Utricularia Humboldtii
''Utricularia humboldtii'' is a large perennial carnivorous plant that belongs to the genus ''Utricularia''. Peter Taylor lists it as either an "aquatic-epiphyte", a subaquatic or a terrestrial species. ''U. humboldtii'' is endemic to South America, where it is found in Brazil, Guyana, and Venezuela. It was originally published and described by Robert Hermann Schomburgk in 1840. It is usually found growing in the water-filled leaf axils of some species of bromeliad, including ''Brocchinia micrantha'', '' B. tatei'', and '' B. reducta'' and also plants in the genus '' Orectanthe''. It also grows as an epiphyte on tree trunks or as a subaquatic or terrestrial species in shallow water or wet soil in open savanna. It is found mostly between altitudes of and , though it has been found at altitudes as low as . It has been collected in flower throughout every month of the year.Taylor, Peter. (1989).

Henry Gleason
Henry Allan Gleason (1882–1975) was an American ecologist, botanist, and taxonomist. He was known for his endorsement of the individualistic or open community concept of ecological succession, and his opposition to Frederic Clements's concept of the climax state of an ecosystem. His ideas were largely dismissed during his working life, leading him to move into plant taxonomy, but found favour late in the twentieth century. Life and work Gleason was born in Dalton City, Illinois, and after undergraduate and master's work at the University of Illinois earned a PhD from Columbia University in Biology in 1906. He held faculty positions at the University of Illinois, the University of Chicago and the University of Michigan, before returning to the East Coast, to the New York Botanical Garden in the Bronx, New York, where he remained for the rest of his career, until 1950. In Gleason's early ecological research on the vegetation of Illinois, around 1909-1912, he worked largely wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Venezuela
The flora of Venezuela consists of a huge variety of unique plants; around 38% of the estimated 30,000 species of plants found in the country are endemic to Venezuela. Overall, around 48% of Venezuela's land is forested; this includes over 60% of the Venezuelan Amazon. These rainforests are increasingly endangered by mining and logging activities. Venezuela's habitats range from the Andes mountains in the west to the Amazon Basin rainforest in the south, via extensive Llanos plains and Caribbean coast in the center and the Orinoco River Delta in the east. They include xeric scrublands in the extreme northwest and coastal mangrove forests in the northeast. Its cloud forests and lowland rainforests are particularly rich, for example hosting over 25,000 species of orchids.Dydynski, K; Beech, C (2004). Venezuela'. Lonely Planet. .

Flora Of Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histori ...

Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungi in the South American country. Home to 60% of the Amazon Rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet. It has the most known species of plant Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclud ...s (55,000), freshwater fish (3,000), and mammals (over 689). It also ranks third on the list of countries with the most bird species (1,832) and second with the most reptile species (744). The number of fungal species is unknown but is large.Da Silva, M. and D.W. Minter. 1995. ''Fungi from Brazil recorded by Batista and Co-workers''. Myc ...

Carnivorous Plants Of South America
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats ( felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbiv ...

List Of Utricularia Species
There are around 240 species in the genus ''Utricularia'', belonging to the bladderwort family (Lentibulariaceae). It is the largest genus of carnivorous plants and has a worldwide distribution, being absent only from Antarctica and the oceanic islands. This genus was considered to have 250 species until Peter Taylor reduced the number to 214 in his exhaustive study, ''The genus Utricularia - a taxonomic monograph'', published by HMSO (1989). Taylor's classification is generally accepted, though his division of the genus into two subgenera was soon seen as obsolete. Molecular genetic studies have mostly confirmed Taylor's sections with some modifications (Jobson et al., 2003), but reinstalled the division of the genus in three subgenera. This list follows the subgeneric classification ''sensu'' Müller & Borsch (2005), updated with new information in Müller et al. (2006).

Stolon
In biology, stolons (from Latin '' stolō'', genitive ''stolōnis'' – "branch"), also known as runners, are horizontal connections between organisms. They may be part of the organism, or of its skeleton; typically, animal stolons are external skeletons. In botany In botany, stolons are stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its clones produced from stolons form a single genetic individual, a genet. Morphology Stolons may or may not have long internodes. The leaves along the stolon are usually very small, but in a few ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Genus Utricularia - A Taxonomic Monograph
''The Genus Utricularia: A Taxonomic Monograph'' is a monograph by Peter Taylor on the carnivorous plant genus ''Utricularia'', the bladderworts. It was published in 1989 by Her Majesty's Stationery Office (HMSO) as the fourteenth entry in the ''Kew Bulletin Additional Series''. It was reprinted for The Royal Botanic Gardens, Kew in 1994. Background Taylor's monograph represented the culmination of 41 years of research,Lowrie, A. 2002. ''Nuytsia'' 14(3): 405–410.McPherson, S. R. 2010. ''Carnivorous Plants and their Habitats''. 2 volumes. Redfern Natural History Productions, Poole. which included numerous field trips and herbarium visits (Taylor observed 90 species in habitat and estimated he had examined more than 50,000 herbarium specimens). More than 900 ''Utricularia'' taxon names had to be considered for the revision, the vast majority of which proved to be synonyms.Fleischmann, A. 2012.

Epiphyte
An epiphyte is an organism that grows on the surface of a 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. 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 tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orectanthe
''Orectanthe'' is a genus of flowering plants, in the family Xyridaceae, first described as a genus in 1958. It is native to the tepui of northern South America (Venezuela, Guyana, and northwestern Brazil). It is closely related to ''Abolboda'', and both known species were originally classified as members of ''Abolboda ''Abolboda'' is a genus of flowering plants, traditionally and nowadays (Kubitzki system and APG IV) assigned to family Xyridaceae.

Brocchinia Reducta
''Brocchinia reducta'' is one of a few carnivorous bromeliads. It is native to southern Venezuela, Brazil, Colombia, and Guyana, and is found in nutrient-poor soil. ''B. reducta'' adapts to different environments, when growing on rocks it uses its roots as anchors. Structure ''Brocchinia reducta'', like many other bromeliads, forms a water-storing cup with its tightly overlapping leaves. The leaves surrounding the cup of ''B. reducta'' are coated with loose, waxy scales. These scales are highly reflective of ultraviolet light. Since many insects are attracted to ultraviolet (it is also reflected by many flowers), this is an efficient lure. The water in the cup also emits a sweet odor, which may serve to attract ant Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera.
