Prosopis Flexuosa
''Prosopis flexuosa'', commonly known as tortuous mesquite and a variety of Spanish vernacular names including ''algarrobo dulce'' and ''algarrobo negro'', is a species of flowering tree in the genus '' Prosopis'' of the family Fabaceae. It is found in arid and semi-arid regions of Argentina, Bolivia and Chile, including the western Gran Chaco and the Monte Desert, where it is a conspicuous and characteristic plant of the region. Its timber is used for construction, charcoal and fuel and its fruits are eaten by humans and livestock. Description ''Prosopis flexuosa'' has several varieties exhibiting different growth forms, appearing either as trees (arboreal form) or shrubs. The arboreal form, ''Prosopis flexuosa'' var. ''flexuosa'' is a medium-sized, deciduous tree growing to a height of up to . It has a short trunk and long branches which often grow horizontally and turn up at the ends. The shrub forms (var. ''depressa'' and ''fruticosa'') consist of numerous branches reaching h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyrame De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggesting tha ...

Larrea Divaricata
''Larrea divaricata'', commonly known as chaparral, is a small evergreen bush in the family Zygophyllaceae. It is native to arid regions of South America, where it is known as ''jarilla'' or ''jarillo''. It was first described in 1800 by the Spanish botanist Antonio José Cavanilles. Description ''Larrea divaricata'' is a slow-growing shrub growing to a maximum height of . The stems are cylindrical. The small, dark green, elliptical leaves are resinous and grow in opposite pairs. The yellow flowers have five petals and appear in October and November. The fruits are dry capsules containing greyish hairs and five seeds. The plant is dispersed when goats eat the leaves and seed capsules in the dry season when little grass is available. Distribution and habitat ''Larrea divaricata'' is endemic to southwestern South America. Its range includes Bolivia, Peru, Chile, and Argentina, especially Patagonia. It is found in open woodland, scrubland, and rough grassland. This plant only gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Chile
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Honey
Honey is a sweet and viscous substance made by several bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, as well as during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected from wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal. This process happens naturally when combustion is incomplete, and is sometimes used in radiocarbon dating. It also happens inadvertently while burning wood, as in a fireplace or wood stove. The visible flame in these is due to combustion of the volatile gases exuded as the wood turns into charcoal. The soot and smoke commonly given off by wood fires result from incomplete combustion of those volatiles. Charcoal burns at a higher temper ...

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suaeda Divaricata
__NOTOC__ ''Suaeda'' is a genus of plants also known as seepweeds and sea-blites. Most species are confined to saline or alkaline soil habitats, such as coastal salt-flats and tidal wetlands. Many species have thick, succulent leaves, a characteristic seen in various plant genera that thrive in salty habitats (halophile plants). There are about 110 species in the genus ''Suaeda''. The most common species in northwestern Europe is ''S. maritima''. It grows along the coasts, especially in saltmarsh areas, and is known in Britain as "common sea-blite", but as "herbaceous seepweed" in the USA. It is also common along the east coast of North America from Virginia northward. One of its varieties is common in tropical Asia on the land-side edge of mangrove tidal swamps. Another variety of this polymorphic species is common in tidal zones all around Australia (''Suaeda maritima var. australis'' is also classed as ''S. australis''). On the coasts of the Mediterranean Sea a common ''Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atriplex Lampa
''Atriplex'' () is a plant genus of about 250 species, known by the common names of saltbush and orache (; also spelled orach). It belongs to the subfamily Chenopodioideae of the family Amaranthaceae ''s.l.''. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination. Description Species of plants in genus ''Atriplex'' are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The leaves are arranged alternately along the branches, rarely in opposite pairs, either sessile or on a petiole, and are sometim ...
