Prosopis is a genus of flowering plants in the family Fabaceae. It contains around 45 species of spiny trees and shrubs found in subtropical and tropical regions of the Americas, Africa, Western Asia, and South Asia. They often thrive in arid soil and are resistant to drought, on occasion developing extremely deep root systems. Their wood is usually hard, dense and durable. Their fruits are pods and may contain large amounts of sugar. The generic name means "burdock" in late Latin and originated in the Greek language. [4]
Genomic research published in 2022 concludes that species grouped under the genus Prosopis actually represent multiple genera including Anonychium , Neltuma , Prosopis, and Strombocarpa . [5]
Prosopis species have been found to contain 5-hydroxytryptamine, apigenin, isorhamnetin-3-diglucoside, l-arabinose, quercetin, tannin, and tryptamine. [6]
Prosopis alba | Beta-phenethylamine and tryptamine [7] |
Prosopis alpataco | "Aerial parts" contain tryptamine, phenethylamine derivatives. [8] |
Prosopis argentina | "Aerial parts" contain tryptamine, phenethylamine derivatives. [8] |
Prosopis chilensis | "Aerial parts" contain beta-phenethylamine and derivatives plus tryptamine [8] [9] |
Prosopis argentina | Exudate contains tryptamine, phenethylamine derivatives. [8] |
Prosopis glandulosa | Alkaloids in bark and roots, [6] tyramine and N-methyltyramine (a stimulant) in leaves [10] |
Prosopis juliflora | 5-HTP (plant) and tryptamine (plant). [11] |
Prosopis nigra | Harman, eleagnine, and N-acetyltryptamine [12] |
Prosopis pugionata | "Aerial parts" contain tryptamine, phenethylamine derivatives. [8] |
Prosopis tamarugo | Phenethylamine [9] |
The tannins present in Prosopis species are of the pyrogallotannin and pyrocatecollic types. [13] The tannins are mainly found in the bark and wood, while their concentration in the pods is low. [14]
Some species, such as P. africana or P. velutina , produce a gum (mesquite gum). [15]
The species Prosopis pallida was introduced to Hawaii in 1828 and now dominates many of the drier coastal parts of the islands, where it is called the kiawe tree and is a prime source of monofloral honey production. [16]
In Australia, invasive Prosopis species are causing severe economic and environmental damage. With their thorns and many low branches, Prosopis shrubs form impenetrable thickets which prevent cattle from accessing watering holes, etc. They also take over pastoral grasslands and suck up scarce water. Prosopis species cause land erosion due to loss of grassland that are habitats for native plants and animals. Prosopis thickets also provide shelter for feral animals such as pigs and cats. [17]

Eradicating Prosopis is difficult because the plant's bud regeneration zone can extend down to 6 in (150 mm) below ground level; [18] [19] the tree can regenerate from a piece of root left in the soil. [18] Some herbicides are not effective or only partially effective against mesquite. Spray techniques for removal, while effective against short-term regrowth, are expensive, costing more than $70/acre ($170/hectare) in the USA. Removing large trees requires tracked equipment; costs can approach $2,000 per acre. In Australia, several techniques are used to remove Prosopis. [17]
Mesquite is a common name for some plants in the genus Prosopis and Neltuma, both of which contain over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. The trees bloom from spring to summer. They often produce fruits known as "pods". Prosopis spp. are able to grow up to 8 metres (26 ft) tall, depending on site and climate. They are deciduous and depending on location and rainfall have either deep or shallow roots. Prosopis is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite.
Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It was named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides.
Neltuma juliflora , formerly Prosopis juliflora, is a shrub or small tree in the family Fabaceae, a kind of mesquite. It is native to Mexico, South America and the Caribbean. It has become established as an invasive weed in Africa, Asia, Australia and elsewhere. It is a contributing factor to continuing transmission of malaria, especially during dry periods when sugar sources from native plants are largely unavailable to mosquitoes.
Calliandra is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas.
Calandrinia is a genus of flowering plants known as purslanes and redmaids. It includes 37 species of annual and perennial herbs which bear colorful flowers in shades of red to purple and white. Species of this genus are native to the Americas, including western and southern South America, Central America, and western North America. Some species have been introduced to parts of Australia, New Zealand, southern Africa, Asia, and Europe. Over 60 species native to Australia and New Guinea that were formerly included in Calandrinia are now placed in a separate genus, Rumicastrum or Parakeelya. A single eastern Australian species named in 2022, Calandrinia petrophila, is still included in Calandrinia, but will be placed into the Australian genus when the name of the new genus is finally settled.
Strombocarpa pubescens, commonly known as screwbean mesquite, is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States and northern Mexico.
Senna, the sennas, is a large genus of flowering plants in the legume family. 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.
Prosopis pallida is a species of mesquite tree. It has the common names kiawe, huarango and American carob, as well as "bayahonda", "algarrobo pálido", and "algarrobo blanco". It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast. While threatened in its native habitat, it is considered an invasive species in many other places.
Colletia is a genus of flowering plants in the family Rhamnaceae, with five species of spiny shrubs. All species of this genus are native to southern South America. They are non-legume nitrogen fixers.
Centrosema, the butterfly peas, is a genus of American vines in the legume family (Fabaceae). It includes 44 species, which range through the tropical and warm-temperate Americas from the southern United States to northern Argentina. Species include:
Prosopis tamarugo, commonly known as the tamarugo, is a species of flowering tree in the pea family, Fabaceae, subfamilia Mimosoideae. It is only found in northern Chile, particularly in the Pampa del Tamarugal, some 70 km (43 mi) east of the city of Iquique. This bushy tree apparently grows without the benefit of rainfall, and it is thought to obtain some water from dew. Studies indicate it is a Phreatophyte; having deep roots that tap into ground water supplies. It also participates in hydraulic redistribution moving water from deeper levels to the upper and also reversing the process in times of severe drought.
Senegalia is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. The genus was considered polyphyletic and required further division, with the genera Parasenegalia and Pseudosenegalia accepted soon after.
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.
Adesmia is a genus of flowering plants in the legume family, Fabaceae. It was recently assigned to the informal monophyletic Adesmia clade within the Dalbergieae.
Galactia is a genus of plants in the legume family (Fabaceae). It belongs to the subfamily Faboideae and tribe Diocleae They do not have an unambiguous common name, being commonly called milk peas, beach peas or wild peas. They are perennial herbs or subshrubs with prostrate, climbing, or erect forms.
Neltuma is a genus of flowering plants in the pea family (Fabaceae). It includes 43 species native to the Americas. The species range from the southwestern and central United States through Mexico, Central America, the Caribbean, and South America to southern Argentina and Uuguay. Some species, along with members of the closely related Prosopis, are known as mesquites.
