Adansonia is a genus made up of eight species of medium-to-large deciduous trees known as baobabs. They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia. The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk, opening so quickly that movement can be detected by the naked eye, and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.
Adansonia gregorii, commonly known as the boab and also known by a number of other names, is a tree in the family Malvaceae, endemic to the northern regions of Western Australia and the Northern Territory of Australia.
Adansonia digitata, the African baobab, is the most widespread tree species of the genus Adansonia, the baobabs, and is native to the African continent and the southern Arabian Peninsula. These are long-lived pachycauls; radiocarbon dating has shown some individuals to be over 2,000 years old. They are typically found in dry, hot savannas of sub-Saharan Africa, where they dominate the landscape and reveal the presence of a watercourse from afar. They have traditionally been valued as sources of food, water, health remedies or places of shelter and are a key food source for many animals. They are steeped in legend and superstition. In recent years, many of the largest, oldest trees have died, for unknown reasons. Common names for the baobab include monkey-bread tree, upside-down tree, and cream of tartar tree.
Adansonia rubrostipa, commonly known as fony baobab, is a deciduous tree in the Malvaceae family. Of eight species of baobab currently recognized, six are indigenous to Madagascar, including fony baobab. It is endemic to western Madagascar, found in Baie de Baly National Park, south. It is associated with well-drained soils and is found in dry and spiny forests. It occurs in the following protected areas: Amoron'i Onilahy, Baie de Baly, Menabe Antimena, Mikea, Namoroka, Ranobe PK 32, Tsimanampesotse, Tsimembo Manambolomaty, Tsinjoriake.
Pachycauls are plants with a disproportionately thick trunk for their height, and few branches. In contrast, trees with thin twigs such as Oak (Quercus), Maple (Acer) and Eucalyptus are called leptocauls while those with moderately thick twigs like Plumeria are called mesocauls. Pachycauly can be the product of exceptional primary growth or disproportionate secondary growth as with the Baobabs (Adansonia). The word is derived from the Greek pachy- meaning thick or stout, and Latin caulis meaning the stem. All of the tree species of cactus are pachycauls, as are most palms, Cycads and pandans. The most extreme pachycauls are the floodplains, or riverbottom variety of the African Palmyra with primary growth up to seven feet in thickness, and the Coquito Palm with primary growth up to six feet thick. The most pachycaulous cycad is Cycas thouarsii at up to five feet in diameter. The tallest pachycaul is the Andean Wax Palm at up to 220 feet. and about 16 inches (41 cm) in diameter. The most pachycaulous cactus is the Bisnaga with primary growth up to 4 ft 4 in in diameter. The largest caudex type pachycaul is the African Baobab. One called the Glencoe Baobab at Hoedspruit, South Africa has a basal diameter of 52 ft 2 in. This tree suffered a severe trauma and is dying.
Adansonia grandidieri is the biggest and most famous of Madagascar's six species of baobabs. It is sometimes known as Grandidier's baobab or the giant baobab. In French it is called Baobab malgache. The local name is renala or reniala. This tree is endemic to the island of Madagascar, where it is an endangered species threatened by the encroachment of agricultural land. This is the tree found at the Avenue of the Baobabs.
Adansonia za is a species of baobab in the genus Adansonia of the family Malvaceae. It was originally named in French as anadzahé. Common names in Malagasy include bojy, boringy, bozy, bozybe, ringy, and za, the last of which gives the plant its specific epithet. Eight Adansonia species are recognized, with six endemic to Madagascar. Adansonia za is the most widespread of the Madagascar endemics.
