The ferns are a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase.
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials.
Matteuccia is a genus of ferns with one species: Matteuccia struthiopteris. The species epithet struthiopteris comes from Ancient Greek words στρουθίων (strouthíōn) "ostrich" and πτερίς (pterís) "fern".
Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.
Volubilis is a partly-excavated Berber-Roman city in Morocco situated near the city of Meknes that may have been the capital of the Kingdom of Mauretania, at least from the time of King Juba II. Before Volubilis, the capital of the kingdom may have been at Gilda.
Blechnaceae is a family of ferns in the order Polypodiales, with a cosmopolitan distribution. Its status as a family and the number of genera included have both varied considerably. In the Pteridophyte Phylogeny Group classification of 2016, the family has 24 genera, and excludes genera placed in the separate family Onocleaceae. The family is divided into three subfamilies, including Blechnoideae s.s. Alternatively, the entire family may be treated as the subfamily Blechnoideae s.l. of a very broadly defined family Aspleniaceae, and include genera others place in Onocleaceae.
Asplenium scolopendrium, commonly known as the hart's-tongue fern, is an evergreen fern in the family Aspleniaceae native to the Northern Hemisphere.
Azolla filiculoides is a species of Azolla, native to warm temperate and tropical regions of the Americas which was introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii.
Struthiopteris spicant, syn. Blechnum spicant, is a species of fern in the family Blechnaceae, known by the common names hard-fern or deer fern. It is native to Europe, western Asia, northern Africa, and western North America. Like some other species in the family Blechnaceae, it has two types of leaves. The sterile leaves have flat, wavy-margined leaflets 5 to 8 millimeters wide, while the fertile leaves have much narrower leaflets, each with two thick rows of sori on the underside.
Microgramma is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are commonly known as vine ferns or snakeferns.
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that do not contain chlorophyll, and obtain their energy from other plants.
Salpichlaena is a genus containing two species of fern in the family Blechnaceae. Species of the genus are native to Central and South America. These ferns have climbing leaves with a rachis that twines around tree branches and other supports.
Rumohra adiantiformis, the leather fern or leatherleaf fern, is a species of fern in the wood fern family Dryopteridaceae. It has a wide distribution, mainly in the tropical Southern Hemisphere.
Petrea volubilis, commonly known as purple wreath, queen's wreath or sandpaper vine, is an evergreen flowering vine in the family Verbenaceae, native to Tropical America, that is valued especially for its display of violet flowers.
Tryonia is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to the east of Brazil and to Uruguay.
Hemionitis is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. Its circumscription varies greatly in different systems of fern classification. In the Pteridophyte Phylogeny Group classification of 2016, it was one of more than 20 genera in the subfamily Cheilanthoideae, and was said to have five species. Other sources treat it as the only genus in the subfamily, and so accept about 450 species. With the restricted circumscription, species are native to tropical America.
Olfersia is a genus of ferns in the family Dryopteridaceae, subfamily Polybotryoideae, in the Pteridophyte Phylogeny Group classification of 2016. They are found in Mexico and parts of South America.
Chrysophyllum gonocarpum is a tree in the family Sapotaceae, native to South America.
Moquilea tomentosa is a species of flowering plant in the family Chrysobalanaceae, native to most of Brazil. It is widely cultivated for its abundant fruit in South America and South Africa, and it is used as a street tree in Brazil and Colombia.
