Inga is a genus of small tropical, tough-leaved, nitrogen-fixing trees [2] and shrubs, subfamily Mimosoideae. Inga's leaves are pinnate, and flowers are generally white. Many of the hundreds of species are used ornamentally.
Several related plants have been placed into this genus at one time, for example Yopo (Cohoba, Mopo, Nopo or Parica – Anadenanthera peregrina – as Inga niopo). [3]
The seeds are covered with sweet white powder. The pulp covering the seeds is lightly fibrous and sweet, and rich in minerals; it is edible in the raw state. The tree's name originates from the Tupi word in-gá meaning "soaked", due to the fruit powder consistency. [4] The tree usually blooms twice a year.
Within the Inga genus there are around 300 species, most of them native and growing in the Amazon forest region although some species are also found in Mexico, Greater and Lesser Antilles and other countries in South America, being an exclusively neotropical genus. The trees are usually found by river and lake edges because their seeds are carried there by floods.
All Inga species produce their seeds in "bean-like" pods and some can reach up to 1 m long, in general the pods are 10–30 cm long.
Trees can reach up to 15 metres and they are widely used for producing shade over coffee plants. The plant benefits from well drained soil. The flowers are white with some green and the tree can produce fruits almost all year long.
Inga species, most notably Inga edulis (commonly known as "ice-cream-bean" or, in Spanish, "guama", "guaba", "guaba de bejuco" or "paterna" depending on the country or region) often have edible pulp. The name derives from the fact that those of I. edulis resembles vanilla ice cream in flavour.
In Ecuador, Inga edulis is known as "guaba de bejuco" and, the other popular species there, Inga spectabilis , as "guaba de machete". [5]
Alley cropping techniques using species of Inga have been developed to restore soil fertility, and thereby stem the tide of continual slashing and burning of the rainforest. [6] [7] Species which have proven effective for alley cropping include Inga edulis and Inga oerstediana . Much of the research was done by Mike Hands at Cambridge University over a 20-year period. [2] Inga species are also commonly used as shade trees for coffee, cocoa, and tea. [8]
It is often used as lumber in construction and furniture making. [9]
The cocoa bean or simply cocoa, also called cacao, is the dried and fully fermented seed of Theobroma cacao, from which cocoa solids and cocoa butter can be extracted. Cocoa beans native to the Ecuadorian Amazon rainforest are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink.
Pachyrhizus is a genus of flowering plants in the legume family, Fabaceae. It includes five or species of herbs and subshrubs native to the tropical and subtropical Americas, ranging from northern Mexico to northwestern Argentina. Typical habitat is seasonally-dry tropical forest and thicket, often at forest margins, in scrub vegetation, and in open grassy areas. Plants in the genus grow from large, often edible taproots.
Tamarind is a leguminous tree bearing edible fruit that is indigenous to tropical Africa and naturalized in Asia. The genus Tamarindus is monotypic, meaning that it contains only this species. It belongs to the family Fabaceae.
The carob is a flowering evergreen tree or shrub in the Caesalpinioideae sub-family of the legume family, Fabaceae. It is widely cultivated for its edible fruit pods, and as an ornamental tree in gardens and landscapes. The carob tree is native to the Mediterranean region and the Middle East. Portugal is the largest producer of carob, followed by Italy and Morocco.
Erythrina is a genus of plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, with the larger species growing up to 30 m (98 ft) in height. The generic name is derived from the Greek word ερυθρóς erythros, meaning "red", referring to the flower color of certain species.
Pachyrhizus erosus, commonly known as jícama or Mexican turnip, is a native Mexican vine, although the name jícama most commonly refers to the plant's edible tuberous root. It is in the pea family (Fabaceae). Pachyrhizus tuberosus and Pachyrhizus ahipa are the other two cultivated species in the genus. The naming of this group of edible plants can sometimes be confusing, with much overlap of similar or the same common names.
The palm tree Phytelephas aequatorialis, commonly known as Ecuadorian ivory palm, is the main source of Ecuadorean vegetable ivory or tagua, a botanical alternative to ivory. It is found in the tropical rainforests of the western Andean slopes of Ecuador. It has a woody trunk which can grow to 20 m in height and very long pinnate leaves.
