Chañar
''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 ...

Atacama Desert
The Atacama Desert ( es, Desierto de Atacama) is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, just behind some very specific spots within the McMurdo Dry Valleys as well as the only hot true desert to receive less precipitation than the polar deserts, and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies , or if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (''salares''), sand, and felsic lava that flows towards the Andes. The desert owes its extreme aridity to a constant temperature inversion due to the cool north-flowing Humboldt ocean current and to the presence of the strong Pacific anticyclone.

John Gillies (botanist)
John Gillies (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 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 Calton.Gibbs, F. W. (1951). John Gillies, M.D., Traveller and Botanist, 1792–1834.

Geoffraea Decorticans, Fruit
''Geoffroea'' is a rather small genus of wild spiny shrubs or small trees of tropical and subtropical South America. Although it gathers few species, they are highly extended geographically throughout the subcontinent. Each species is well known in its local area, as seen from the varied (and mostly domestic) usage of these trees as food, timber, or fuel. It was recently assigned to the informal monophyletic ''Pterocarpus'' clade within the Dalbergieae The tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae (or Papilionaceae). Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera .... References Dalbergieae Fabaceae genera {{dalbergieae-stub ...

Trees Of Peru
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drought-tolerant Trees
Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions'','' surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline), ROS-scavenging enzymes. The molecular control of drought tolerance is also very complex and is influenced other factors such as environment and the developmental stage of the plant. This control consists ...

Flora Of Northern Chile
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann ...

Chilean Matorral
The Chilean Matorral (NT1201) is a terrestrial ecoregion of central Chile, located on the west coast of South America. It is in the Mediterranean forests, woodlands, and scrub biome, part of the Neotropical realm. Matorral is typically characterized by a temperate Mediterranean climate, with rainy winters and dry summers. It is one of the world's five Mediterranean climate regions, which are all located in the middle latitudes on the west coast of continents. The Mediterranean Basin, the California chaparral and woodlands ecoregion of California and Baja California, the Cape Province of South Africa, and Southwest Australia are the other Mediterranean-climate regions. Setting The Matorral occupies central Chile between 32° and 37° south latitude. The Pacific Ocean lies to the west, and the Chilean Coastal Range lies parallel to the coast. The Chilean Central Valley lies between the Coastal range and the Andes Mountains, which bound the Matorral ecoregion on the east. To the nor ...

Dalbergieae
The tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae (or Papilionaceae). Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids ''sensu lato''. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.

Molasses
Molasses () is a viscous substance resulting from refining sugarcane or sugar beets into sugar. Molasses varies in the amount of sugar, method of extraction and age of the plant. Sugarcane molasses is primarily used to sweeten and flavour foods. Molasses is a major constituent of fine commercial brown sugar. It is also one of the primary ingredients used to distill rum. Sweet sorghum syrup is colloquially called ''sorghum molasses'' in the southern United States. Molasses has a stronger flavour than most alternative syrups. Name The word molasses comes from ''melaço'' in Portuguese, a derivative (intensifier) of ''mel'' (honey) with Latinate roots. Cognates include Ancient Greek μέλι (''méli'') (honey), Latin ''mel'', Spanish ''melaza'' (molasses), Romanian ''miere'' or ''melasă'', and French ''miel'' (honey). Cane molasses Cane molasses is an ingredient used in baking and cooking. It was popular in the Americas before the twentieth century, when it was plentiful and ...
