Orobanche
''Orobanche'', commonly known as broomrape, is a genus of over 200 species of small parasitic herbaceous plants, mostly native to the temperate Northern Hemisphere. It is the type genus of the broomrape family Orobanchaceae. Description Broomrapes are generally small, only tall depending on species. They are best recognized by the yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of 10-20 flowers in most species, although single in one-flowered broomrape (''Orobanche uniflora''). The leaves are merely triangular scales. The seeds are minute, tan or brown, blackening with age. These plants generally flower from late winter to late spring. When they are not flowering, no part of the plants is visible above the surface of the soil. Parasitism As they have no chlorophyll, the broomrapes are totally dependent on other plants for nutrients. Broomrape seeds ...

Orobanche Uniflora
''Orobanche uniflora'', commonly known as one-flowered broomrape, one-flowered cancer root, ghost pipe or naked broomrape, is an annual parasitic herbaceous plant. It is native to much of North America, where it is a parasitic plant, tapping nutrients from many other species of plants, including those in the families Asteraceae and Saxifragaceae and in the genus ''Sedum''. The name "orobanche" can be translated to "vetch-strangler" and "uniflora" can be translated to "single-flower". Description ''Orobanche uniflora'' grows to in height, with one purple-to-white flower with five petals per stem. The corolla is two-lipped, finely fringed with five similar lobes. The main stem is under the ground, with only the pedicels being seen and each pedicel containing only one flower. The stems are grayish tan. No leaves are on the plant or offshoot from it. It reproduces from its seeds, which are produced from fruit that has two sections. Many seeds are produced from the plant's fruit. Th ...

Orobanche Hederae
''Orobanche hederae'', the ivy broomrape, is, like other members of the genus ''Orobanche'', a parasitic plant without chlorophyll, and thus totally dependent on its host, which is ivy. It grows to , with stems in shades of brown and purple, sometimes yellow. The flowers are long, cream in colour with reddish-purple veins. Etymology ''Orobanche'' is derived from Greek, and means 'bitter vetch strangler'. This name originates from the species '' Orobanche rapum-genistae'', which parasitizes legumes. The name ''hederae'' means 'of ivy', in reference to its host plant, ''Hedera''. Common names in English include ivy broomrape and chokeweed. It is also called ''erva-toira da hera'' in Portuguese and ''orobanche du lierre'' in French. Description Its yellowish to purplish stems are usually strongly swollen at the base and by . They are covered in short soft glandular hairs. Leaves are acute and oblong to lance-shaped. It's calyx (sepals) are with free segments that are entire or u ...

Orobanche Minor
''Orobanche minor'', the hellroot, common broomrape, lesser broomrape, small broomrape or clover broomrape, is a holoparasitic flowering plant belonging to the family Orobanchaceae. It is one of about 150 non-photosynthetic plants in the genus ''Orobanche'' that parasitize autotrophic plants. Characteristics and growth requirements ''Orobanche minor'' grows to and is a perennial. The flowers are hermaphrodite. Common broomrape grows in a wide variety of soils, namely moist, light (sandy), medium (loamy) and heavy (clay) soils that are acid, neutral or basic. It can grow in semi-shade or in full sunlight. The species appears in a wide range of colours from red-brown, yellow-brown to purple. Yellow specimens are also not uncommon and it is this extreme variability that makes identification on the basis of size or colour uncertain. It is parasitic on various members of the pea (Fabaceae) and daisy (Asteraceae) families. Although widespread, its appearance is sporadic; despite ...

Orobanche Ramosa
''Orobanche ramosa'' is a species of broomrape known by the common names hemp broomrape and branched broomrape. It is native to Eurasia and North Africa, but it is known in many other places as an introduced species and sometimes a noxious weed. It is a pest in agricultural fields, infesting crops including tobacco, potato, and tomato. The plant produces many slender, erect stems from a thick root. The yellowish stems grow 10 to 60 centimeters tall and are coated in glandular hairs. The broomrape is parasitic on other plants, draining nutrients from their roots, and it lacks leaves and chlorophyll. The inflorescence bears several flowers, each in a yellowish calyx of sepal A sepal () is a part of the flower of angiosperms (flowering plants).

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] |
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 ...

Orobanche Crenata
''Orobanche crenata'' is a species of broomrape, commonly known as bean broomrape. It is a common parasite of the faba bean, ''Vicia faba''. It is native to the Mediterranean basin in Europe and North Africa, the Arabian Peninsula, and Western Asia through to Iran. It has been introduced elsewhere, including Ethiopia. It has no chlorophyll, and gets its carbohydrates from the host's phloem, and water and minerals from the host's xylem. It is a constant threat to legume A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse.

Fava Bean
''Vicia faba'', commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieties with smaller, harder seeds that are fed to horses or other animals are called field bean, tic bean or tick bean. Horse bean, ''Vicia faba'' var. ''equina'' Pers., is a variety recognized as an accepted name. This legume is very common in Southern European, Northern European, East Asian, Latin American and North African cuisines. Some people suffer from favism, a hemolytic response to the consumption of broad beans, a condition linked to a metabolism disorder known as G6PDD. Otherwise the beans, with the outer seed coat removed, can be eaten raw or cooked. In young plants, the outer seed coat can be eaten, and in very young plants, the seed pod can be eaten.

Coleus
''Coleus'' is a genus of annual or perennial herbs or shrubs, sometimes succulent, sometimes with a fleshy or tuberous rootstock, found in the Old World tropics and subtropics. The relationship among the genera ''Coleus'', '' Solenostemon'' and '' Plectranthus'' has been confused. ''Coleus'' and ''Solenostemon'' were sunk into ''Plectranthus'', but recent phylogenetic analysis found ''Plectranthus'' to be paraphyletic with respect to other related genera in the subtribe Plectranthinae. The most recent taxonomic treatment of the genus resurrected ''Coleus'', and 212 names were changed from combinations in ''Plectranthus'', ''Pycnostachys'' and ''Anisochilus''. ''Equilabium'' was segregated from ''Plectranthus'', after phylogenetic studies supported its recognition as a phylogenetically distinct genus. ''Coleus'' are cultivated as ornamental plants, particularly ''Coleus scutellarioides'' (syns. ''Coleus blumei'', ''Plectranthus scutellarioides''), which is popular as a garden p ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
