While Erysimum is a genus of flowering plants, the Schisandra is a genus of what?
twining shrub
Erysimum
Erysimum (wallflower) is a genus of flowering plants that includes about 180 species of popular garden plants and many wild forms in the botanical family "Brassicaceae".
 The genus "Cheiranthus" is sometimes included here in whole or in part.
 Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterized by sessile, stellate and/or malpighiaceous trichomes, yellow to orange flowers and multiseeded siliques.
Schisandra
Schisandra (magnolia vine) is a genus of twining shrub that generally climb on other vegetation.
 Some early publications misspell the name as ""Schizandra,"" but ""Schisandra"" is correct.
 Various authors have included the plants in the Illiciaceae
Cyrtandra (plant)
Cyrtandra is a genus of flowering plants containing about 600 species, with more being discovered often, and is thus the largest genus in the family Gesneriaceae.
 These plants are native to Southeast Asia, Australia, and the Pacific Islands, with the centre of diversity in Southeast Asia and the Malesian region.
 The genus is common, but many species within it are very rare, localized, endangered endemic plants.
 The species can be difficult to identify because they are highly polymorphic and because they readily hybridize with each other.
 The plants may be small herbs, vines, shrubs, epiphytes, or trees.
 The genus is characterized in part by having two stamens, and most species have white flowers, with a few red-, orange-, yellow- and pink-flowered species known.
 Almost all species live in rainforest habitats. Austrobaileyales
Austrobaileyales is an order of flowering plants, consisting of about 100 species of woody plants growing as trees, shrubs and lianas.
 Perhaps the most familiar species is "Illicium verum", from which comes the spice star anise.
 The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.
 The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, "Austrobaileya scandens", a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas. Echinacea
Echinacea is a genus, or group of herbaceous flowering plants in the daisy family.
 The "Echinacea" genus has nine species, which are commonly called purple coneflowers.
 They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas.
 They have large, showy heads of composite flowers, blooming from early to late summer.
 The generic name is derived from the Greek word ἐχῖνος ("ekhinos"), meaning "hedgehog," due to the spiny central disk.
 These flowering plants and their parts have different uses.
 Some species are cultivated in gardens for their showy flowers.
 "Echinacea purpurea" is used in folk medicine.
 Two of the species, "E. tennesseensis" and "E. laevigata", are listed in the United States as endangered species. Magnolia virginiana
Magnolia virginiana, most commonly known as sweetbay magnolia, or merely sweetbay (also laurel magnolia, swampbay, swamp magnolia, whitebay, or beaver tree), is a member of the magnolia family, Magnoliaceae.
 It was the first magnolia to be scientifically described under modern rules of botanical nomenclature, and is the type species of the genus "Magnolia"; as "Magnolia" is also the type genus of all flowering plants (magnoliophytes), this species in a sense typifies all flowering plants. Psychotria
Psychotria is a genus of flowering plants in the Rubiaceae family.
 It contains around 1,850 species and is therefore one of the largest genera of flowering plants.
 The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests.
 Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific. Luzula
Luzula is a genus of flowering plants the family Juncaceae, the rushes.
 The genus has a cosmopolitan distribution, with species occurring throughout the world, especially in temperate regions, the Arctic, and higher elevation areas in the tropics.
 Plants of the genus are known commonly as wood-rush, wood rush, or woodrush.
 Possible origins of the genus name include the Italian "lucciola" ("to shine, sparkle") or the Latin "luzulae" or "luxulae", from "lux" ("light"), inspired by the way the plants sparkle when wet with dew.
 Another etymology sometimes given is that it does derive from lucciola but that this meant a midsummerfield, or from the Latin luculus, meaning a small place; the same source also states that this name was applied by Luigi Anguillara (an Italian botanist) in 1561. Wallflower (disambiguation)
Wallflower or "Erysimum" is a genus of flowering plants. Zeltnera
Zeltnera is a genus of flowering plants in the gentian family.
 It was erected in 2004 when the genus "Centaurium" (the centauries) was split.
 Genetic analysis revealed that "Centaurium" was polyphyletic, made up of plants that could be grouped into four clades. Each became a genus.
 "Centaurium" remained, but it is now limited to the Eurasian species.
 The Mexican species now belong to genus "Gyrandra", and the Mediterranean and Australian plants are in genus "Schenkia".
 The new name "Zeltnera" was given to this genus, which contains most of the North American centauries.
 There are about 25 species.
