Great thread. Well I'll take tree number one - the easiest of them all!
Adansonia digitata, the baobab, is the most widespread of the Adansonia species on the African continent, found in the hot, dry savannahs of sub-Saharan Africa. It also grows, having spread secondary to cultivation, in populated areas. The northern limit of its distribution in Africa is associated with rainfall patterns; The trees usually grow as solitary individuals, and are large and distinctive trees on the savannah, in the scrub, and near settled areas, with some large individuals living to well over a thousand years of age The tree bears very large, heavy white flowers. The showy flowers are pendulous with a very large number of stamens. They carry a carrion scent and researchers have shown they appear to be primarily pollinated by fruit bats of the subfamily Pteropodinae. The fruits are filled with pulp that dries, hardens, and falls to pieces which look like chunks of powdery, dry bread. The baobab is a traditional food plant in Africa, but is little-known elsewhere. It has been suggested that the vegetable has the potential to improve nutrition, boost food security, foster rural development and support sustainable landcare. Vernacular names Adansonia digitata is known by many names, the most common of which is baobab. It is also known as the 'dead-rat tree' (from the appearance of the fruits), 'monkey-bread tree' (the soft, dry fruit is edible), 'upside-down tree' (the sparse branches resemble roots) and cream of tartar tree. In French, it is known as calebassier du Sénégal and arbre de mille ans; in Portuguese as molambeira, imbondeiro, calabaceira and cabacevre; and in Swahili as mbuyu, mkuu hapingwa, mkuu hafungwa and muuyu. Fruit The African baobab's fruit (6 to 8 inches, or 15 cm to 20 cm long) has twice as much calcium as milk, is high in anti-oxidants, iron and potassium, and has 6 times the vitamin C of an orange. The leaves can be eaten as relish, while the fruit dissolved in milk or water can be used as a drink. The seeds also produce edible oil.
