Honeysuckles ("Lonicera", ; syn.
 "Caprifolium" Mill.
) are arching shrubs or twining bines in the family Caprifoliaceae, native to the Northern Hemisphere.
 Approximately 180 species of honeysuckle have been identified.
 About 100 of these species can be found in China and approximately 20 native species have been identified in Europe, 20 in India, and 20 in North America.
 Widely known species include "Lonicera periclymenum" (honeysuckle or woodbine), "Lonicera japonica" (Japanese honeysuckle, white honeysuckle, or Chinese honeysuckle) and "Lonicera sempervirens" (coral honeysuckle, trumpet honeysuckle, or woodbine honeysuckle).
 Hummingbirds are attracted to the flowers on some of these plants, especially "L. sempervirens" and "L. ciliosa" (orange honeysuckle).
 Honeysuckle derives its name from the edible sweet nectar obtainable from its tubular flowers.
 The name "Lonicera" stems from Adam Lonicer, a Renaissance botanist.
Lonicera caprifolium, the Italian woodbine, perfoliate honeysuckle, goat-leaf honeysuckle, Italian honeysuckle, or perfoliate woodbine, is a species of perennial flowering plants in the genus "Lonicera" of the Caprifoliaceae family.
 It is native to parts of Europe, and naturalised in South East Britain and northeastern North America.
 It can readily be distinguished from Europe's most common species, "Lonicera periclymenum", by its topmost leaves which are perfoliate as the Latin name suggests (that is, the stem appears to grow through the centre of the leaf).
 It is a vigorous, deciduous climber growing up to 8 metres.
 It bears masses of very fragrant, cream-coloured flowers, tinged with pink, appearing in midsummer.
Calicotome is a genus of flowering plants in the legume family, Fabaceae.
 It belongs to the sub family Faboideae.
 It may be synonymous with "Cytisus".
 All species of the genus are thorny shrubs.
 The ancient Greeks believed that tyrants in Hades were punished by being beaten with the thorny calycotomes.
Genista is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia.
 They include species commonly called broom, though the term may also refer to other genera, including "Cytisus" and "Chamaecytisus".
 Brooms in other genera are sometimes considered synonymous with "Genista": "Echinospartum", "Retama", "Spartium", "Stauracanthus", and "Ulex".
Peltophorum is a genus of 5–15 species of flowering plants in the family Fabaceae, subfamily Caesalpinioideae.
 The genus is native to certain tropical regions across the world.
 The species are medium-sized to large trees growing up to 15–25 m (rarely 50 m) tall.
Senna (from Arabic "sanā"), the sennas, is a large genus of flowering plants in the legume family Fabaceae, and the subfamily Caesalpinioideae.
 This diverse genus is native throughout the tropics, with a small number of species in temperate regions.
 The number of species is estimated to be from about 260 to 350.
 The type species for the genus is "Senna alexandrina".
 About 50 species of "Senna" are known in cultivation.
Ulex (commonly known as gorse, furze or whin) is a genus of flowering plants in the family Fabaceae.
 The genus comprises about 20 species of thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae.
 The species are native to parts of western Europe and northwest Africa, with the majority of species in Iberia.
Cytisus is a genus of about 50 species of flowering plants in the family Fabaceae, native to open sites (typically scrub and heathland) in Europe, western Asia and North Africa.
 It belongs to the subfamily Faboideae, and is one of several genera in the tribe Genisteae which are commonly called brooms.
 They are shrubs producing masses of brightly coloured, pea-like flowers, often highly fragrant.
 Members of the segregate genera, "Calicotome" and "Lembotropis" are sometimes included in "Cytisus".
Flemingia is a genus of flowering plants in the legume family Fabaceae.
 It is native to Asia and the species are distributed in Bhutan, Burma, China, India; Indonesia, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.
 The genus was founded in 1812.
 The number of known species is ambiguous due to taxonomic problems; and is usually enumerated as more than 30.
 Burma and China have the highest record of "Flemingia" species with 16 each, followed by India (with 15 species), Thailand (11 species), Laos (10 species), Vietnam (8 species), Bhutan (1 species) and Nepal (5 species).
Canavalia is a genus of flowering plants in the legume family (Fabaceae) and comprises approximately 48 to 50 species of tropical vines. Members of the genus are commonly known as jack-beans.
 The species of "Canavalia" endemic to the Hawaiian Islands were named ʻ āwikiwiki by the Native Hawaiians.
 The name translates to "the very quick one" and comes from the Hawaiian word for "fast" that has also been appropriated into the name "Wikipedia".
 The genus name is derived from the Malabar word for the species, "kavavali", which means "forest climber."
