Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), 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.

Arrhenatherum elatius is a species of flowering plant in the grass family Poaceae, commonly known as false oat-grass, and also bulbous oat grass (subsp. bulbosum), tall oat-grass, tall meadow oat, onion couch and tuber oat-grass. It is native throughout Europe (including Iceland), and also western and southwestern Asia (south to Jordan and Iran), and northwestern Africa (Morocco to Tunisia). This tufted grass is sometimes used as an ornamental grass and is sometimes marketed as "cat grass". Outside of its native range it can be found elsewhere as an introduced species. It is found especially

Spergularia is a genus in the family Caryophyllaceae, containing salt-tolerant plants known as sandspurrys (or sandspurries) and sea-spurreys. There are about 60 species.

Spergularia rubra, the red sandspurry or red sand-spurrey, is a plant species in the family Caryophyllaceae. It is native to Europe, Asia and North Africa, and it is present on other continents, including North and South America and Australia, as an introduced species and in many areas a common weed. It grows in a wide variety of habitat types. It is an annual or perennial herb producing a slender, glandular stem up to about 25 centimeters (9.8 in) long. It is lined with slightly fleshy linear or threadlike leaves each under 2 centimeters long. The leaves may be tipped with hard points or

Spergularia media (syn. S. maritima) is a species of flowering plant in the family Caryophyllaceae known by the common names media sandspurry and greater sea-spurrey. It is native to Eurasia and the Mediterranean, where it grows in many types of habitat, including disturbed areas, including places with saline substrates, such as salt marshes and beaches. It is known in many other parts of the world as an introduced species and a common roadside weed. In North America it is a "highway halophyte", often springing up at the margins of roads that are heavily salted in the winter.

Nephrolepis cordifolia is a fern native to the global tropics, including northeastern Australia and Asia. It has many common names including fishbone fern, tuberous sword fern, tuber ladder fern, erect sword fern, narrow sword fern and ladder fern, and herringbone fern.

The Loxsomataceae are a family of ferns in the order Cyatheales with two extant genera in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may be treated as the subfamily Loxsomatoideae of a very broadly defined family Cyatheaceae, the system used in Plants of the World Online as of November 2019. It has leaves that can be as long as 5 metres (16 ft) long. Extant species in this family are found in New Zealand, Costa Rica, and South America. Fossil species in this family, dating from as early as the Jurassic, have been found in North America, India

Matoniaceae is one of the three families of ferns in the Gleicheniales order of the Polypodiopsida class. Fossil records reveal that Matoniaceae ferns were abundant during the Mesozoic era (about 250-million to 66-million years ago), during which they lived on every continent, including Antarctica, with eight genera and 26 species, with the oldest known specimens being from the Middle Triassic of Antarctica. Today the family is much less abundant, and also less diverse, with only two extant genera and four species, which are limited to portions of southeastern Asia. The following diagram

Sarcoglottis is a genus of flowering plants from the orchid family, Orchidaceae. It is widespread across much of Latin America from Mexico to Argentina, with one species extending northward into Trinidad and the Windward Islands.

Pyrostegia is a genus of plants in the family Bignoniaceae, native to tropical and subtropical areas of the Americas.

Adiantum raddianum, the Delta maidenhair fern, is one of the most popular ferns to grow indoors. It is native to South America and its common name comes from its shiny, dark leafstalks that resemble human hair. It typically grows about 17–19 in (43–48 cm) tall and up to 22 in (56 cm) wide. In the wild, it is found on forest floors, rock crevices, river banks, coastal cliffs, and basalt banks along trails and streams. The triangular fronds are semi-erect in the beginning then droop gracefully as they age and can be up to 12 inches (30 cm) long by 6 inches (15 cm) wide. The genus name Adiantum

The gelechioid moth genus Stenoptera, established by Duponchel in 1838, is a junior synonym of Esperia. The gall midge genus Stenoptera, invalidly established by Meunier in 1902, has been renamed Neostenoptera. Stenoptera is a genus of flowering plants from the family Orchidaceae, endemic to South America.

