Nicol Alexander Dalzell
Nicol (or Nicholas) Alexander Dalzell FRSE FLS (21 April 1817 – 18 December 1877) was a Scottish botanist. He was one of the first persons to form the link between forest denudation and the impact of rainfall upon the wider countryside. Life Born in Edinburgh, Scotland, his early education was at the High School in Edinburgh. Dalzell studied divinity (rather than botany) at university, under Rev Thomas Chalmers, and received an M.A. at the University of Edinburgh in 1837. He served as the assistant commissioner of customs, salt and opium in Bombay, India in 1841. In 1862 he became conservator of forests in Bombay and superintendent of the Botanical Gardens in the Bombay Presidency. He published ''The Bombay Flora'' (1861), and other works on Indian botany, and retired in 1870. In 1862 he was elected a fellow of the Royal Society of Edinburgh his proposer being John Hutton Balfour. He lost his savings in the collapse of the Bank of Hindostan, China, and Japan. He reti ...

Sapotaceae
240px, '' Madhuca longifolia'' var. ''latifolia'' in Narsapur, Medak district, India The Sapotaceae are a family (biology), family of flowering plants belonging to the order (biology), order Ericales. The family includes about 800 species of evergreen trees and shrubs in around 65 genera (35-75, depending on generic definition). Their distribution is pantropical. Many species produce edible fruits, or white blood-sap that is used to cleanse dirt, organically and manually, while others have other economic uses. Species noted for their edible fruits include ''Manilkara'' (sapodilla), ''Chrysophyllum cainito'' (star-apple or golden leaf tree), and ''Pouteria'' ('' abiu, canistel, lúcuma'', mamey sapote). ''Vitellaria paradoxa'' (''shi'' in several languages of West Africa and ''karité'' in French; also anglicized as shea) is also the source of an oil-rich nut, the source of edible shea butter, which is the major lipid source for many African ethnic groups and is also used in t ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...

Buttress Root
Buttress roots also known as plank roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence the name buttress) while also gathering more nutrients. Buttresses are tension elements, being larger on the side away from the stress of asymmetrical canopies. The roots may intertwine with buttress roots from other trees and create an intricate mesh, which may help support trees surrounding it. They can grow up to tall and spread for 30 metres above the soil then for another 30 metres below. When the roots spread horizontally, they are able to cover a wider area for collecting nutrients. They stay near the upper soil layer because all the main nutrients are found there. Buttress roots vary greatly in size from barely discernable to many square yards (square meters) of surface. The largest for which there is photographic evidence is a More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aubreville's Model
Aubreville's model is a tree architectural model named after André Aubréville, as he identified this pattern as common in Sapotaceae. It is a monopodial model, and characterized by single axis with rhythmic growth. In this model, each cycle of growth will produce a new group of horizontally arranged branches which themselves develop as sympodial complex axis which support leafy rosettes and flowers. Linnaeus used this feature as a distinctive character while naming the genus ''Terminalia''. References Plant morphology Plant taxonomy {{plant-morphology-stub ...

Palaquium
''Palaquium'' is a genus of about 120 species of trees in the family Sapotaceae. Their range is from India across Southeast Asia, Malesia, Papuasia, and Australasia, to the western Pacific Islands. Description Within their range, ''Palaquium'' species are mostly found in the Philippines and Borneo. In Borneo, many species are recorded in the Malaysian states of Sabah and Sarawak. The leaves are typically spirally arranged and often clustered near twig ends. Flowers are mostly bisexual, though some unisexual instances are known. Fruits are one- or two-seeded with rare instances of several seeds. ''Palaquium'' habitats are coastal, lowland mixed dipterocarp, swamp, and montane forests. Some species, for example ''Palaquium gutta'', are well known for producing gutta-percha Gutta-percha is a tree of the genus ''Palaquium'' in the family Sapotaceae. The name also refers to the rigid, naturally biologically inert, resilient, electrically nonconductive, thermoplastic latex deri ...

Endemic Flora Of The Western Ghats
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1851
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
