Triphysaria
''Triphysaria'' is a genus of five plants in the family Orobanchaceae which are known generally as owl's-clovers. This genus is closely related to the genera ''Castilleja'' and '' Orthocarpus''. ''Triphysaria'' are native to western North America, including a species endemic to California. Description These plants, like those in many other genera in the family, are facultative hemiparasites on other plants. They produce haustoria that tap into the roots of other plants to extract some of the nutrients they need. The plants bear spike inflorescences of pouched, folded flowers that have lips shaped like the beak of an owl Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers a ....

Triphysaria Pusilla
''Triphysaria pusilla'' is a species of flowering plant in the family Orobanchaceae known by the common name dwarf owl's-clover. The plant is native to the west coast of North America from British Columbia to central California from the California Coast Ranges across to the Sierra Nevada. It grows in moist open habitat such as spring-fed grasslands. Description ''Triphysaria pusilla'' is an annual herb producing a hairy brownish or purple-colored, multi-branched stem up to about 20 centimeters in maximum height. Like many species in its family, it is a facultative hemiparasite on other plants, attaching to their roots via haustoria to tap nutrients and water. Its leaves are greenish, red or purple because of the anthocyanin pigments that the plants produce. They are up to 3 centimeters long and divided into a few narrow, pointed lobes. The inflorescence is a spike of minute, tubular flowers. Each flower has a beak-like yellow or purple upper lip and a wider lower lip which is ...

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triphysaria Micrantha
''Triphysaria micrantha'' is a species of flowering plant in the family Orobanchaceae known by the common name purplebeak owl's-clover.

Orobanchaceae
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot fami ...

Friedrich Ernst Ludwig Von Fischer
Friedrich Ernst Ludwig Fischer (20 February 1782, Halberstadt – 17 June 1854) was a Russian botanist, born in Germany. He was director of the St Petersburg botanical garden from 1823 to 1850. In 1804 he obtained his medical doctorate from the University of Halle, afterwards working as director of Count Razumoffsky's botanical garden in Gorenki (near Moscow). In 1808 he produced a catalogue of plants of the garden. In 1823 he was appointed director of the imperial botanical garden in St. Petersburg by Alexander I. Here, he was involved with establishing a herbarium and library, as well as the planning of numerous scientific expeditions into the interior of Russia. During his final years, he served as a medical councillor for the Ministry of the Interior. In 1815, he was elected a corresponding member of the Royal Swedish Academy of Sciences. In 1841, his status was changed to that of foreign member. Selected works * ''Catalogue du Jardin des plantes de S.E. Monsieur le co ...

Castilleja
''Castilleja'', commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family Orobanchaceae (following major rearrangements of the order Lamiales starting around 2001; sources which do not follow these reclassifications may place them in the Scrophulariaceae). They are hemiparasitic on the roots of grasses and forbs. The generic name honors Spanish botanist Domingo Castillejo. Ecology ''Castilleja'' species are eaten by the larvae of some lepidopteran species, including '' Schinia cupes'' (which has been recorded on ''C. exserta'') and ''Schinia pulchripennis'' (which feeds exclusively on ''C. exserta''), and checkerspot butterflies, such as ''Euphydryas'' species.

Orthocarpus
''Orthocarpus'', or owl's-clover, is a genus of flowering plants in the family Orobanchaceae (broomrapes). They are native to North America. A number of species formerly included in ''Orthocarpus'' have been transferred to the genus ''Castilleja'', which includes the plants commonly known as Indian paintbrush. Plants of the genus are generally less than in height. Like their close relatives in genus ''Castilleja'', ''Orthocarpus'' are root hemiparasites, capable of photosynthesis but extracting water and mineral nutrients through attachment to the roots of host plants. Some animal species such as the Edith's checkerspot butterfly use these plants as hosts during ovipositing.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
