Bombax buonopozense, commonly known as the Gold Coast bombax or red-flowered silk cotton tree, is a tree in the mallow family. It is also known in the Dagbani language as Vabga (plural Vabsi).
It is native primarily in West Africa, where it is found in rainforests from Sierra Leone in the northwest, east to Uganda and south to Angola, [2] typically at elevations of 900 to 1200 metres. A large tree, it often reaches heights of 40 metres (130 feet) with buttress roots up to 6 metres (20 feet) in diameter. The bark of younger trees is covered with spines and large, deep pink-to-red flowers emerge while the tree is leafless.
Various parts of the plant are used for medicinal purposes, as food, as a source of clothing fibre, as a building material, and as a dye. The fruits are eaten by animals such as the water chevrotain. [3]
Bombax buonopozense is a large tropical pioneer tree that grows to 40 metres (130 feet) in height with large buttress roots that can spread 6 metres (20 feet). The bark is covered in large, conical spines, especially when young, but shedding them with age to some degree. The branches are arranged in whorls. The leaves are compound and have 5 to 9 leaflets and 15 to 25 secondary veins. They are set on long petioles that typically measure between 22 and 14 cm. The individual leaflets have entire margins and are also quite large, measuring from 8 to 23 cm in length by 3 to 7.5 cm in width. The undersides of the leaflets may be either glabrous (i.e. hairless) or puberulous (i.e. very finely haired). The buds are conical. [4]
The conspicuous flowers emerge while the tree is leafless and are either solitary or arranged in small axillary cymes. The truncate calyx, that is the whorl of sepals, is 1 to 1.6 cm high and is cupuliform, or cup-shaped. It is also deciduous, meaning that it does not persist on the fruit. The petals are deep pink or red in colour and are 5.5 to 9.5 cm in length by 2.5 to 3.7 cm in width. The numerous stamens are arranged in bundles with two whorls. A curiosity of these flowers is that they fill with rainwater, and provide a home for aquatic creatures. [5] The fruits are oblong and fairly large, being 8 to 18 cm in length by 3.5 to 6 cm in diameter. They are glabrous, either rigged or angular, and loculicidal, meaning that they open spontaneously at maturity along the capsule wall in between the sections of the locule. They contain many seeds that are 5 to 6 mm in length, all of which have a woolly indument, that is a cotton-like fibre covering. [4]
Two subspecies are accepted: [2]
Many parts of the plant are utilised for medicinal and traditional purposes. In Ghana, where it is native, the leaves are common as fodder for domestic livestock. The bark is burnt to produce a smoke that is believed to drive away evil spirits called alizini in Dagbani. The abundant thorns present on the bark are burnt and the resulting charcoal is mixed with butter to treat swelling. Dried gum produced from the tree is used as an incense. [6] Various parts of the plant have also been used as contraceptives or abortifacients [7] .
The wood is quite light, which limits its uses to canoes and other implements. A dye can be made from the tannins within the bark, while the cotton-like fibre that covers the seeds is gathered and used as a cotton substitute. It cannot be spun, however, so its use is limited to a stuffing for pillows and clothing. Both the flowers and the young fruits are used in food. [4] Various ethnic groups of northern Ghana such as the Mamprusi and Konkomba people dry and grind the flowers' calyces and use them in a soup (comparable to the use of calyces of the Sahelian red-flowered kapok tree, Bombax costatum ).
Ceiba pentandra is a tropical tree of the order Malvales and the family Malvaceae, native to Mexico, Central America and the Caribbean, northern South America, and West Africa. A somewhat smaller variety has been introduced to South and Southeast Asia, where it is cultivated.
Ceiba is a genus of trees in the family Malvaceae, native to tropical and subtropical areas of the Americas and tropical West Africa. Some species can grow to 70 m (230 ft) tall or more, with a straight, largely branchless trunk that culminates in a huge, spreading canopy, and buttress roots that can be taller than a grown person. The best-known, and most widely cultivated, species is Kapok, Ceiba pentandra, one of several trees known as kapok. Ceiba is a word from the Taíno language meaning "boat" because Taínos use the wood to build their dugout canoes.
Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus Bombax. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic point of view, and currently the preference is to transfer most of the erstwhile family Bombacaceae to the subfamily Bombacoideae within the family Malvaceae in the order Malvales. The rest of the family were transferred to other taxa, notably the new family Durionaceae. Irrespective of current taxonomic status, many of the species originally included in the Bombacaceae are of considerable ecological, historical, horticultural, and economic importance, such as balsa, kapok, baobab and durian.
Bombax is a genus of mainly tropical trees in the mallow family. They are native to western Africa, the Indian subcontinent, Southeast Asia, and the subtropical regions of East Asia and northern Australia. It is distinguished from the genus Ceiba, which has whiter flowers.
Ceiba speciosa, the floss silk tree, is a species of deciduous tree that is native to the tropical and subtropical forests of South America. It has several local common names, such as palo borracho, or árbol del puente, samu'ũ, or paineira. In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree". In the USA it often is called the silk floss tree. It belongs to the same family as the baobab; the species Bombax ceiba; and other kapok trees. Another tree of the same genus, Ceiba chodatii, is often referred to by the same common names.
Bombax ceiba, like other trees of the genus Bombax, is commonly known as cotton tree. More specifically, it is sometimes known as Malabar silk-cotton tree; red silk-cotton; red cotton tree; or ambiguously as silk-cotton or kapok, both of which may also refer to Ceiba pentandra.
Kigelia is a genus of flowering plants in the family Bignoniaceae. The genus consists of only one species, Kigelia africana, which occurs throughout tropical Africa. The so-called sausage tree grows a poisonous fruit that is up to 60 cm long, weighs about 7 kg, and resembles a sausage in a casing.
Sambucus canadensis, the American black elderberry, Canada elderberry, or common elderberry, is a species of elderberry native to a large area of North America east of the Rocky Mountains, south to Bolivia. It grows in a variety of conditions including both wet and dry soils, primarily in sunny locations.
