Calyptronoma Rivalis
''Calyptronoma rivalis'' is a pinnately compound leaved palm species that is native to the Caribbean islands of Hispaniola (in both Haiti and the Dominican Republic) and Puerto Rico. Its common names include palma de manaca and Puerto Rican manac. Taxonomy In 1995, botanists revised the taxonomy of the genus ''Calyptronoma'', placing ''Calyptronoma quisqueyana'' in synonymy with the rare palm.USFWSPalma de Manaca: Five-year Review.2007.Zona, S. (1995). A Revision of ''Calyptronoma'' (Arecaceae). ''Principles'' 39(3): 140-151. Then the species included all of the individuals previously named ''C. quisqueyana'', extending its distribution to the island of Hispaniola, where it is common. Description ''C. rivalis'' stems grow singly, and reach heights of 4–15 m, with stems 15–30 cm in diameter. It grows in waterlogged areas near the banks of streams; on Hispaniola, it occurs at less than 450 m above sea level, and ''Calyptronoma plumeriana'' replaces it above that elevatio ...

Spathodea
''Spathodea'' is a genus in the plant family Bignoniaceae. The single species it contains, ''Spathodea campanulata'', is commonly known as the African tulip tree. The tree grows between tall and is native to tropical dry forests of Africa. It has been nominated as among 100 of the "World's Worst" invaders. This tree is planted extensively as an ornamental tree throughout the tropics and is much appreciated for its very showy reddish-orange or crimson (rarely yellow), campanulate flowers. The generic name comes from the Ancient Greek words σπαθη (''spathe'') and οιδα (''oida''), referring to the spathe-like calyx. It was identified by Europeans in 1787 on the Gold Coast of Africa. Description The flower bud is ampule-shaped and contains water. Children sometimes play with these buds because of their ability to squirt water. The sap sometimes stains yellow on fingers and clothes. The open flowers are cup-shaped and hold rain and dew, making them attractive to many spec ...

Flowers are Showy pink, tubular and five lobed (2 to 3 inches long). The flowering time is spring and Summer. Fruit is a seedpod, it splits along 2 lines to shed the numerous thin light brown seeds (1/2 to 1 inch long with 2 white wings).

Delonix Regia
''Delonix regia'' is a species of flowering plant in the bean family Fabaceae, subfamily Caesalpinioideae native to Madagascar. It is noted for its fern-like leaves and flamboyant display of orange-red flowers over summer. In many tropical parts of the world it is grown as an ornamental tree and in English it is given the name royal poinciana, flamboyant, phoenix flower, flame of the forest, or flame tree (one of several species given this name). This species was previously placed in the genus ''Poinciana'', named for Phillippe de Longvilliers de Poincy, the 17th-century governor of Saint Christopher (Saint Kitts). It is a non-nodulating legume. Description The flowers of ''Delonix regia'' are large, with four spreading scarlet or orange-red petals up to long, and a fifth upright petal called the standard, which is slightly larger and spotted with yellow and white. They appear in corymbs along and at the ends of branches. The naturally occurring variety ''flavida'' (Beng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or skeletons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calcarenite
Calcarenite is a type of limestone that is composed predominantly, more than 50 percent, of detrital (transported) sand-size (0.0625 to 2 mm in diameter), carbonate grains. The grains consist of sand-size grains of either corals, shells, ooids, intraclasts, pellets, fragments of older limestones and dolomites, other carbonate grains, or some combination of these. Calcarenite is the carbonate equivalent of a sandstone. The term calcarenite was originally proposed in 1903 by GrabauGrabau, A.W. (1903) ''Paleozoic coral reefs.'' Geological Society of America Bulletin. vol. 14, pp. 337-352.Grabau, A.W. (1904) ''On the classification of sedimentary rocks.'' American Geologist. vol. 33, pp. 228-247. as a part of his calcilutite, calcarenite and calcirudite carbonate classification system based upon the size of the detrital grains composing a limestone.Flügel, E.

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
