Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.
Droseraceae is a family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three extant genera. Representatives of the Droseraceae are found on all continents except Antarctica.
Canaima National Park is a 30,000 km2 (12,000 sq mi) park in south-eastern Venezuela that roughly occupies the same area as the Gran Sabana region. It is located in Bolívar State, reaching the borders with Brazil and Guyana. The park was named a World Heritage Site by UNESCO.
Drosera capensis, commonly known as the Cape sundew, is a small rosette-forming carnivorous species of perennial sundew native to the Cape in South Africa. Because of its size, easy-to-grow nature, and the copious amounts of seed it produces, it has become one of the most common sundews in cultivation, and thus, one of the most frequently introduced and naturalised invasive Drosera species.
Drosera rotundifolia, the round-leaved sundew, roundleaf sundew, or common sundew, is a carnivorous species of flowering plant that grows in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan but is also found as far south as California, Mississippi and Alabama in the United States of America and in New Guinea.
Drosera regia, commonly known as the king sundew, is a carnivorous plant in the sundew genus Drosera that is endemic to a single valley in South Africa. The genus name Drosera comes from the Greek word droseros, meaning "dew-covered". The specific epithet regia is derived from the Latin for "royal", a reference to the "striking appearance" of the species. Individual leaves can reach 70 cm (28 in) in length. It has many unusual relict characteristics not found in most other Drosera species, including woody rhizomes, operculate pollen, and the lack of circinate vernation in scape growth. All of these factors, combined with molecular data from phylogenetic analysis, contribute to the evidence that D. regia possesses some of the most ancient characteristics within the genus. Some of these are shared with the related Venus flytrap (Dionaea muscipula), which suggests a close evolutionary relationship.
Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at least four forms have had or still have specific taxonomic recognition: Drosera peltata subsp. peltata, D. peltata subsp. auriculata, D. foliosa and D. gracilis.
The genus Drosera was divided in 1994 by Seine & Barthlott into three subgenera and 11 sections on the basis of morphological characteristics.
Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.
The Roraima mouse is a species of rodent in the family Cricetidae. It is the only species in the genus Podoxymys. It is found only in Guyana.
Stefania roraimae is a species of frog in the family Hemiphractidae. It is endemic to Guyana. Its type locality is Mount Roraima; it is also known from Mount Ayanganna and Mount Wokomung. It presumably occurs in the adjacent Venezuela and Brazil too.
The tepui foliage-gleaner, also known as the white-throated foliage-gleaner, is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Brazil, Guyana and Venezuela.
The Roraiman flycatcher is a species of bird in the family Tyrannidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
Drosera sect. Ergaleium is a section of 26 species that are erect or scrambling tuberous plants in the genus Drosera. This section represents a natural group and are taxonomically monophyletic.
Drosera glanduligera, commonly known as the pimpernel sundew or scarlet sundew, is a species of carnivorous plant endemic to southern Australia. It is an ephemeral annual plant that grows in the winter and flowers from August to November.
The foothill screech owl is a species of owl in the family Strigidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Suriname, and Venezuela.
Maringma-tepui, also written Mount Maringma and historically known as Mount Marima, is a small tepui of the Pacaraima Mountains in Cuyuni-Mazaruni, Guyana. It is known as Malaima-tepui in the local Akawaio language. Most published sources place it just inside Guyanese territory, very close to the border with Brazil, and around 17 kilometres (11 mi) east of Roraima-tepui. However, the mountain remains the subject of considerable toponymic confusion and its name has been applied to at least one other nearby peak.
Waukauyengtipu is a mountain in South America situated in most part within the boundaries of the Paruima territory in the Cuyuni-Mazaruni Region of Guyana. The major part of its area is approx. 1,520 metres (4,990 ft) with some areas elevated up to approx. 1800m a.s.l., although its actual elevation has never been accurately measured and as for now can only be estimated from satellite imagery. The plateau belongs to the westernmost area in Guyana and is also one of the highest mountains in the country.
