Sand Forest
A sand forest is a type of rare subtropical forest region, distinctive due to its unique combination of plant (often rare plant) and animal species, and their restriction to ancient coastal dunes. Sand forests are found in Maputaland in South Africa, as well as parts of the Amazon basin in Brazil, Peru, and Colombia. They are typically composed of clay soils and nutrient poor white sands. These forests are commonly referred to as "sand forests" in the South African regions. However, in Mozambique, they are known as the "Lucauati forests". In the Amazon, they are colloquially known as ''campinaranas'' and ''campinas''. Few studies have been carried out on the sand forests. Those studies that have been conducted, the majority of the research has been on the plant diversity within these forests. Origins There have been no comprehensive studies undertaken in the white sand forests. A full understanding of the process in which they have emerged is lacking. However, it is thought tha ...

Sclerophyll
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaf, leaves, short Internode (botany), internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. The word comes from the Greek ''sklēros'' (hard) and ''phyllon'' (leaf). The term was coined by Andreas Franz Wilhelm Schimper, A.F.W. Schimper in 1898 (translated in 1903), originally as a synonym of xeromorph, but the two words were later differentiated. Sclerophyllous plants occur in many parts of the world, but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and South America. They are prominent throughout Flora of Australia, Australia, parts of Flora of Argentina, Argentina, the Cerrado biogeographic region of Geography of Bolivia, Bolivia, Geography of Paraguay, Paraguay and Flora of Brazil, Brazil, and in the Mediterranean forests, woo ...

Eperua
''Eperua'' is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Detarioideae. The fifteen species belonging to this genus are distributed in the tropical zones of Africa and South America, living in the jungles, often along rivers or streams. The leaves are compound pinnate, with smooth margins, and the fruits are long pods. The wood of ''E. falcata'' is called wallaba and is often used in construction. ''Eperua falcata'' Aubl. occurs in Suriname, French Guiana and Guyana, a 30 m high jungle tree called Wallaba or Bijlhout by the natives. The bark is grey brown, and the leaves pinnately compound with 2-4 pairs of obovate leaflets ~ 18 cm long. The flowers are bell-shaped in terminal or subterminal clusters. They have red petals, 5 fertile and 5 sterile stamens. The pods are up to 30 cm long and 6 cm wide, with 2-5 flat seeds. ''Eperua grandiflora'' : "Itoeri wallaba" also occurs in Suriname and the two Guyanas. ''Eperua r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pachira
''Pachira'' is a genus of tropical trees distributed in Central and South America, Africa and India. They are classified in the subfamily Bombacoideae of the family Malvaceae. Previously the genus was assigned to Bombacaceae. Prior to that the genus was found in the (now obsolete) Sterculiaceae. Some 77 species have been identified. They form small or large trees with digitate leaves, and the fruit an oval woody one-celled capsule opening by a number of divisions and containing many seeds. The genus name is derived from a language spoken in Guyana.Helmut Genaust (1983): Etymologisches Wörterbuch der botanischen Pflanzennamen, 2. Auflage. Birkhäuser Verlag – History Although first named ''Pachira'' by Jean Baptiste Aublet in 1775, Carl Linnaeus the Younger unaware of this separately is said to have called the genus ''Carolinea'' after Princess (or Marchioness) "Sophia Caroline of Baden" in 1782. The principle of precedence gives the authority to Pachira. The M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clusiaceae
The Clusiaceae or Guttiferae Juss. (1789) (''nom. alt. et cons.'' = alternative and valid name) are a family of plants including 13 genera and ca 750 species. Several former members of Clusiacae are now placed in Calophyllaceae and Hypericaceae. They are mostly trees and shrubs, with milky sap and fruits or capsules for seeds. The family is primarily tropical. More so than many plant families, it shows large variation in plant morphology (for example, three to 10, fused or unfused petals, and many other traits). According to the APG III, this family belongs to the order Malpighiales. One feature which is sometimes found in this family, and rarely in others (e.g., Malpighiaceae), is providing pollinators with rewards other than pollen or nectar; specifically, some species offer resin which bees use in nest construction (all three rewards are found in different species of the Clusiaceae). Taxonomic history The family Clusiaceae was divided by Cronquist into two subfamilies: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffea Racemosa Berries
''Coffea'' is a genus of flowering plants in the family Rubiaceae. ''Coffea'' species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste and are often juiced. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. Cultivation and use There are over 120 species of ''Coffea'', which is grown from seed. The two most popular are ''Coffea arabica'' (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and '' Coffea canephora'' (known as "Robusta"), which accounts for about 20–40%. '' C. arabica'' is preferred for its sweeter taste, while ''C. caneph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffea Racemosa
''Coffea racemosa'', also known as racemosa coffee and Inhambane coffee, is a species of flowering plant in the family Rubiaceae. It has naturally low levels of caffeine, less than half of that found in ''Coffea arabica'', and a quarter of that in Robusta coffee. It is endemic to the coastal forest belt between northern KwaZulu-Natal in South Africa and Zimbabwe, found in an area less than in size. It was widely cultivated by the Portuguese during the 1960-1970s in Mozambique, currently there are only two plantations at Ibo Island and in Hluhluwe, which remain. ''Coffea racemosa'' is an open-branched shrub or small tree growing up to tall. It has white to pinkish singular flowers ( in diameter In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for ...) or in few-flowered clusters alo ...

Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Rainforests
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as ''lowland equatorial evergreen rainforest''. True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a sub-set of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical moist broadleaf forest (or tropical wet forest) that also includes the more extensive seasonal tropical forests. Overview Tropical rainforests are characterized by two words: hot and wet. Mean monthly temperatures exceed during all months of the year. Average annual rainfall is no less than and can exceed although it typically lies betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
