Heliamphora Chimantensis
''Heliamphora chimantensis'' is a species of marsh pitcher plant endemic to the Chimantá Massif in Venezuela. Specifically, it has been recorded from Apacará and Chimantá Tepuis.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz (2011). ''Sarraceniaceae of South America''. Redfern Natural History Productions, Poole. It is thought to be more closely related to the southern growing '' H. tatei'' and '' H. neblinae'' than to any of the other species found in the Gran Sabana and its tepuis. All other species known from this region have between 10 and 15 anthers, while ''H. tatei'', ''H. neblinae'' and ''H. chimantensis'' have around 20. However, the anthers of ''H. tatei'' and the closely related ''H. neblinae'' (once thought to be a variety of the former) are 7–9 mm long, while those of ''H. chimantensis'' only reach 5 mm in length.

Heliamphora Neblinae
''Heliamphora neblinae'' is a species of marsh pitcher plant endemic to Cerro de la Neblina, Cerro Aracamuni and Cerro Avispa in Venezuela. It is one of the most variable species in the genus and was once considered to be a variety of '' H. tatei''. It is unclear whether or not there is a consensus regarding its status as a species, with at least a few researchers supporting the taxonomic revision that would elevate both ''H. tatei'' var. ''neblinae'' and ''H. tatei'' f. ''macdonaldae'' to full species status.Rice, Barry A. (2006). ''Growing Carnivorous Plants''. Timber Press: Portland, Oregon.

Carnivorous Plants
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants still generate some of their energy from photosynthesis. Carnivorous plants have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875 Charles Darwin published '' Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have evolved independently at least 12 times in five different orders of flowering plants, and is represented by more than a dozen genera. This classification includes at least 583 species that attract, trap, and kill prey, absorbing the resulting available nutrients. Venus flytrap (''Dionaea muscipula''), pitcher ...

Natural History Of Venezuela
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

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. . Retrieved 10 March 2007. p42 These include the ''flor de mayo'' orchid (''Cattleya mossiae''), the national flower. Venezuela's national tree is the '' arag ...

Anther
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tepui
A tepui , or tepuy (), is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Gran Sabana
La Gran Sabana (, en, The Great Savanna) is a region in southeastern Venezuela, part of the Guianan savanna ecoregion. The savanna spreads into the regions of the Guiana Highlands and south-east into Bolívar State, extending further to the borders with Brazil and Guyana. The Gran Sabana has an area of and is part of the second largest National Park in Venezuela, the Canaima National Park. Only Parima Tapirapecó National Park is larger than Canaima. The average temperature is around 20 °C (68 °F), but at night can drop to 13 °C (55 °F) and in some of the more elevated sites, depending on weather, may drop a bit more. The location offers one of the most unusual landscapes in the world, with rivers, waterfalls and gorges, deep and vast valleys, impenetrable jungles and savannahs that host large numbers and varieties of plant species, a diverse fauna and the isolated table-top mesas locally known as ''tepuis''.

Heliamphora Tatei
''Heliamphora tatei'' (after George Henry Hamilton Tate) is a species of marsh pitcher plant endemic to Cerro Duida, Cerro Huachamacari and Cerro Marahuaca in Venezuela. It is closely related to '' H. macdonaldae'', '' H. neblinae'', and '' H. parva'', and all three have in the past been considered forms or varieties of ''H. tatei''.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz (2011). ''Sarraceniaceae of South America''. Redfern Natural History Productions Ltd., Poole. Like ''H. tatei'', these species are noted for their stem-forming growth habit. Putative natural hybrids between ''H. macdonaldae'' and ''H. tatei'' have been recorded in the southern part of Cerro Duida.Rivadavia, F. (2008)Cerro Duida, Cerro Avispa, Cerro Aracamuni.
