Acacia s.l., known commonly as mimosa, acacia, thorntree or wattle, is a polyphyletic genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae. It was described by the Swedish botanist Carl Linnaeus in 1773 based on the African species Acacia nilotica. Many non-Australian species tend to be thorny, whereas the majority of Australian acacias are not. All species are pod-bearing, with sap and leaves often bearing large amounts of tannins and condensed tannins that historically found use as pharmaceuticals and preservatives.
Vachellia farnesiana, also known as Acacia farnesiana, and previously Mimosa farnesiana, commonly known as sweet acacia, huisache, or needle bush, is a species of shrub or small tree in the legume family, Fabaceae. Its flowers are used in the perfume industry.
Acacia, commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is Neo-Latin, borrowed from the Greek ἀκακία, a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of Vachellia nilotica, the original type of the genus. In his Pinax (1623), Gaspard Bauhin mentioned the Greek ἀκακία from Dioscorides as the origin of the Latin name.
Vachellia tortilis, widely known as Acacia tortilis but now attributed to the genus Vachellia, is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa, but also occurring in the Middle East.
Vachellia erioloba, the camel thorn, also known as the giraffe thorn, mokala tree, or Kameeldoring in Afrikaans, still more commonly known as Acacia erioloba, is a tree of southern Africa in the family Fabaceae. Its preferred habitat is the deep dry sandy soils in parts of South Africa, Botswana, the western areas of Zimbabwe and Namibia. It is also native to Angola, south-west Mozambique, Zambia and Eswatini. The tree was first described by Ernst Heinrich Friedrich Meyer and Johann Franz Drège in 1836. The camel thorn is a protected tree in South Africa.
Vachellia caven is an ornamental tree in the family Fabaceae. Vachellia caven is native to Argentina, Bolivia, Chile, Paraguay, Uruguay and Rio Grande do Sul in Brazil. It grows four to five metres tall and bears very stiff and sharp white thorns up to 2 cm in length. It blooms in spring, with bright yellow flower clusters 1–2 cm (0.39–0.79 in) in diameter.
Vachellia nilotica, more commonly known as Acacia nilotica, and by the vernacular names of gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia, is a flowering tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a 'weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States.
Vachellia nilotica subsp. adstringens is a perennial tree. It is not listed as being threatened. Some common names for it are cassie, piquants blancs and piquant lulu. Its geographic distribution includes Africa, Asia, the Indian Ocean area and the Middle East.
Vachellia karroo, (synonym Acacia karroo} commonly known as the sweet thorn, common acacia, Karoo thorn, Cape gum or cockspur thorn, is a species of Vachellia, in the Mimosa sub-family of the Fabaceae or pea family, which is native to southern Africa from southern Angola east to Mozambique, and south to South Africa.
Vachellia seyal, the red acacia, known also as the shittah tree, is a thorny, 6– to 10-m-high tree with a pale greenish or reddish bark. At the base of the 3–10 cm (1.2–3.9 in) feathery leaves, two straight, light grey thorns grow to 7–20 cm (2.8–7.9 in) long. The blossoms are displayed in round, bright yellow clusters about 1.5 cm (0.59 in) diameter.
Vachellia sieberiana, until recently known as Acacia sieberiana and commonly known as the paperbark thorn or paperbark acacia, is a tree native to southern Africa and introduced into Pakistan. It is used in many areas for various purposes. The tree varies from 3 to 25 m in height, with a trunk diameter of 0.6 to 1.8 m. It is not listed as being a threatened species.
Vachellia nilotica subsp. indica is a perennial tree native to Bangladesh, India, Myanmar, Nepal and Pakistan. It is also cultivated in Angola, Egypt, Ethiopia, and Tanzania. Common names for it include babul, kikar and prickly acacia.
Vachellia nilotica subsp. kraussiana is a perennial tree native to Africa. All examples in southern Africa can be assigned to this race.
Vachellia nilotica subsp. subalata is a perennial tree native to Africa, India and Pakistan. Its uses include forage and wood. A common name for it is kauria babul.
Vachellia nilotica subsp. tomentosa is a perennial tree native to Africa, Asia and India.
Vachellia drepanolobium, more commonly known as Acacia drepanolobium or whistling thorn, is a swollen-thorn acacia native to East Africa. The whistling thorn grows up to 6 meters tall. It produces a pair of straight spines at each node, some of which have large bulbous bases. These swollen spines are naturally hollow and occupied by any one of several symbiotic ant species. The common name of the plant is derived from the observation that when wind blows over bulbous spines in which ants have made entry and exit holes, they produce a whistling noise.
Vachellia is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus Acacia until 2009. Vachellia can be distinguished from other acacias by its capitate inflorescences and spinescent stipules. Before discovery of the New World, Europeans in the Mediterranean region were familiar with several species of Vachellia, which they knew as sources of medicine, and had names for them that they inherited from the Greeks and Romans.
Vachellia reficiens, commonly known as red-bark acacia, red thorn, false umbrella tree, or false umbrella thorn, is a deciduous tree or shrub of the pea family (Fabaceae) native to southern Africa, often growing in an upside-down cone shape and with a relatively flat crown.
Vachellia flava, synonym Acacia ehrenbergiana, is a species of drought-resistant bush or small tree, commonly known as salam in Arabic. It is found in the Sahara, the northern Sahel, parts of East Africa, the Arabian Peninsula and Iran.
