Hibernaculum (botany)
Hibernaculum (plural ''hibernacula'') is the term often applied to a winter bud of certain aquatic plants, such as the bladderworts (''Utricularia''). The buds are heavier than water, and, being developed at the approach of cold weather, they become detached, sink to the bottom of the pond, and thus survive the winter. In the spring, they enlarge, developing air spaces, rise to the surface, and reproduce their species. New International Encyclopedia Certain terrestrial plants also form hibernacula. These include some temperate sundews (''Drosera'') such as '' D. anglica'', '' D. filiformis'', '' D. intermedia'', '' D. rotundifolia''; and some temperate butterworts (''Pinguicula'') such as '' P. balcanica'', '' P. grandiflora'', '' P. longifolia'', and '' P. vulgaris''. See also * Hibernaculum * Turion (botany) A turion (from Latin turio meaning "shoot") is a type of bud that is capable of growing into a complete plant. A turion may be ...

Drosera Filiformis Hibernacula Darwiniana
''Drosera'', which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. 2 volumes. 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.McPherson, S.R. 2008. ''Glistening Carnivores''. Redfern NaturalHistory Productions Ltd., Poole. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with Drosera rotundifolia which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Both the botanical name (from the Greek δρόσος: ''drosos'' = "dew, de ...

Drosera Rotundifolia
''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. Description The leaves of the common sundew are arranged in a basal rosette. The narrow, hairy, long petioles support round laminae. The upper surface of the lamina is densely covered with red glandular hairs that secrete a sticky mucilage. A typical plant has a diameter of around , with a tall inflorescence. The flowers grow on one side of a single slender, hairless stalk that emanates from the centre of the leaf rosette. White or pink in colour, the five-petalled flowers produce , light b ...

Pinguicula Vulgaris
''Pinguicula vulgaris'', the common butterwort, is a perennial carnivorous plant in the bladderwort family, Lentibulariaceae. Description It grows to a height of 3–16 cm, and is topped with a purple, and occasionally white, flower that is 15 mm or longer, and shaped like a funnel. This butterwort grows in damp environments such as bogs and swamps, in low or subalpine elevations. Being native to environments with cold winters, they produce a winter-resting bud ( hibernaculum). There are three forms originating from Europe: ''P. vulgaris'' f. ''bicolor'' which has petals that are white and purple; ''P. vulgaris'' f. ''albida'' which has all white petals; and ''P. vulgaris'' f. ''alpicola'' which has larger flowers.''The Savage Garden, Revised: Cultivating Carnivorous Plants''. Random House LLC, 2013. The taxonomic status of these forms is not universally recognised - see e.g. The Plant List. Common butterwort is an insectivorous plant. Its leaves have glands that excre ...

Pinguicula Longifolia
''Pinguicula longifolia'', commonly known as the long-leaved butterwort, is a perennial carnivorous subalpine plant of the Central Pyrenees, found on both sides of the border. It catches its prey by using its modified leaves that lie on the ground and have “densely covered stalked glands that bear a droplet of sticky mucilage on its top.” The need to capture arthropods is driven by the lack of nutrients present in the soil. ''P. l.'' subsp. ''longifolia'' obtain their nutrition primarily from flying insects, mainly diptera, which replenished the carnivorous plant with nitrogen. ''P. l.'' subsp. ''longifolia'' grows in wet shady areas and on vertical or overhanging limestone walls. It has been found at altitudes between 700 – 1900 meters. In the spring, the winter buds open and the first carnivorous leaves present themselves. These leaves are then followed by the flowers in early summer. Throughout summer the leaves can grow up to 14 cm in length and have glands prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinguicula Grandiflora
''Pinguicula grandiflora'', commonly known as the large-flowered butterwort, is a temperate insectivorous plant in the Lentibulariaceae family. One distinguishing feature of the species is its flower, which is much larger than the average for the genus. The plant is native to parts of Europe; such as France, Ireland, Spain and Switzerland, It is not native to Great Britain, but has been introduced in a few places in England and Wales Wales ( cy, Cymru ) is a country that is part of the United Kingdom.

Pinguicula
''Pinguicula'', commonly known as the butterworts, is a genus of carnivorous flowering plants in the family Lentibulariaceae. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Of the roughly 80 currently known species, 13 are native to Europe, 9 to North America, and some to northern Asia. The largest number of species is in South and Central America. Etymology The name ''Pinguicula'' is derived from a term coined by Conrad Gesner, who in his 1561 work entitled ''Horti Germaniae'' commented on the glistening leaves: ''"propter pinguia et tenera folia…"'' (Latin ''pinguis'', "fat"). The common name "butterwort" reflects this characteristic. Characteristics The majority of ''Pinguicula'' are perennial plants. The only known annuals are ''P. sharpii'', ''P. takakii'', ''P. crenatiloba'', and ''P. pumila''. All species form stemless rosettes. Habitat Butterworts can be ...

Drosera Intermedia
''Drosera intermedia'', commonly known as the oblong-leaved sundew, spoonleaf sundew, or spatulate leaved sundew, is an insectivorous plant species belonging to the sundew genus. It is a temperate or tropical species native to Europe, southeastern Canada, the eastern half of the United States, Cuba, Hispaniola, and northern South America. Description ''Drosera intermedia'' is a perennial herb which forms a semi-erect stemless rosette of spatulate leaves up to 10 cm tall. Plants in temperate regions undergo dormancy during which they form a winter resting bud called a hibernaculum. As is typical for sundews, the leaf blades are densely covered with stalked mucilaginous glands which secrete a sugary nectar to attract insects. These then become ensnared by the mucilage and, unless they are strong enough to escape, are suffocated or die from exhaustion. The plant then secretes digestive enzymes from sessile glands and later absorbs the resulting nutrient solution to supple ...

Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecological ...

Drosera Filiformis
''Drosera filiformis'', commonly known as the thread-leaved sundew, is a small, insectivorous, rosette-forming species of perennial herb. A species of sundew, it is unusual within its genus in that the long, erect, filiform (thread-like) leaves of this plant unroll in spirals – an arrangement similar to the circinate vernation seen in ferns. Distribution and habitat ''D. filiformis'' occurs naturally in both Canada and the United States; its natural range extends down the eastern seaboard of North America from south western Nova Scotia in the north down through New England to Florida in the south. Cultivation ''D. filiformis'' is frequently cultivated, with a few registered cultivars, such as ''D. filiformis'' var. ''filiformis'' (also known as ''D. filiformis'' typical), ''D. filiformis'' × 'California Sunset' (a hybrid between ''D. filiformis'' var. ''filiformis''. All of these cultivars are grown with similar conditions as most other ''Drosera'' species: mineral-po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosera Anglica
''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 ''Drosera rotundifolia, D. rotundifolia'' and ''Drosera linearis, 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''. Morphology ''Drosera anglica'' is a perennial plant, perennial herb which forms an upright, stemless Rosette (botany), rosette of generally :Image:Leaf morphology no title.png, linear-spatulate leaves. As is typical for sundews, the laminae are densely covered with stalked reddish colored mucilage, mucilaginous glands, each tipped with a clear ...
