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 ...

Triphysaria Eriantha
''Triphysaria eriantha'' is a species of flowering plant in the family Orobanchaceae, known by the common names johnny-tuck and butter-and-eggs. It is native to California and southwestern Oregon, where it grows in many types of habitats including chaparral, becoming quite common in some areas. Description ''Triphysaria eriantha'' is an annual herb producing a hairy purple stem up to about 35 centimeters in maximum height. Like many species in its family, it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. Its green or purplish leaves are up to 5 centimeters long and are divided into a few narrow, pointed lobes. The inflorescence An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches.

Triphysaria Floribunda
''Triphysaria floribunda'' is a rare species of flowering plant in the family Orobanchaceae known by the common name San Francisco owl's-clover. It is endemic to California, where it is known only from the San Francisco Bay Area. It is limited to coastal regions of Marin, San Francisco, and San Mateo Counties, where it occurs in coastal prairie habitats, sometimes on serpentine soils. Description ''Triphysaria floribunda'' is an annual herb producing a hairy to hairless yellow-brown stem up to about 30 centimeters in maximum height. Like many species in its family it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. Its greenish leaves are up to 4 centimeters long and are divided into several narrow, pointed lobes. The inflorescence An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches.

Triphysaria Versicolor
''Triphysaria versicolor'' is a species of flowering plant in the family Orobanchaceae known by the common name yellowbeak owl's-clover. It is native to the west coast of North America from British Columbia to central California, where it grows in grassland habitat. Description ''Triphysaria versicolor'' is an annual herb producing a green or yellowish stem up to about 60 centimeters in maximum height. Like many species in its family it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. The leaves are up to 8 centimeters long and are divided into a few narrow, pointed lobes. The inflorescence An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of sperma ... is a dense spike of flowers. Each flower has a white corolla 1 or 2 centimeters long ...

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 give ... [...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. It is endemic to California, where it is known from the grasslands of the Central Valley and the foothills to the east and west. It an annual herb producing a hairy, glandular, purple-colored stem up to about 15 centimeters in maximum height. Like many species in its family it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. Its greenish to red-purple leaves are up to 2.5 centimeters long and are sometimes divided into a few narrow, pointed lobes. The inflorescence An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches.

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 di ...
