Heliamphora Sp. 'Akopán Tepui'
''Heliamphora'' sp. 'Akopán Tepui' is an undescribed taxon of marsh pitcher plant known only from Akopán Tepui in Venezuela, where it grows at elevations of 1800–1900 m.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. ''Sarraceniaceae of South America ''Sarraceniaceae of South America'' is a monograph on the pitcher plants of the genus ''Heliamphora'' by Stewart McPherson, Andreas Wistuba, Andreas Fleischmann, and Joachim Nerz.

It resembles '' H. heterodoxa'' in many respects, but has larger and broader pitchers, narrower tepals, and a smaller nectar spoon.

Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliamphora
The genus ''Heliamphora'' ( or ; Greek: ''helos'' "marsh" and ''amphoreus'' " amphora") contains 23 species of pitcher plants endemic to South America.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. '' Sarraceniaceae of South America''. Redfern Natural History Productions, Poole. The species are collectively known as sun pitchers, based on the mistaken notion that the ''heli'' of ''Heliamphora'' is from the Greek ''helios'', meaning "sun". In fact, the name derives from ''helos'', meaning marsh, so a more accurate translation of their scientific name would be marsh pitcher plants. Species in the genus ''Heliamphora'' are carnivorous plants that consist of a modified leaf form that is fused into a tubular shape. They have evolved mechanisms to attract, trap, and kill insects; and control the amount of water in the pitcher. At least one species ('' H. tatei'') produces its own proteolytic enzymes that allows it to digest its prey without the help of symbiotic bacteria ...

Venezuela
Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It has a territorial extension of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. The Venezuelan government maintains a claim against Guyana to Guayana Esequiba. Venezuela is a federal presidential republic consisting of 23 states, the Capital District and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the n ...

Sarraceniaceae Of South America
''Sarraceniaceae of South America'' is a monograph on the pitcher plants of the genus ''Heliamphora'' by Stewart McPherson, Andreas Wistuba, Andreas Fleischmann, and Joachim Nerz. It was published in September 2011 by Redfern Natural History Productions and covered all species known at the time.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. ''Sarraceniaceae of South America''. Redfern Natural History Productions, Poole. The book is part of a comprehensive two-volume work on the Sarraceniaceae. The other tome, '' Sarraceniaceae of North America'', deals with the genera '' Darlingtonia'' and ''Sarracenia''. Intended as the first volume, ''Sarraceniaceae of South America'' includes an introduction to the family Sarraceniaceae as a whole. Both volumes were nominees for the 2012 CBHL Annual Literature Award, in the Technical Interest category. In addition to the main authors, others who worked on the book include Andy Smith and Wayne Jenski, who produced a number of anatom ...

Heliamphora Heterodoxa
''Heliamphora heterodoxa'' ( el, heteros = other, ''doxa'' = opinion, belief) is a species of Heliamphora, marsh pitcher plant native to Venezuela and adjacent Guyana. It was first discovered in 1944 on the slopes interlinking Ptari-tepui and Sororopán-tepui, Sororopan-tepui and formally described in 1951. This ''Heliamphora'' is closely related to ''Heliamphora glabra, H. glabra'' and the latter was for a long time considered a form of ''H. heterodoxa''. It is one of four ''Heliamphora'' taxon, taxa taxon description, formally described by Julian A. Steyermark. ''Heliamphora heterodoxa'' is known to tolerate slightly higher temperatures compared to other ''Heliamphora'' species, due to its habitats being located in upland wetlands and lower elevation Pantepui habitats (approx. 1200m - 1500m a.s.l.). The plant grows vigorously and exhibits a large, overhanging nectar spoon. Etymology The name "''heterodoxa"'', meaning "variable", was given to the species by J.A. Steyermark w ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

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 ...
