 |  |  | Drosera: Encyclopedia - AbarbareaIn Greek mythology, Abarbarea was a naiad. She was the wife of Bucolion, a son of the Trojan king Laomedon, and had two sons, Aesepus and Pedasus. She was one of the three ancestors of the Tyrians, along with Callirrhoe and Drosera.

Bladderwort - Physical description of the trap.
Authorities agree that the vacuum-driven bladders of Utricularia are the most sophisticated carnivorous trapping mechanism to be found anywhere in the Kingdom of Plants (6). The bladders are usually shaped similarly to broad beans and are to be found attached to the submerged stolons by slender stalks.
The bladder walls are very thin and transparent, but are sufficiently inflexible to maintain the bladder's shape despite the vacuum creat ...

 |  |  | Drosera: Encyclopedia II - Carnivorous plant - Trapping mechanismsThere are five basic trapping mechanisms that have evolved in carnivorous plants. These are:
Pitfall traps (pitcher plants), which trap prey in a rolled leaf that contains a pool of digestive enzymes and/or bacteria;
Flypaper traps, which trap prey using a sticky mucilage;
Snap traps, which trap prey with rapid leaf movements;
Bladder traps, which suck in prey with a bladder that generates an internal vacuum;
Lobster-pot traps, which use inward pointing hair ...

 |  |  | Drosera: Encyclopedia II - Carnivorous plant - CultivationAlthough different species of carnivorous plants have different requirements in terms of sunlight, humidity, soil moisture, etc., there are commonalities.
Most carnivorous plants require rain water, or water that has been distilled, deionised by reverse osmosis, or acidified using sulfuric acid. Common tap or drinking water contains minerals (particularly calcium salts) that will quickly build up and kill the plant. This is because most carnivorous plants have evolved in nutrient-poor, acidic soils and are consequently extreme ...

 |  |  | Drosera: Encyclopedia II - Bladderwort - SpeciesUtricularia is the largest genus of carnivorous plants. It is one of the three genera that make up the Bladderwort family (Lentibulariaceae), along with the butterworts (Pinguicula) and corkscrew plants (Genlisea).
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 now generally accepted.

 |  |  | Drosera: Encyclopedia II - Carnivorous plant - Ecology and modelling of carnivoryCarnivorous plants are widespread but rather rare: there are only about 600 species, out of about 250,000 flowering plants. They are almost entirely restricted to habitats such as bogs, where soil nutrients are extremely limiting, but where sunlight and water are readily available. Only under such extreme conditions is carnivory favoured to an extent that makes the adaptations obvious.
The archetypal carnivore, the Venus flytrap, grows under quite extreme environmental conditions. The soils in which it grows have nitrate and calcium l ...

 |  |  | Drosera: Encyclopedia II - Bladderwort - Distribution and habitatUtricularia can survive almost anywhere where there is fresh water for at least part of the year: only Antarctica and the oceanic islands have no native species. In common with most carnivorous plants, they exploit ecological niches poor in dissolved minerals, where their carnivorous nature gives them a competitive advantage; terrestrial varieties of Utricularia can frequently be found alongside representatives of the carnivorous genera Sarracenia (pitcher plants), Drosera (sundews) and others in very wet areas where continuously m ...

 |  |  | Drosera: Encyclopedia II - Bladderwort - Physical descriptionThe main part of a Bladderwort plant always lies below the surface of its substrate. Terrestrial species sometimes produce a few photosynthetic leaf-shoots which lie unobtrusively flat against the surface of their soil, but in all species only the flowering stems rise above and are prominent. This means that the terrestrial species are generally visible only while they are in flower, although aquatic species can be observed below the surfaces of ponds and streams.

 |  |  | Drosera: Encyclopedia II - Carnivorous plant - EvolutionElucidating the evolution of carnivorous plants is made difficult by the paucity of their fossil record. Very few fossils have been found, and all that do exist are either seed or pollen. However, much can be deduced from the structure of current traps. Pitfall traps are quite clearly derived from rolled leaves. The vascular tissues of Sarracenia show this quite clearly: the keel along the front of the trap contains a mixture of leftward and rightward facing vascular bundles, as would be predicted from the fusion of the edges of an ad ...

 |  |  | Drosera: Encyclopedia II - Carnivorous plant - ClassificationThe classification of all flowering plants is currently in a state of flux. In the Cronquist system, the Droseraceae and Nepenthaceae were placed in the order Nepenthales, based on the radial symmetry of their flowers, and their possession of insect-traps. The Sarraceniaceae was placed either in the Nepenthales, or in its own order, the Sarraceniales. The Byblidaceae, Cephalotaceae, and Roridulaceae were placed in the Saxifragal ...
