera and 18–25 known species.
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups.
In biology, phylogenetics (Greek: φυλή, φῦλον – phylé, phylon.
Phytotaxa is a peer-reviewed scientific journal for rapid publication on any aspect of systematic botany.
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae.
The order Polypodiales encompasses the major lineages of polypod ferns, which comprise more than 80% of today's fern species.
Psilotaceae is a family of Pteridophyta (in order Psilotales) consisting of two genera, Psilotum and Tmesipteris with a dozen species.
Psilotopsida is a class of ferns or fern-like plants, considered to be one of the three classes of eusporangiate ferns.
A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores (and lacks seeds).
The order Salviniales (formerly known as the Hydropteridales and including the former Marsileales) is an order of ferns in the class Polypodiopsida.
Schizaeales is an order of fern (class Pteridopsida).
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 biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions.
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.