Inga feuilleei, commonly known as pacay or ice-cream bean tree, is a tree in the family Fabaceae native to Andean valleys of northwestern South America. Pacay trees, as is the case with other trees in genus Inga, produce pods that contain an edible white pulp and have nitrogen-fixing roots.
Muntingia is a genus of plants in the family Muntingiaceae, comprising only one species, Muntingia calabura, and was named in honour of Abraham Munting. It is native to the Neotropics, from Mexico south to Bolivia and Argentina, with edible fruit, and has been widely introduced in other tropical areas.
Pithecellobium dulce, commonly known as Manila tamarind, Madras thorn, monkeypod tree or camachile, is a species of flowering plant in the pea family, Fabaceae, that is native to the Pacific Coast and adjacent highlands of Mexico, Central America, and northern South America. It is also sometimes known as monkeypod, but that name is also used for several other plants, including Samanea saman. It is an introduced species and extensively naturalized in the Caribbean and Florida, as well as the Philippines and Guam via the Manila galleons. It has also been introduced to Thailand and South Asia, It is considered an invasive species in Hawaii.
Erythrina fusca is a species of flowering tree in the legume family, Fabaceae. It is known by many common names, including purple coraltree, gallito, bois immortelle, bucayo, and the more ambiguous "bucare" and "coral bean". E. fusca has the widest distribution of any Erythrina species; it is the only one found in both the New and Old World. It grows on coasts and along rivers in tropical Asia, Oceania, the Mascarene Islands, Madagascar, Africa, and the Neotropics.
Inga edulis, known as ice-cream bean, ice-cream-bean, joaquiniquil, cuaniquilguama or guaba, is a fruit native to South America. It is in the mimosoid tribe of the legume family Fabaceae. It is widely grown, especially by Indigenous Amazonians, for shade, food, timber, medicine, and production of the alcoholic beverage cachiri. It is popular in Peru, Ecuador, Pernambuco-Brazil, Venezuela and Colombia. The taxonomic name Inga is derived from its name with the Tupí people of South America (ingá) while the species name edulis is Latin for "edible". The common name "ice-cream bean" alludes to the sweet flavor and smooth texture of the pulp.
Brownea grandiceps is a species of tree in the family Fabaceae. Its common names include the rose of Venezuela and the scarlet flame bean. It originated in South America but is now widely grown as a decorative tree in tropical gardens.
Parkia biglobosa, known in English as the African locust bean, is a perennial deciduous tree in the family Fabaceae. It is found in a wide range of environments in Africa and is primarily grown for its pods that contain both a sweet pulp and valuable seeds. Where the tree is grown, the crushing and fermenting of these seeds constitutes an important economic activity. Various parts of the locust bean tree are used for medicinal and food purposes. As a standing tree, locust bean may have a positive effect on the yield of other nearby crops.
Erythrina edulis (basul) is a nitrogen fixing tree that is native to the Andean region from western Venezuela to southern Bolivia. Nowadays it is known in Venezuela as "frijol mompás", in Bolivia, Peru and Northwest Argentina as "psonay", "pajuro", "sachaporoto del basul" or "poroto del sacha", in Colombia as "chachafruto", "balú", "baluy" or "sachaporoto" and in Ecuador as "guato". Although it is widely known, it is not commonly cultivated. Future research is needed, especially in agroforestry. Basul is a legume and so it produces protein-rich beans covered in pods which can be used for human or animal nutrition. The leaves and branches can be used as fodder. Besides the agricultural aspects, Erythrina edulis can also be used as a fence plant.
Inga alley cropping is the planting agricultural crops between rows of Inga trees. It has been promoted by Mike Hands.
The environmental impact of cocoa production includes deforestation, soil contamination, and herbicide resistance. The majority of cocoa farms are now located in Côte d'Ivoire and Ghana.
Theobroma bicolor, known commonly as the mocambo tree, jaguar tree, balamte, or pataxte, among various other common names, is a tree in the genus Theobroma, which also contains the better-known Theobroma cacao. It is found in Central and South America, including stretches of the Amazon rainforest in Brazil, Colombia, Ecuador, and Peru.
Inga adenophylla is a species of tree in the family Fabaceae. It is native to South America, particularly the countries of Bolivia and Peru.
Inga oerstediana is a species of tree in the family Fabaceae. It was described by English botanist George Bentham. It can be found in Mexico, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia, Brazil and Trinidad and Tobago.
