Peperomia Vinasiana
''Peperomia vinasiana'' is a species of epiphyte or lithophyte plant from the genus ''Peperomia''. It was first described by Casimir de Candolle and the species was published in the book "''Bulletin de la Société Royale de Botanique de Belgique 30(1): 231. 1891892'". It grows mainly on the wet tropical biomes. Etymology Vinasiana means Vinasian. Vinasian refers to the district of Juan Viñas. Distribution It is endemic to Costa Rica. The type specimen was collected by Henri François Pittier in the district of Juan Viñas. Description Alternate leaves moderately petiolate at the base, cordate, apex abbreviate, acuminate on both sides, glabrous with nine nerves, terminal catkins much exceeding the leaves, ovariorhachi imprinted above obliquely shielded shield with obtuse or subacute apex, ovate berry apex obliquely and obtusely subcutes. It has erect glabrous branches in the dry about 2 millimetres thick leathery texture. Limbs are 8 centimetres long and 4 centimetres wide, i ...

Casimir De Candolle
Anne Casimir Pyramus (or Pyrame) de Candolle (20 February 1836, Geneva – 3 October 1918, Chêne-Bougeries) was a Swiss botanist, the son of Alphonse Pyramus de Candolle. Early life and education He studied chemistry, physics and mathematics in Paris (1853–57), later spending time in England, where he met with Miles Berkeley. In 1859 he visited Algeria, and during the following year, continued his education in Berlin. Afterwards, he returned to Geneva as an assistant and colleague to his father. He married Anna-Mathilde Marcet and they had four children: Raymond Charles de Candolle (1864–1935), Florence Pauline Lucienne de Candolle (1865–1943), Richard Émile Augustin de Candolle (1868–1920) and Reyne Marguerite de Candolle (1876–1958). Career In the field of plant systematics, he used criteria such as stem structure and/or leaf arrangement as a basis of anatomical criteria. As a plant physiologist, he conducted investigations on the movement of leaves, the curlin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glabrousness
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Costa Rica
Costa Rica, officially the Republic of Costa Rica, is a country in Central America. It borders Nicaragua to the north, the Caribbean Sea to the northeast, Panama to the southeast, and the Pacific Ocean to the southwest, as well as maritime border with Ecuador to the south of Cocos Island. It has a population of around five million in a land area of nearly . An estimated people live in the capital and largest city, San José, with around two million people in the surrounding metropolitan area. The sovereign state is a presidential republic. It has a long-standing and stable constitutional democracy and a highly educated workforce. The country spends roughly 6.9% of its budget (2016) on education, compared to a global average of 4.4%. Its economy, once heavily dependent on agriculture, has diversified to include sectors such as finance, corporate services for foreign companies, pharmaceuticals, and ecotourism.

Peperomia Aguacatensis
''Peperomia'' is one of the two large genera of the family Piperaceae. It is estimated that there are at least over 1,000 species, occurring in all tropical and subtropical regions of the world. They are concentrated in South and Central America, but may also be found in southern North America, the Caribbean islands, Africa, Oceania, and southern and eastern parts of Asia. The exact number of species is difficult to determine, as some plants have been recorded several times with different names, and new species continue to be discovered. Peperomias have adapted to many different environments and their appearances vary greatly. Some are epiphytes (growing on other plants) or lithophytes (growing on rock or in rock crevices), and many are xerophytes (drought-tolerant, with thick succulent structures to save water) or possess underground tubers (geophytes). Most species are compact perennial shrubs or vines. Some Peperomias have thick, waxy, succulent leaves and stems; still, others ...

Berry
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit although many pips or seeds may be present. Common examples of berries in the culinary sense are strawberries, raspberries, blueberries, blackberries, white currants, blackcurrants, and redcurrants. In Britain, soft fruit is a horticultural term for such fruits. The common usage of the term "berry" is different from the scientific or botanical definition of a berry, which refers to a fleshy fruit produced from the ovary of a single flower where the outer layer of the ovary wall develops into an edible fleshy portion( pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphyll) at nodes. The main axis of an inflorescence above the peduncle is the rachis, which hosts flowers (as opposed to directly on the peduncle). When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafl ... Referen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.

Henri François Pittier
Henri François Pittier de Fabrega (August 13, 1857 in Bex, Switzerland – January 27, 1950 in Caracas, Venezuela) was a Swiss-born geographer and botanist who started Venezuelan National Park history. Biography He graduated as an engineer from the University of Jena and moved to Costa Rica in 1887, where he founded the Physical Geographic Institute and an herbarium. With Théophile Alexis Durand he edited the exsiccata-like series ''Plantae Costaricenses exsiccatae''. Pittier collected fungi in Costa Rica which was published as a paper in 1896 by Marietta Hanson Rousseau and Elisa Caroline Bommer, and collected spiders that were detailed or described by A. Getaz in a paper in 1893, and collected at various dates and locations in the prior four years. That latter work also mentions a specimen from Greytown (Nicaragua) also collected by H.Pittier. Pittier arrived in Venezuela in 1917, where he classified more than 30,000 plants and devoted many years to studying the flora a ...

Epiphyte
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
