Coccoloba Pyrifolia
''Coccoloba'' is a genus of about 120–150 species of flowering plants in the family Polygonaceae, which is native to the Neotropics. There is no overall English name for the genus, although many of the individual species have widely used common names. Range The genus is native to tropical and subtropical regions of the Americas, in South America, the Caribbean and Central America, with two species extending into Florida.Flora of North America''Coccoloba''/ref>Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . Description The species are shrubs and trees, and lianas, mostly evergreen. The leaves are alternate, often large (to very large in some species; up to 2.5m (8 feet) long in ''C. gigantifolia''), with the leaves on juvenile plants often larger and of different shape to those of mature plants. The flowers are produced in spikes. The fruit is a three-angled achene, surrounded by an often brightly coloured fleshy perianth, edible in some species, though ...

Patrick Browne (physician)
Patrick Browne (1720–1790) was an Irish physician and botanist. Career Browne was born in Woodstock, County Mayo in 1720, sent to relatives on Antigua in 1737 and returned to Europe due to ill health after two years. He studied medicine, natural history and especially botany at Reims, Paris, and Leyden, qualifying in 1743. He worked as a physician at St. Thomas's Hospital, London, visited Barbados, Montserrat, Antigua, and St. Kitts in the West Indies and settled as physician in Jamaica in 1746. He corresponded with the botanist Carl Linnaeus, among whose papers were found fragments of articles on venereal diseases and yaws by Browne. His major work, ''The Civil and Natural History of Jamaica'' (1756), illustrated by the botanic artist Georg Dionysius Ehret, contains new names for 104 genera.Patrick Browne author, 1756 - Climatoloy, Medical - 503 pages He retired to Rushbrook, near Claremorris Claremorris (; ) is a town in County Mayo in the west of Ireland, at ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coccoloba Gigantifolia
''Coccoloba gigantifolia'' is a species of flowering plant in the knotweed family Polygonaceae. It is endemic to the Madeira River Basin in the states of Amazonas and Rondonia in the central and southwestern Brazilian Amazon. This species resembles that of ''Coccoloba mollis'' but differs in that it has much larger leaves in its fertile branches. Description ''Coccoloba gigantifolia'' is a tree which grows to about in height and has leaves that can reach in length, and in width, the third largest known leaf among dicotyledonous plants after Gunnera manicata and Victoria boliviana. The petiole is only about in length and thick. In addition to the large leaves, it can be distinguished from its congeners by the species' straight trunk, rarely over thick, with transverse rings, articulated petiole inserted in the ochrea An ochrea (Latin ''ocrea'', greave or protective legging), also spelled ocrea, is a plant structure formed of stipules fused into a sheath surrounding the ...

Trioecy
Trioecy, or subdioecy, is a rare sexual system characterized by the coexistence of males, females, and hermaphrodites. It has been found in both plants and animals. Trioecy is sometimes referred to as a mixed mating system alongside androdioecy and gynodioecy. Evolution of trioecy Many speculate trioecy is a transient state and is often associated with evolutionary transitioning from gynodioecy to dioecy. Other studies show that trioecious populations originated from gonochoristic ancestors which were invaded by a mutant selfing hermaphrodite, creating a trioecious population. It has been suggested that chromosomal duplication is an important part in the evolution of trioecy. Evolutionary stability Trioecy is usually viewed as evolutionarily unstable, but its exact stability is unclear. Like in brachiopod species trioecy usually breaks into androdioecy or gynodioecy. But one study found that trioecy can be stable under nucleocytoplasmic sex determination. Another theoretical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecy
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
