Sceptridium is a genus of seedless vascular plants in the family Ophioglossaceae, closely allied to the genus Botrychium. It is also closely related to the genus Botrypus. Sceptridium species are commonly called the grape-ferns.
Chamaenerion angustifolium is a perennial herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb. In the United Kingdom it is also known as bombweed, as a result of its rapid appearance on city bomb sites during the Blitz of World War II; the plant is also traditionally known as Saint Anthony's laurel. It is also known by the synonyms Chamerion angustifolium and Epilobium angustifolium. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.
Ophioglossum vulgatum, commonly known as adder's-tongue, southern adders-tongue or adders-tongue fern, is a species of fern in the family Ophioglossaceae.
The order Polypodiales encompasses the major lineages of polypod ferns, which comprise more than 80% of today's fern species. They are found in many parts of the world including tropical, semitropical and temperate areas.
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial.
Polystichum is a genus of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus has about 500 species and has a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 208 species in China alone; the region from Mexico to Brazil has at least 100 additional species; Africa, North America, and Europe have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions. They are often found in disturbed habitats such as road cuts, talus slopes, and stream banks.
Athyrium filix-femina, the lady fern or common lady-fern, is a large, feathery species of fern native to temperate Asia, Europe, North Africa, Canada and the USA. It is often abundant in damp, shady woodland environments and is often grown for decoration.
Vaccinium angustifolium, commonly known as the wild lowbush blueberry, is a species of blueberry native to eastern and central Canada and the northeastern United States, growing as far south as the Great Smoky Mountains and west to the Great Lakes region. Vaccinium angustifolium is the most common species of the commercially used wild blueberries and is considered the "low sweet" berry.
Phlebodium aureum is an epiphytic fern native to tropical and subtropical regions of the Americas.
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.
Sisyrinchium angustifolium, commonly known as narrow-leaf blue-eyed-grass, is a herbaceous perennial growing from rhizomes, native to moist meadow and open woodland. It is the most common blue-eyed grass of the eastern United States, and is also cultivated as an ornamental.
Guaiacum angustifolium is a species of flowering plant in the caltrop family, Zygophyllaceae. Common names include Texas guaiacum, Texas lignum-vitae, soapbush and huayacán. It is native to southern and western Texas in the United States and northern Mexico. The specific name is derived from the Latin angustus, meaning "narrow," and -folius, meaning "-leaved".
Chlorogalum angustifolium is a species of flowering plant, known by the common name narrowleaf soap plant.
Diplazium is a genus of ferns that specifically includes the approximately 400 known species of twinsorus ferns. The Greek root is diplazein meaning double: the indusia in this genus lie on both sides of the vein. These ferns were earlier considered part of either the Athyriaceae, Dryopteridaceae, Aspleniaceae, or Polypodiaceae families or recognized as belonging to their own taxonomic family. The Pteridophyte Phylogeny Group classification of 2016 places the genus in the Athyriaceae. The taxonomy of the genus is difficult and poorly known, and by 2009 has never been the subject of a complete monographic study. Their distribution is pantropical, with a few species extending into temperate areas.
Homalosorus is a genus of fern with only one species, Homalosorus pycnocarpos. It may also be referred to by its older synonyms Athyrium pycnocarpon and Diplazium pycnocarpon. Commonly referred to as the narrow-leaved glade fern, narrow-leaved-spleenwort, or glade fern, it is endemic to eastern North America and typically grows in moist woodlands. Once classified in the family Athyriaceae due to its linear, often doubled sori, in the Pteridophyte Phylogeny Group classification of 2016, it is placed in the small family Diplaziopsidaceae, whose other three species are native to east Asia. Other sources place the genus in the subfamily Diplaziopsidoideae of a very broadly defined family Aspleniaceae, equivalent to the suborder Aspleniineae in PPG I.
Camplyoneurum xalapense is a species of fern in the family Polypodiaceae. It is apparently found only within Central America, especially in southern Mexico and Guatemala.
Trifolium angustifolium is a species of clover known by the common names narrowleaf crimson clover, narrow clover and narrow-leaved clover.
Campyloneurum phyllitidis, commonly known as the long strap fern, is a species of fern in the family Polypodiaceae.
Polypodioideae is a subfamily belonging to the fern family Polypodiaceae, which is a member of the suborder Polypodiineae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the subfamily may be treated as the tribe Polypodieae within a very broadly defined family Polypodiaceae sensu lato.
Polypodium is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek poly (πολύ) "many" + podion (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypodies or rockcap ferns, but for many species unique vernacular names exist.
