Guiera senegalensis | |
Guiera is a flowering plant genus in the family Combretaceae. Guiera senegalensis is the only known species in the genus, found in Tropical Africa in dry areas from Senegal to Sudan (requiring much sunlight and light dry soil). [1] The plant produces the tannin 3,4,5-Tri-O-galloylquinic acid and several alkaloids of the harmane family. [2]
The plant as a whole is often decorative, however the leaves are known as a medicinal 'cure-all' in Africa: It is known for being hypotensive, antidiarrhetic, anti-inflammatory, and helpful for coughs.
Its bark yields a marketable gum; its branches are used for baskets, framework, and fences; its roots for toothpicks; and its smoke repels flies. [1]
Guiera is a pioneer species, spread via animal dispersal and grows well in impoverished soil.
It is an indicator species of overgrazed land. [1]
Guiera naturally "pumps" water to the surface in a process called hydraulic lift or hydraulic redistribution (HR): When grown as a companion plant with millet and other thirsty crops, excess water drawn up by Guiera senegalensis’ deep roots during the night is excreted and becomes available to the surrounding crop, dramatically increasing the yield in the case of millet. [3] [4]
Millets are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa.
Eleusine coracana, or finger millet, also known as kelvaragu in India, kodo in Nepal, and kurakkan in Sri Lanka, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.
Crotalaria is a genus of flowering plants in the family Fabaceae commonly known as rattlepods. The genus includes over 700 species of herbaceous plants and shrubs. Africa is the continent with the majority of Crotalaria species, which are mainly found in damp grassland, especially in floodplains, depressions and along edges of swamps and rivers, but also in deciduous bush land, roadsides and fields. Some species of Crotalaria are grown as ornamentals. The common name rattlepod or rattlebox is derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken. The name derives from the Ancient Greek κρόταλον, meaning "castanet", and is the same root as the name for the rattlesnakes (Crotalus).
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in ca 10 genera. The family includes the leadwood tree, Combretum imberbe. Three genera, Conocarpus, Laguncularia, and Lumnitzera, grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from Terminalia ivorensis. The commonly cultivated Quisqualis indica is now placed in the genus Combretum. Many plants in the former Quisqualis genus contain the excitotoxin quisqualic acid, a potent AMPA agonist.
Pearl millet is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. 2023 is the International Year of Millets, declared by the United Nations General Assembly in 2021.
The winged bean, also known as cigarillas, goa bean, four-angled bean, four-cornered bean, manila bean, princess bean, asparagus pea, dragon bean, is a tropical herbaceous legume plant.
Cenchrus purpureus, synonym Pennisetum purpureum, also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to the African grasslands. It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.
Ricinodendron is a plant genus in the family Euphorbiaceae first described as a genus in 1864. It includes only one known species, Ricinodendron heudelotii, native to tropical Africa from Senegal + Liberia east to Sudan and Tanzania and south to Mozambique and Angola. It produces an economically important oilseed. The tree is known as munguella (Angola), njangsa (Cameroon), bofeko (Zaire), wama (Ghana), okhuen (Nigeria), kishongo (Uganda), akpi, djansang, essang, ezezang and njasang. Two varieties of the tree species are recognized R. heudelotii var. heudelotii in Ghana and R. heudelotii var. africanum in Nigeria and westwards.
Cytisus proliferus, tagasaste or tree lucerne, is a small spreading evergreen tree that grows 3–4 m (10–13 ft) high. It is a well known fertilizer tree. It is a member of the Fabaceae (pea) family and is indigenous to the dry volcanic slopes of the Canary Islands, but it is now grown in Australia, New Zealand and many other parts of the world as a fodder crop.
Jute mallow or nalta jute is a species of shrub in the family Malvaceae. Together with C. capsularis it is the primary source of jute fiber. The leaves and young fruits are used as a vegetable, the dried leaves are used for tea and as a soup thickener, and the seeds are edible.
Farmer-managed natural regeneration (FMNR) is a low-cost, sustainable land restoration technique used to combat poverty and hunger amongst poor subsistence farmers in developing countries by increasing food and timber production, and resilience to climate extremes. It involves the systematic regeneration and management of trees and shrubs from tree stumps, roots and seeds. FMNR was developed by the Australian agricultural economist Tony Rinaudo in the 1980s in West Africa. The background and development are described in Rinaudo's book The Forest Underground.
Faidherbia is a genus of leguminous plants containing one species, Faidherbia albida, which was formerly widely included in the genus Acacia as Acacia albida. The species is native to Africa and the Middle East and has also been introduced to Pakistan and India. Common names include apple-ring acacia, and winter thorn. The South African name is ana tree.
Boscia senegalensis, commonly known as hanza, is a member of the family Capparaceae.
Annona senegalensis, commonly known as African custard-apple, wild custard apple, wild soursop, abo ibobo, sunkungo, and dorgot is a species of flowering plant in the custard apple family, Annonaceae. The specific epithet, senegalensis, translates to mean "of Senegal", the country where the type specimen was collected.
Gliricidia sepium, often simply referred to as its genus name Gliricidia, is a medium size leguminous tree belonging to the family Fabaceae. Common names include quickstick, mata ratón; cacao de nance, cachanance; balo in Panama; piñon Cubano in the Dominican Republic; madreado in Honduras; kakawate in the Philippines; madre xacao, madre cacao, or madre de cacao in the Philippines and Guatemala; madero negro in Nicaragua; undirmari in Marathi; pathal or semmakonna in Malayalam and wetahiriya in Sinhala). It is an important multi-purpose legume tree, with a native range from Mexico to Colombia, but now widely introduced to other tropical zones.
Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface. In the late 1980s, there was a movement to understand the full extent of these subterranean networks. Since then it was found that vascular plants are assisted by fungal networks which grow on the root system to promote water redistribution.
Saba senegalensis, known as weda in the Moore, French, and English languages and ‘’madd’’ in Wolof and ‘’laare’’ in Pulaar, is a fruit-producing plant of the Apocynaceae family, native to the Sahel region of sub-Saharan Africa. It has several common names in various West African Languages. The tree grows predominantly on riverbanks and in woodlands in The Gambia, Guinea-Bissau, Burkina Faso, Senegal, Somalia, Mali and Ivory Coast. It has been observed growing as vine up trees, as a small erect shrub, and oftentimes growing to the size of a large tree.
Calliandra calothyrsus is a small leguminous tree or large shrub in the family Fabaceae. It is native to the tropics of Central America where its typical habitat is wet tropical forests or seasonally dry forests with a dry season of four to seven months, when it may become deciduous. This tree grows to about 6 m (20 ft) and has pinnate compound leaves and flowers with a boss of prominent reddish-purple stamens. It is not very drought-tolerant, and the above-ground parts can be short-lived in case of severe drought lasting many months, but the roots regularly resprout.
