Richeria Grandis
''Richeria grandis'' is a tree species in the family Phyllanthaceae which ranges from the Lesser Antilles to South America. The species is reputed to have aphrodisiac properties. Description ''Richeria grandis'' is a large, evergreen tree with brown bark and a brownish-orange inner bark. It has simple, alternate leaves with an entire margin. The leaves are large, generally long up to long and wide. The species is dioecious—male and female flowers are borne on separate plants. The male inflorescences are long with 3-7 flowers; the female inflorescences are long. The fruit is a capsule, about long. Taxonomy The species was first described by Martin Vahl in 1797. The species was placed in the Euphorbiaceae, but that family was split up after molecular phylogenetics, molecular work showed that the family was polyphyletic. ''Richeria'' was moved into a new family, the Phyllanthaceae, when the subfamily Phyllanthoideae was elevated as a result of this split in the Euphorbiace ...

Dominica
Dominica ( or ; Kalinago: ; french: Dominique; Dominican Creole French: ), officially the Commonwealth of Dominica, is an island country in the Caribbean. The capital, Roseau, is located on the western side of the island. It is geographically situated as part of the Windward Islands chain in the Lesser Antilles archipelago in the Caribbean Sea. Dominica's closest neighbours are two constituent territories of the European Union, the overseas departments of France, Guadeloupe to the northwest and Martinique to the south-southeast. Dominica comprises a land area of , and the highest point is Morne Diablotins, at in elevation. The population was 71,293 at the 2011 census. The island was settled by the Arawak arriving from South America in the fifth century. The Kalinago displaced the Arawak by the 15th century. Columbus is said to have passed the island on Sunday, 3 November 1493. It was later colonised by Europeans, predominantly by the French from the 1690s to 1763. The Frenc ...

Medicinal Plants
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including defense and protection against insects, fungi, diseases, and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, c. 3000 BC. The Ebers Papyrus from ancient Egypt, c. 1550 BC, describes over 850 plant medicines. The Greek physician Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in ''De materia medica'', c. 60 AD; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of useful compounds. These include the common drugs asp ...

Aphrodisiac
An aphrodisiac is a substance that increases sexual desire, sexual attraction, sexual pleasure, or sexual behavior. Substances range from a variety of plants, spices, foods, and synthetic chemicals. Natural aphrodisiacs like cannabis or cocaine are classified into plant-based and non-plant-based substances. There are non-naturally-occurring aphrodisiacs like MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (i.e., psychological or physiological). Aphrodisiacs that contain hallucinogenic properties like Bufotenin have psychological effects on a person that can increase sexual desire and sexual pleasure. Aphrodisiacs that contain smooth muscle relaxing properties like yohimbine have physiological effects on a person that can affect hormone levels and increase blood flow. It is possible that the aphrodisiac effect of a substance is due to the placebo effect. Other substances that impede on areas that aphrodisiacs aim to enhance are classified as an ...

Roupala Montana
''Roupala montana'' is a species of shrub or tree in the family Proteaceae which is native to much of the Neotropics. It is a morphologically variable species with four recognised varieties. The species is used medicinally in Venezuela, and as an aphrodisiac in Trinidad and Tobago and Venezuela. Description The species ranges in size from shrubs to trees, usually tall, but sometimes ranging up to tall. The leaves are usually simple in adult plants, but are occasionally compound. It is an ochlospecies—a species that is highly variable morphologically, and that variability "cannot be satisfactorily accommodated within a formal classification"—with a very wide distribution. Consequently, a large number of species and varieties have been described based on variations between collections. Taxonomy The species was first described by Jean Baptiste Christophore Fusée Aublet in 1775. The name ''Roupala'' was based on ''roupale'', a name used locally in French Guiana. The Latin s ...

Parinari Campestris
''Parinari campestris'' is a species of tree in the plant family Chrysobalanaceae which is native to Trinidad, the Guianas, Venezuela and Brazil. It is reputed to have aphrodisiac properties. Description The species is a tree which grows up to tall. Young branches are hairy but they become hairless as the tree ages. The leaves, which are long and wide, are smooth and shiny on their upper surfaces. The lower surface of the leaves is hairy with prominently raised veins. The stipules are broad at the base but narrowing to a point; they are about long. The flowers are hermaphroditic with five white petals, seven stamens and seven or eight staminodes. The fruit is a fleshy drupe, long and wide. Taxonomy The species was described by Jean Baptiste Christophore Fusée Aublet is 1775, together with '' P. montana''. In his 1972 monograph, Ghillean Prance designated ''P. campestris'' as the type species of the genus due to the fact that Aublet's illustration of ''P. montana'' contains ...

Polypore
Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside (see Delimitation for exceptions). They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and the related corticioid fungi are the most important agents of wood decay, playing a very significant role in nutrient cycling and aiding carbon dioxide absorption by forest ecosystems. Over one thousand polypore species have been described to science, but a large part of the diversity is still unknown even in relatively well-studied temperate areas. Polypores are much more dive ...

Cell Wall
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are absent in many eukaryotes, including animals, but are present in some other ones like fungi, algae and plants, and in most prokaryotes (except mollicute bacteria). A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters. The composition of cell walls varies between taxonomic group and species and may depend on cell type and developmental stage. The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses and pectin. Often, other polymers such as lignin, suberin or cutin are anchored to or embedded in plant cell walls. Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan and agar that are absent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane David
Hurricane David was an extremely deadly hurricane which caused massive loss of life in the Dominican Republic in August 1979, and was the most intense hurricane to make landfall in the country in recorded history. A Cape Verde hurricane that reached Category 5 hurricane status on the Saffir–Simpson hurricane scale, David was the fourth named tropical cyclone, second hurricane, and first major hurricane of the 1979 Atlantic hurricane season, traversing through the Leeward Islands, Greater Antilles, and East Coast of the United States during late August and early September. David was the first hurricane to affect the Lesser Antilles since Hurricane Inez in 1966. With winds of 175 mph (280 km/h), David was one of only 2 storms of Category 5 intensity to make landfall on the Dominican Republic in the 20th century, the other also being Inez, and the deadliest since the 1930 Dominican Republic hurricane, San Zenon, killing over 2,000 people in its path.
