The pitchers of Heliamphora chimantensis are an example of pitfall traps.
The pitchers of Heliamphora chimantensis are an example of pitfall traps. Five basic trapping mechanisms are found in carnivorous plants. Pitfall traps pitcher plants trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria.
Flypaper traps use a sticky mucilage.
Snap traps utilize rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum. Lobster traps, Carnivorous plants known as eel traps, force prey to move towards a digestive organ with inward-pointing hairs.
These traps may be active or passive, depending on whether movement aids the capture of prey. For example, Triphyophyllum is a passive flypaper that secretes mucilage, but whose leaves do not grow or move in response to prey capture. Meanwhile, sundews are active flypaper traps whose leaves undergo rapid acid growthwhich is an expansion of individual cells as opposed to cell division.
The rapid acid growth allows the sundew tentacles to bend, aiding in the retention and digestion of prey.
Pitcher plant Characterized by an internal chamber, pitfall traps are thought to have evolved independently at least six times. Within Carnivorous plants family Bromeliaceaepitcher morphology and carnivory evolved twice Brocchinia and Catopsis.
A passive trap, pitfall traps attract prey with nectar bribes secreted by the peristome and bright flower-like anthocyanin patterning within the pitcher. The linings of most pitcher plants are covered in a loose coating of waxy flakes which are slippery for insects, causing them to fall into the pitcher.
Once within the pitcher structure, digestive enzymes or mutualistic species break down the prey into an absorbable form for the plant. The simplest pitcher plants are probably those of Heliamphorathe marsh pitcher plant.
In this genusthe traps are clearly derived from a simple rolled leaf whose margins have sealed together. These plants live in areas of high rainfall in South America such as Mount Roraima and consequently have a problem ensuring their pitchers do not overflow. To counteract this problem, natural selection has favoured the evolution of an overflow similar to that of a bathroom sink —a small gap in the zipped-up leaf margins allows excess water to flow out of the pitcher.
Heliamphora is limited to South America, but the family contains two other genera, Sarracenia and Darlingtoniawhich are endemic to the Southeastern United States with the exception of one species and California respectively.
Sarracenia is the pitcher plant genus most commonly encountered in cultivation, because it is relatively hardy and easy to grow.
|Carnivorous plant - Wikipedia||Carnivorous plants grow naturally in swampy areas around the world where the water that is constantly running over and below the ground washes the nutrients away in the soil.|

In the genus Sarracenia, the problem of pitcher overflow is solved by an operculumwhich is essentially a flared leaflet that covers the opening of the rolled-leaf tube and protects it from rain. Possibly because of this improved waterproofing, Sarracenia species secrete enzymes such as proteases and phosphatases into the digestive fluid at the bottom of the pitcher; Heliamphora relies on bacterial digestion alone.
The enzymes digest the proteins and nucleic acids in the prey, releasing amino acids and phosphate ions, which the plant absorbs. In at least one species, Sarracenia flavathe nectar bribe is laced with coniinea toxic alkaloid also found in hemlockwhich probably increases the efficiency of the traps by intoxicating prey.
This balloon-like chamber is pitted with areolaechlorophyll -free patches through which light can penetrate. Insects, mostly ants, enter the chamber via the opening underneath the balloon. Once inside, they tire themselves trying to escape from these false exits, until they eventually fall into the tube.
Prey access is increased by the "fish tails", outgrowths of the operculum that give the plant its name. Some seedling Sarracenia species also have long, overhanging opercular outgrowths; Darlingtonia may therefore represent an example of neoteny.
In the hundred or so species of this genus, the pitcher is borne at the end of a tendrilwhich grows as an extension to the midrib of the leaf. Most species catch insects, although the larger ones, such as Nepenthes rajahalso occasionally take small mammals and reptiles.Buy Carnivorous plants grown by Hampshire Carnivorous Plants.

The September issue of CPN is out now. The Carnivorous Plant Newsletter (CPN) is the official publication of the International Carnivorous Plant Society.
It is published in March, June, September, and December. Features of CPN include horticultural articles, research papers, field trip reports, conservation news, book and literature reviews, cultivar descriptions, artwork, meeting.
Plants are distributed each year at the UCD Botanical Conservatory plant sale, and are also available at California Carnivores. The name Pinguicula 'Pirouette' was coined because the neatly overlapping, layered leaves give the impression of a swirling pleated skirt.
