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.

Wistuba
Andreas Wistuba (born 4 March 1967) is a German taxonomist and botanist specialising in the carnivorous plant genus, genera ''Heliamphora'' and ''Nepenthes''. More than half of all known ''Heliamphora'' species have been described by Wistuba. Publications * Nerz, J. & A.

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. The pitchers of ''H. neblinae'' are some of the largest in the genus, occasionally exceeding 50 cm.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz (2011). ''Sarraceniaceae of South America''.

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 ...
