Coccoloba Pubescens
''Coccoloba'' is a genus of 177 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, Central America, and Mexico, 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.

Coccoloba Uvifera
''Coccoloba uvifera'' is a species of tree and flowering plant in the buckwheat family, Polygonaceae. Its common names include seagrape and baygrape. It is native to coastal beaches throughout tropical America and the Caribbean. It has edible fruit, among other uses. Description The bark is grayish with light patches. The leaves are fairly round, sometimes initially brownish, maturing to green and often with red veins. The leaves decompose slowly, turning red before withering. Whitish to greenish flowers are produced on long spikes. In late summer, the plant bears green fruit, about diameter, in large, grape-like clusters. The fruit ripens to purplish-red and contains a hard pit constituting most of its volume. The species is dioecious, with male and female flowers borne on separate plants. Cross-pollination is necessary for fruit to develop, aided by insects including honey bees. Male and female plants can be distinguished by the appearance of their flowers, as males usually ...

Liana
A liana is a long-Plant stem, stemmed Woody plant, woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the Canopy (biology), canopy in search of direct sunlight. The word ''liana'' does not refer to a Taxonomy (biology), taxonomic grouping, but rather a habit of plant growth—much like ''tree'' or ''shrub''. It comes from standard French , itself from an Antilles French dialect word meaning to sheaf (agriculture), sheave. Ecology Lianas are characteristic of Tropical and subtropical moist broadleaf forests, tropical moist broadleaf forests (especially Tropical seasonal forest, seasonal forests), but may be found in temperate rainforests and temperate deciduous forests. There are also temperate lianas, for example the members of the ''Clematis'' or ''Vitis'' (wild grape) genera. Lianas can form bridges in the forest canopy, providing Arboreal locomotion, arboreal animals—including ants and many ot ...

Trioecy
Trioecy , also spelled triecy, is a sexual system characterized by the coexistence of males, females, and hermaphrodites. It has been found in both plants and animals. Like androdioecy and gynodioecy, trioecy is a mixed mating systems. Terminology Trioecy is also called tridioecy and subdioecy . The term trioecy comes from the Neo-Latin word '' Trioecia'', a former order of trioecious plants. Evolution of trioecy Trioecy may be an unstable transient state associated with evolutionary transitioning from gynodioecy to dioecy. In brachiopod species, trioecy usually breaks into androdioecy or gynodioecy. 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 plays an important part in the evolution of trioecy. But one study found that trioecy can be stable under nucleocytoplasmic sex determination. ...

Dioecy
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of 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. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Astringent
An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin '' adstringere'', which means "to bind fast". Astringency, the dry, puckering or numbing mouthfeel caused by the tannins in unripe fruits, lets the fruit mature by deterring eating. Tannins, being a kind of polyphenol, bind salivary proteins and make them precipitate and aggregate, producing a rough, "sandpapery", or dry sensation in the mouth. Smoking tobacco is also reported to have an astringent effect. In a scientific study, astringency was still detectable by subjects who had local anesthesia applied to their taste nerves, but not when both these and the trigeminal nerves were disabled. Uses In medicine, astringents cause constriction or contraction of mucous membranes and exposed tissues and are often used internally to reduce discharge of blood serum and mucous secretions. This can happen with a sore throat, hemorrhages, diarrhe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower. It is a structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile (neither male nor female) tubelike tissue that surrounds the female reproductive structure or developing sporophyte. Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is desc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple fruit, simple dry fruits, dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and Dehiscence (botany), indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encom ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other 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 and culinary 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'' als ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
