Pinguicula Hirtiflora
''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 ...

Pinguicula Moranensis
''Pinguicula moranensis'' is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long. The species was first collected by Humboldt and Bonpland on the outskirts of Mina de Morán in the Sierra de Pachuca of the modern-day Mexican state of Hidalgo on their Latin American expedition of 1799–1804.Zamudio, S. 1999 Based on these collections, Humboldt, Bonpland and Carl Sigismund Kunth ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Pinguicula Lusitanica
''Pinguicula lusitanica'', commonly known as the pale butterwort, is a small butterwort that grows wild in acidic peat bog areas along coastal atlantic western Europe from western Scotland and Ireland south through western England and western France to the Iberian Peninsula and Morocco in north-western Africa. It usually forms rosettes across. It is a perennial plant that sometimes acts as an annual plant as it may die after one growth season. It flowers just months after germinating and produces copious amounts of seed, making it somewhat of a weed for carnivorous plant growers. The flowers are small, pale pink with a yellow centre, and funnel-shaped. It self-pollinates to ensure that it will grow back the following year. Cultivation ''Pinguicula lusitanica'' grows easily in most environments as long as it is not directly exposed to the sun and is kept wet with rainwater. It will feed on any small insects including gnats, fruit flies, ants, small moths, and small mosquito ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heterophyllous
Heteroblasty is the significant and abrupt change in form and function, that occurs over the lifespan of certain plants. Characteristics affected include internode length and stem structure as well as leaf form, size and arrangement. It should not be confused with seasonal heterophylly, where early and late growth in a season are visibly different. This change is different from a homoblastic change which is a gradual change or little change at all, so that there is little difference between the juvenile and adult stages. Some characteristics affected by heteroblastic change include the distance between successive leaves (internode length) and stem structure as well as leaf form, size and arrangement. Heteroblasty is found in many plant families as well as only some species within a genus. This random spread of heteroblastic plants across species is believed to be caused by convergent evolution. The earlier and later stages of development are commonly labeled as juvenile and adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinguicula Alpina
''Pinguicula alpina'', also known as the alpine butterwort, is a species of carnivorous plant native to high latitudes and altitudes throughout Eurasia. It is one of the most widespread ''Pinguicula'' species, being found in mountainous regions from Iceland to the Himalayas. Native to cold climates, it is a temperate species, forming prostrate rosettes of green to red leaves and white flowers in the summer and a tight hibernaculum during a period of winter dormancy in the winter. Like all members of the genus, ''P. alpina'' uses mucilaginous glands covering the surface of its summer leaves to attract, trap, and digest arthropod prey. Description ''Pinguicula alpina'' is a small perennial herb, reaching a height of 5–15 cm (2-6 in.) when in flower. The plant is supported by 1–2 cm (0.4-0.8 in) long roots, which are fleshy, yellow-white and branching.Linnee, in Spec. pl. ed. 1 (1753) 17 ''P. alpina'' is the only temperate ''Pinguicula'' which retains these r ...

Dormancy
Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase ''before'' the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase ''after'' adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are ...
