Orbexilum, commonly called leather-root, [2] is a genus of flowering plants in the legume family (Fabaceae). They are native to North America, where they are found in the United States and Mexico, south to Chiapas. [3]
This genus can be distinguished from other genera in the Psoraleeae by its "thick glabrous pod walls that are distinctively rugose and by [a] calyx that is scarcely accrescent." [4]
The genus was described by Constantine Samuel Rafinesque in 1832, with the type species O. latifolia, moved from Psoralea . [5] (O. latifolia is now considered a synonym of O. onobrychis. [6] ) Rafinesque differentiated Orbexilum from Psoralea largely on the basis of features of the calyx. [7]
Orbexilum comprises the following species: [1] [4]
Penstemon, the beardtongues, is a large genus of roughly 280 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. As well as being the scientific name, penstemon is also widely used as a common name for all Penstemon species alongside beardtongues.
Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.
Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion.
Amorpha is a genus of plants in the pea family, Fabaceae. All the species are native to North America, from southern Canada, most of the United States (US), and northern Mexico. They are commonly known as false indigo. The name Amorpha means "deformed" or "without form" in Greek and was given because flowers of this genus only have one petal, unlike the usual "pea-shaped" flowers of the Faboideae subfamily. Amorpha is missing the wing and keel petals.
Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. As of October 2022, the taxonomy of Tiarella in eastern North America is in flux.
Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus Senecio, but were moved to a different genus based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.
Baptisia is a genus in the legume family, Fabaceae. They are flowering herbaceous perennial plants with pea-like flowers, followed by pods, which are sometimes inflated. They are native to woodland and grassland in eastern and southern North America. The species most commonly found in cultivation is B. australis.
Heterotheca is a genus of North American plants in the family Asteraceae.
Dalea is a genus of flowering plants in the legume family, Fabaceae. Members of the genus are commonly known as prairie clover or indigo bush. Its name honors English apothecary Samuel Dale (1659–1739). They are native to the Western hemisphere, where they are distributed from Canada to Argentina. Nearly half of the known species are endemic to Mexico. Two species of Dalea have been considered for rangeland restoration.
Tiarella trifoliata, the three-leaf foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name trifoliata means "having three leaflets", a characteristic of two of the three recognized varieties. Also known as the laceflower or sugar-scoop, the species is found in shaded, moist woods in western North America.
Hylodesmum is a genus of flowering plants in the family Fabaceae, sometimes called ticktrefoils or tick-trefoils. It is sometimes treated as part of Desmodium. It includes 16 species native to eastern North America, sub-Saharan Africa, Yemen, south, southeast, and eastern Asia, Malesia, and New Guinea.
The tribe Psoraleeae is one of the subdivisions of the plant family Fabaceae. Recent phylogenetics has this tribe nested within tribe Phaseoleae.
Suaeda nigra, often still known by the former name Suaeda moquinii, is a species of flowering plant in the amaranth family, known by the vernacular names bush seepweed or Mojave sea-blite.
Trillium angustipetalum, with the common name is narrowpetal wakerobin, is a species of Trillium, plants which may be included within the Liliaceae or the newer family Melanthiaceae.
Arisaema quinatum is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of closely related taxa in eastern North America. The specific name quinatum means "divided into five lobes", a reference to its characteristic leaves. It is commonly known as the southern Jack-in-the-pulpit but some refer to it as Preacher John.
Symphyotrichum oolentangiense, commonly known as skyblue aster and azure aster, is a species of flowering plant in the family Asteraceae native to eastern North America.
Orbexilum onobrychis, commonly called French-grass or lanceleaf scurfpea, is a species of flowering plant in the legume family (Fabaceae). It is native to the eastern United States where its range is concentrated in the Midwest and Upper South. Its natural habitat is primarily prairies and riverbanks, typically in mesic or wet areas. It is an uncommon species, and can be found in high-quality prairie remnants as well as more disturbed areas.
Astragalus plattensis, the Platte River milkvetch, is a species of flowering plant in the legume family, Fabaceae, native to North America. It was named in 1838. Its range includes the Great Plains of the United States, from southern Montana and North Dakota south to central Texas.
Taraxia is a small genus of flowering plants in the family Onagraceae, native to western Canada and the western and west-central United States. Nuclear DNA evidence shows that it is sister to a clade containing all genera in the tribe Onagreae except for Oenothera, Eulobus, and Chylismia.
