The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek [poly meaning 'many' and gony meaning 'knee' or 'joint']. Alternatively, it may have a different origin, meaning 'many seeds'.
Primula sect. Dodecatheon is a section of herbaceous flowering plants in the family Primulaceae. Primula species in this section were formerly placed in a separate genus, Dodecatheon. The species have basal clumps of leaves and nodding flowers that are produced at the top of tall stems rising from where the leaves join the crown. The genus is largely confined to North America and part of northeastern Siberia. Common names include shooting star, American cowslip, mosquito bills, mad violets, and sailor caps. A few species are grown in gardens for their showy and unique flower display.
Paul Arnold Fryxell was an American botanist known for his work on flowering plants, especially those within the Malvaceae.
Rupert Charles Barneby was a British-born self-taught botanist whose primary specialty was the Fabaceae (Leguminosae), the pea family, but he also worked on Menispermaceae and numerous other groups. He was employed by the New York Botanical Garden from the 1950s until shortly before his death.
Oxytheca is a genus of plants in the family Polygonaceae with seven species found in dry and temperate parts of the Americas. The taxonomy of this genus is in flux, with some species often listed under tentative new names.
John Thomas Howell was an American botanist and taxonomist. He became an expert of Eriogonum (buckwheat) species, which are widely represented in the native California flora.
Primula latiloba, synonyms Dodecatheon dentatum and Dodecatheon latilobum, is a species of flowering plant in the family Primulaceae, known by the common names white shooting star and toothed American cowslip.
Dicranopteris (forkedfern) is a genus of tropical ferns of the family Gleicheniaceae. There are about 20 described species.
Polygonum delopyrum, the fringed jointweed or hairy jointweed, is a plant species endemic to Florida. It is found in pinelands and sandy pine barrens at elevations less than 50 m, in central and southern parts of the state.
Patricia May Holmgren is an American botanist. Holmgren's main botanical interests are the flora of the U.S. intermountain west and the genera Tiarella and Thlaspi. Holmgren was the director of the herbarium at the New York Botanical Garden from 1981–2000, and editor of Index Herbariorum from 1974–2008.
Reynoutria is a genus of flowering plants in the Polygonaceae, also known as the knotweed or buckwheat family. The genus is native to eastern China, Eastern Asia and the Russian Far East, although species have been introduced to Europe and North America. Members of the genus, including R. japonica and its hybrid with R. sachalinensis, are highly invasive plants.
Hybanthopsis is a genus of flowering plants in the violet family Violaceae, with a single accepted species, found in north-east Brazil.
Aquilegia barnebyi, commonly known as the oil shale columbine or Barneby's columbine, is a perennial species of flowering plant in the buttercup family, with a native range comprising northeastern Utah and northwestern Colorado in the United States. It is named after Rupert Charles Barneby, who, with Harry Dwight Dillon Ripley, first discovered it in Colorado.
Stanmarkia is a genus of flowering plants belonging to the family Melastomataceae.
Primula standleyana, synonym Dodecatheon ellisiae, is a species of flowering plant in the family Primulaceae, native to Arizona, New Mexico and Northeast Mexico. It was first described by Paul Carpenter Standley in 1913 as Dodecatheon ellisiae. When the genus Dodecatheon was reduced to Primula sect. Dodecatheon following molecular phylogenetic studies, the species could not be transferred to Primula as Primula ellisiae, as that name had already been used for a different species. Accordingly, the replacement name Primula standleyana was provided.
Primula utahensis, synonym Dodecatheon utahense, is a species of flowering plant in the family Primulaceae, native to Utah. It was first described by Noel Holmgren in 1994 as Dodecatheon dentatum var. utahense. In 2006, it was raised to a separate species as Dodecatheon utahense. When Dodecatheon was sunk into Primula in 2007, it was transferred to that genus as Primula utahensis.
Aglaomorpha willdenowii is a species of subtropical fern native to the islands of Comoros, Madagascar, and Mauritius. Drynarioid ferns are largely native to Asia and Oceania, but A. willdenowii is the only species of fern in the genus native to Madagascar. Like other Aglaomorpha, its caudex is covered in dry, scale-like sterile fronds and fine hairs, while the larger green fronds are the fertile ones bearing spores.
Abuta colombiana is a species of flowering plant in the Menispermaceae family. It is part of the genus Abuta, which consists of about 32 species native to tropical Central and South America. Abuta colombiana is native to Colombia and northern Brazil, and has been observed in Ecuador and Panama. It was first published in Brittonia in 1938, described from two specimens collected from the Chocó Department in north Colombia. It is closely related to Abuta imene but can be distinguished by the flower stamens.
Begonia longifolia is a species of flowering plant in the family Begoniaceae. It is native to the eastern Himalayas, southern China, Hainan, Taiwan, mainland Southeast Asia, and some of the islands of Indonesia. An erect perennial herb reaching 1.5 m (5 ft), it is typically found in shady, moist forests at elevations from 200 to 2,200 m. It is the most widespread species of Begonia in Asia, and probably in the world.
Monstera praetermissa is a species of plant in the genus Monstera native to Brazil. It grows in wet tropical forests from 50–900 metres (160–2,950 ft) in elevation. It is most similar to Monstera obliqua and Monstera xanthospatha, but differs from these in habitat (Brazil) and in its inflorescence. Like many in its genus, the species transitions from a juvenile leaf shape, typically at about 15 centimetres (5.9 in) in growth, to an adult leaf that has up to five perforations per side. Its species name means "overlooked" in Latin, due to its only recent scientific description in 2004 and lack of attention from collectors.