Microchilus is a neotropical genus of about 261 species belonging to the orchid family (Orchidaceae). The native range of this genus is tropical & subtropical America. It was first described by Carl Borivoj Presl in 1827, but the genus was not widely recognized until it was separated in 2002 by P. Ormerod from the genus Erythrodes s. str.. It corresponds to its New World species. The two genera were distinguished by the different characters of the column and pollinia. It need dissecting the flowers, to see the differences at generic level with Erythrodes. In 2005, another 32 new species were

Osmundastrum cinnamomeum, commonly known as the cinnamon fern or the buckhorn fern, is a species of royal fern native to the Americas and Asia. It is the sole living representative of the genus Osmundastrum, which was separated from Osmunda after modern phylogenetic studies demonstrated that Osmunda was not monophyletic. In North America it occurs from southern Labrador west to Ontario, and south through the eastern United States to eastern Mexico and the West Indies; in South America it occurs west to Peru and south to Paraguay. In Asia it occurs from southeastern Siberia south through

Metaxya is a neotropical genus of ferns in the order Cyatheales. It is the only genus in the family Metaxyaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the genus may be placed in the subfamily Metaxyoideae of a more broadly defined family Cyatheaceae, the family placement used in Plants of the World Online as of November 2019. The species of the genus are characterized by large fronds that approach 8 ft (2.5 m) in length.

Lactuca viminea, the pliant lettuce, is a Eurasian plant species in the tribe Cichorieae within the family Asteraceae. It is widespread across much of Europe and southwestern Asia from Portugal to Pakistan. Lactuca viminea is a branching subshrub up to 30 cm tall. Leaves near the base are pinnately lobed, but the leaves on the stem are narrow and linear, not lobed, becoming smaller higher up the plant. The uppermost leaves are pressed against the stem and almost scale-like. Flower heads have 4–5 yellow ray flowers, but no disc flowers. Subspecies Lactuca viminea subsp. chondrilliflora

Polystichum munitum, the western swordfern, is an evergreen perennial fern native to western North America, where it is one of the most abundant ferns in forested areas. It occurs along the Pacific coast from southeastern Alaska to southern California, and also inland east to southeastern British Columbia, northern Idaho and western Montana, with disjunctive populations in northern British Columbia, Canada; the Black Hills in South Dakota, United States; and Guadalupe Island off of Baja California, Mexico. Western swordfern is known to have locally naturalized in parts of Great Britain and

Culcita is a genus of ferns, native to the Americas, Macaronesia and Iberian Peninsula. It is the only genus in the family Culcitaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may be treated as the subfamily Culcitoideae of a very broadly defined family Cyatheaceae, the placement used for the genus in Plants of the World Online as of November 2019.

Monochoria was originally a genus of aquatic plants in the water hyacinth family, Pontederiaceae. Currently, it has been reduced to a subgenus of Pontederia, Pontederia subg. Monochoria, represented by ten species (listed below). Its species are native to tropical and subtropical Africa, Asia, and Oceania. They live in the water or in wet soils. They produce leaves on long petioles and some are cultivated for their attractive flowers. Plants from this species have been utilized in the creation of traditional herbal treatments, food, and cosmetics for a very long time.

Cyrtomium is a genus of about 35 species of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Species are native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus Polystichum, with 2016 research suggesting it should be included in a clade sister to Polystichum s.s.

Berberis aetnensis is a shrub in the family Berberidaceae described as a species in 1826. It is native to Southern Italy (Campania, Basilicata, Calabria, Sicily, Sardinia) Croatia, Bosnia and Herzegovina and Montenegro. The species is named for Mount Etna in Sicily.

Rosa nutkana, the Nootka rose, bristly rose, or wild rose is a 0.6–3.0-metre-tall (2–10-foot) perennial shrub in the rose family (Rosaceae). The species name nootka comes from the Nootka Sound of Vancouver Island, where the plant was first described. This plant is native to Western North America. There are 2 varieties: hispida grows in the Intermountain West from east of the Cascades to the Rocky Mountains, and nutkana grows in coastal areas from Alaska to California west to the Cascades. The Jepson Interchange (Flora of California) considers other varieties to be part of the nutkana variety.
