Adansonia Gregorii
''Adansonia'' is a genus of medium-to-large deciduous trees known as baobabs ( or ). The eight species of ''Adansonia'' are native to Africa, Australia, and Madagascar but have also been introduced to other regions of the world, including Barbados, where several of the baobabs there are suspected to have originated from Africa. Other baobabs have been introduced to Asia. A Whole genome sequencing, genomic and Ecology, ecological analysis further suggests that the genus itself originated from Madagascar. The Generic name (biology), generic name ''Adansonia'' honours Michel Adanson, the French naturalist and explorer who provided the first detailed botanical description and illustrations of ''Adansonia digitata''. The baobab, however, is also known as the "upside down tree," a name attributable to the trees' overall appearance and historical myths. Baobabs are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The ...

Adansonia Digitata
''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 (Yemen, Oman). 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. Description African baobabs are trees that often grow as solitary individuals, and are large and distinctive elements of savanna or scrubland vegetatio ...

Dehydration
In physiology, dehydration is a lack of total body water that disrupts metabolic processes. It occurs when free water loss exceeds intake, often resulting from excessive sweating, health conditions, or inadequate consumption of water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over 10% of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs with a 15 and 25% loss of body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration usually resolves with oral rehydration, but severe cases may need intravenous fluids. Dehydration can cause hypernatremia (high levels of sodium ions in the blood). This is distinct from hypovolemia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvales
The Malvales are an Order (biology), order of flowering plants. As circumscribed by Angiosperm Phylogeny Group, APG II-system, the order includes about 6000 species within nine Family (biology), families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae, ''sensu lato'' (in the broad sense), are valued for their wood, with that of ''Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus Cola (plant), ''Cola'') are notable for their high ...

Malvaceae
Malvaceae (), or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include Theobroma cacao, cacao, Cola (plant), cola, cotton, okra, Hibiscus sabdariffa, roselle and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The genera with the largest numbers of species include ''Hibiscus'' (434 species), ''Pavonia (plant), Pavonia'' (291 species), ''Sida (plant), Sida'' (275 species), ''Ayenia'' (216 species), ''Dombeya'' (197 species), and ''Sterculia'' (181 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically Monophyly, monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies ha ...

Bombacoideae
Bombacoideae is a subfamily of the mallow family, Malvaceae. It contains herbaceous and woody plants. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. The flowers are hermaphroditic and actinomorphic; the calyx has 5 sepals united at the base, which are not accompanied by an epicalyx (involucel). The corolla has 5 free petals and an androecium of numerous stamens, typically with free filaments which are not fused in a staminal tube (column). The pollen is smooth and the ovary superior and pluricarpellate. The fruits are schizocarpous or capsular. Genera Classification Some taxa in this subfamily were previously grouped under the now-obsolete family Bombacaceae, as recent phylogenetic research has shown that Bombacaceae as traditionally circumscribed (including tribe Durioneae) is not a monophyletic group. '' Camptostemon'', '' Lagunaria'', '' Pentaplaris'' and '' Uladendron'' might more appropriately be placed in Malvoideae, as might the ...

Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prospero Alpini
Prospero Alpini (also known as Prosper Alpinus, Prospero Alpinio and Latinized as Prosperus Alpinus) (23 November 15536 February 1617) was a Venetian physician and botanist. He travelled around Egypt and served as the fourth prefect in charge of the botanical garden of Padua. He wrote several botanical treatises which covered exotic plants of economic and medicinal value. His description of coffee and banana plants are considered the oldest in European literature. The ginger-family genus ''Alpinia'' was named in his honour by Carl Linnaeus, Carolus Linnaeus. Biography Born at Marostica, a town near Vicenza, the son of Francesco, a physician, Alpini served in his youth for a time in the Duchy of Milan, Milanese army, but in 1574 he went to study medicine at Padua. After taking his doctor's degree in 1578, he settled as a physician in Campo San Pietro, a small town in the Paduan territory. But his tastes were botanical and influenced by Melchiorre Guilandino, and to extend his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibn Battuta
Ibn Battuta (; 24 February 13041368/1369), was a Maghrebi traveller, explorer and scholar. Over a period of 30 years from 1325 to 1354, he visited much of Africa, the Middle East, Asia and the Iberian Peninsula. Near the end of his life, Ibn Battuta dictated an account of his journeys, titled '' A Gift to Those Who Contemplate the Wonders of Cities and the Marvels of Travelling'', commonly known as ''The Rihla''. Ibn Battuta travelled more than any other explorer in pre-modern history, totalling around , surpassing Zheng He with about and Marco Polo with . Name "Ibn Battuta" is a patronymic, literally meaning 'son of a duckling'. His most common full name is given as Abu Abdullah Muhammad ibn Battuta. In his travelogue, '' The Rihla'', he gives his full name as " Shams al-Din Abu ’Abdallah Muhammad ibn ’Abdallah ibn Muhammad ibn Ibrahim ibn Muhammad ibn Yusuf Lawati al- Tanji ibn Battuta".

Stipules
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). They are primarily found among dicots and rare among monocots. Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. At the other end of the scale are species like ''Artocarpus elasticus'' where the stipules can be up to eight inches (twenty cm) in length. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often locate ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.
