Cytinaceae
Cytinaceae is a family of parasitic flowering plants. It comprises two genera, '' Cytinus'' and '' Bdallophytum'', totalling ten species. These two genera were formerly placed in the family Rafflesiaceae, order Malpighiales. When they were separated into a new family, it was initially placed in Malpighiales, but it has since been recognised as belonging to order Malvales The Malvales are an Order (biology), order of flowering plants. As circumscribed by Angiosperm Phylogeny Group, APG II-system, the order includes about 6000 species within nine Family (biology), families. The order is placed in the eurosids II, w ....

Cytinus
''Cytinus'' is a genus of parasitic flowering plants. Species in this genus do not produce chlorophyll, but rely fully on its host plant. ''Cytinus'' usually parasitizes ''Cistus'' and ''Halimium'', two genera of plants in the family Cistaceae. It has also been found on ''Ptilostemon chamaepeuce''. Several species are found in the Mediterranean Region, South Africa, with a possibly undescribed species from Madagascar. Biology ''C. capensis'' and ''C. sanguineus'' are dioecious, while ''C. hypocistis'' is monoecious. Nickrent ''et al.'' 2004 ''C. hypocistis'' has been shown to infect mainly '' Halimium halimifolium'' and ''Cistus monspeliensis'' in Portugal. Systematics The genus ''Cytinus'' was previously included in the parasitic family Rafflesiaceae, but is now put into the family Cytinaceae (order Malvales), together with the genus '' Bdallophytum'' with four species. ''Cytinus ruber'' is no longer considered a separate species, but is now a subspecies of ''C. hypocist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bdallophytum
''Bdallophytum'' is a genus of parasitic flowering plants with five described species. It parasitizes on the roots of plants of the genus ''Bursera'', such as ''Bursera simaruba''. The genus is endemic to the Neotropics.Parasiticplants.siu.eduCytinaceae/ref> It was previously placed in ''Rafflesiaceae'', but is now placed in family Cytinaceae, together with the only other genus ''Cytinus''. Some ''Bdallophytum'' species were at one time considered to belong to this latter genus. ''Bdallophytum'' is dioecious. Name The genus name is probably derived from Ancient Greek ''bdell-'' "leech Leeches are segmented parasitism, parasitic or Predation, predatory worms that comprise the Class (biology), subclass Hirudinea within the phylum Annelida.

Cytinus Hypocistis
''Cytinus hypocistis'' is an ant-pollinated species of obligate parasitic plant in the family Cytinaceae having four subspecies, which is parasitic on ''Cistus'' (rock-rose) species. It is found primarily in locations that surround the Mediterranean Sea, and is the type for the genus ''Cytinus''. The binomial has been conserved. Description ''Cytinus hypocistis'' is an endophytic root holoparasite that has no chlorophyll, external roots, leaves, or stems. It is a perennial that spends most of its life completely inside the root tissue of its host, and the flowers of ''Cytinus hypocistis'' are the only component of the parasite that can be seen emerging from the host root during their reproductive season. The sweet smelling inflorescence above ground is visited by many species of ants that pollinate it. Distribution ''Cytinus hypocistis'' is native to Albania; Algeria; Crete; Croatia; Cyprus; Greece; France (including Corsica); Palestine; Italy (including Sardinia and Sicily); ...

Malvales
The Malvales are an Order (biology), order of flowering plants. As circumscribed by Angiosperm Phylogeny Group, APG II-system, the order includes about 6000 species within nine Family (biology), families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae, ''sensu lato'' (in the broad sense), are valued for their wood, with that of ''Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus Cola (plant), ''Cola'') are notable for their high ...

Rafflesiaceae
The Rafflesiaceae are a family of rare parasitic plants comprising 36 species in 3 genera found in the tropical forests of east and southeast Asia, including ''Rafflesia arnoldii'', which has the largest flowers of all plants. The plants are endoparasites of vines in the genus ''Tetrastigma'' (Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue. They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants. Description Flowers Rafflesiaceae flowers mimic rotting carcasses in scent, color, and texture to attract their pollinators, carrion flies. For this reason, some flowers of the family '' Rafflesia'' are nicknamed "corpse flowers". Most members of Rafflesiaceae possess a large, bowl-shaped floral chamber formed by a perianth tube and a diaphragm. This diaphragm is the opening for carrion fly pollinators and is surrounded by attractive sterile organs. Flowers are ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitic Plants
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 resources from the host. These resources can include water, nitrogen, carbon and/or sugars. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achille Richard
Achille Richard was a French botanist, botanical illustrator and physician (27 April 1794 in Paris – 5 October 1852). Biography Achille was the son of the botanist Louis Claude Richard, Louis-Claude Marie Richard (1754–1821). He was a pharmacist in the French navy, and a member of several well-known societies of that time. He became a leading botanist, and his books remain valued for their clarity and precision. On 24 February 1834 he was made a member of the French Academy of Sciences (Botanical Section). He was also a member of the Académie Nationale de Médecine, French National Academy of Medicine. He studied and described several genera of orchids that take his abbreviation in the generic name, among them ''Ludisia''.

Genera
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineag ...

Parasite
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), ...
