Chañar Ladeado
''Geoffroea decorticans'', the chañar, kumbaru, or Chilean palo verde (green wood), is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests (montes or espinales) of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is natural to Bolivia, Chile, Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses. Morphology The common name Chilean palo verde comes from the mottled green color of the trunks but does not seriously resemble '' Cercidium''. The chañar tends to be quite upright with a spreading canopy with both straight and mildly curving trunks. As trees mature the trunks and branches take on a sculptural quality with long longitudinal, irregular ridges and valleys. Along with this undulating trunk, large f ...

John Gillies (c. 1792–1834) was a Scottish naval surgeon who later became an explorer and botanist, travelling extensively in South America. Educated at the University of Edinburgh, he served in the Royal Navy during the Napoleonic Wars. Afflicted by tuberculosis, Gillies left the UK aged 28 for South America in the hope that the climate would improve his fragile health. He spent eight years there, mostly in Argentina, surviving wars, civil unrest, and chronic ill health, sending numerous plants to William Jackson Hooker, Hooker at the Royal Botanic Gardens Kew before returning in 1828. He died aged 42 at Edinburgh on 24 November 1834, his remains interred at Old Calton Cemetery, Calton.Gibbs, F. W. (1951). John Gillies, M.D., Traveller and Botanist, 1792–1834.

Trees Of Uruguay
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
