Balanophoraceae
The Balanophoraceae are a subtropical to tropical family of obligate parasitic flowering plants, notable for their unusual development and formerly obscure affinities. In the broadest circumscription, the family consists of 16 genera. Alternatively, three genera may be split off into the segregate family Mystropetalaceae. The plants are normally found in moist inland forests growing on tree roots and have an above ground inflorescence with the overall appearance of a fungus, composed of numerous minute flowers. The inflorescences develop inside the tuberous underground part of the plant, before rupturing it and surfacing. The plants are monoecious, or dioecious, and the fruits are indehiscent drupes or nuts. The underground portion, which attaches itself to the host, looks like a tuber, and is not a proper root system. The plants contain no chlorophyll. ''Balanophora'' means "bearing an acorn" (from the shape of the female inflorescence). Taxonomy In the classification system of ...

Santalales
The Santalales are an order of flowering plants with a cosmopolitan distribution, but heavily concentrated in tropical and subtropical regions. It derives its name from its type genus ''Santalum'' (sandalwood). Mistletoe is the common name for a number of parasitic plants within the order. Overview Many of the members of the order are parasitic plants, mostly hemiparasites, able to produce sugars through photosynthesis, but tapping the stems or roots of other plants to obtain water and minerals; some (e.g. ''Arceuthobium'') are obligate parasites, have low concentrations of chlorophyll within their shoots (1/5 to 1/10 of that found in their host's foliage), and derive the majority of their sustenance from their hosts' vascular tissues (water, micro- and macronutrients, and sucrose). Most have seeds without testae (seed coats), which is unusual for flowering plants. Classification The APG IV system of 2016 includes seven families. As in the earlier APG III system, it was ...

Dactylanthus Taylorii
''Dactylanthus taylorii'', commonly known in English as wood rose and in Māori as te pua o te rēinga, is a fully parasitic flowering plant, the only one endemic to New Zealand. The host tree responds to the presence of ''Dactylanthus'' by forming a burl-like structure that resembles a fluted wooden rose (hence the common name). When the flowers emerge on the forest floor, they are pollinated by a ground-foraging species of native bat. Description ''Dactylanthus taylorii'' is a round, warty, tuber-like stem (up to 50cm wide) or haustorium with no roots, which draws nutrients from the roots of its host. Its leaves do not photosynthesise, and are reduced to floral bracts. Some plants have been aged in excess of 30 years old. ''Dactylanthus'' prefers damp but not waterlogged soil, and is often found at the head of small streams. It parasitises about 30 species of native hardwood trees and shrubs, preferring those growing in secondary forest on the margin of mature podocarp forest ...

Corynaea (plant)
''Corynaea crassa'', commonly known as Peruvian Viagra or ''huanarpo macho'' is a species of parasitic flowering plant in the family Balanophoraceae found in South and Central America. Described in 1856 by Joseph Dalton Hooker, it is the sole member of the monotypic genus ''Corynaea''. It is not specialized for a single host species, with a broad variety of plant species that can serve as a host. Across its broad distribution, it has been known to parasitize at least four separate families of plants and grow in association with various other plants depending on its location. Consisting of a single underground haustorial tuber which is physically connected to the host plant, the inflorescences emerge from the ground seasonally. In Peru, its tubers often find use in the context of folk medicine as an anti-inflammatory and aphrodisiac. Taxonomy First described by Joseph Dalton Hooker in 1856, its initial description was published in ''Transactions of the Linnean Society of London''. ...

Balanophora
''Balanophora'' is a genus of parasitic plants in the family Balanophoraceae found in parts of tropical and temperate Asia, including the Eastern Himalayas, Malesia region, Pacific Islands, Madagascar, and tropical Africa. There are about 20 accepted species, including the newly discovered ''B. coralliformis''. Many species emit an odour which possibly attracts pollinators in the same way that pollinators are attracted to ''Rafflesia''. ''Balanophora'' species are used in folk medicine in many Asian cultures. For example, in Taiwan and China, ''Balanophora'' is known as ''she-gu'' (stone-fungus) and in Thailand as ''hoh-ra-tao-su-nak''. In both cases, the plant is used to treat a variety of ailments and has various ritual purposes. The tubers of ''Balanophora'' are rich in a wax-like substance which is used in Java as a fuel for torches. Taxonomy The genus was first described in 1775 by Johann Reinhold Forster and his son Georg Forster in '' Characteres Generum Plantarum''. T ...

Hachettea
''Hachettea austrocaledonica'' is a species of parasitic plant in the Balanophoraceae family. It is endemic to New Caledonia and the only species of the genus ''Hachettea''. Its closest relative is '' Dactylanthus'' from New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count ....Su, Huei-Jiun, Jer-Ming Hu, Frank E.

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.

Chlorophyll
Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words , ("pale green") and , ("leaf"). Chlorophyll allow plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll ''a'' and ''b''. History Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817. The presence of magnesium in chlorophyll was discovered in 1906, and was that element's first detection in living tissue. After initial work done by German chemi ...

Olacaceae
Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world. , the circumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families. Taxonomy The 1998 APG system and the 2003 APG II system assign it to the order Santalales in the clade core eudicots. Prior to the advent of molecular data, the circumscription of the family Olacaceae varied widely between different authorities.Valéry Malécot and Daniel L. Nickrent. 2008. "Molecular Phylogenetic Relationships of Olacaceae and Related Santalales". ''Systematic Botany'' 33(1):97-106. Among these various classifications, about 30 genera were included in the family. 15 genera are recognized for Olacaceae by the Germplasm Resources Information Network. The phylogenetic investigation published in 2008 recovered seven clades that were well-supported by molecular and morphological characters, but no for ...
