Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the Western Australian Christmas tree), ''Atkinsonia ligustrina'' (from the Blue Mountains of Australia), and '' Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while '' Tristerix aphyllus'' is almost holoparasitic. For a more complete description of the Australian Loranthaceae, seFlora of Australia online, for the Malesian Loranthaceae seFlora of Malesia Originally, Loranthaceae contained all mistletoe species, but the mistletoes of Europe and North America (''Viscum'', ''Arceuthobium'', and ''Phoradendron'') belong to the family Santalaceae. The APG II system 2003 assigns the family to the order Santalales in the clade core eudicots. Phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tristerix Aphyllus
''Tristerix aphyllus'' is a holoparasitic plant species of the genus ''Tristerix'' in the family Loranthaceae. It is endemic to Chile. '' T. aphyllus'' is sometimes called the "cactus mistletoe." It should not be confused with the mistletoe cactus, which is an epiphytic cactus, and not a mistletoe. Description The mistletoe, ''Tristerix aphyllus'', parasitizes two species of cactus, ''Echinopsis chiloensis'' and ''Eulychnia acida'', and in its adult form shows only its flowers and its fruits, bursting forth spectacularly from the columnar cacti which are its hosts. Mauseth (2011) discusses the morphological/anatomical effects of '' T. aphyllus'' on the cactus ''Echinopsis chiloensis''. Taxonomy '' T. aphyllus'' was first described by John Miers in 1830 as ''Loranthus aphyllus'' but with the publication in 1973 of an article by Barlow & Wiens, became ''Tristerix aphyllus'' (author, Tieghem (Tiegh.)). Other synonyms are: * ''Loranthus cactorum'' Hook. & Arn. Bot. Bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mistletoe
Mistletoe is the common name for obligate hemiparasitic plants in the order Santalales. They are attached to their host tree or shrub by a structure called the haustorium, through which they extract water and nutrients from the host plant. The name mistletoe originally referred to the species ''Viscum album'' (European mistletoe, of the family Santalaceae in the order Santalales); it is the only species native to the British Isles and much of Europe. A related species with red rather than white fruits, ''Viscum cruciatum'', occurs in Southwest Spain and Southern Portugal, as well as in Morocco in North Africa and in southern Africa. The genus ''Viscum'' is not native to North America, but ''Viscum album'' was introduced to Northern California in 1900. The eastern mistletoe native to North America, ''Phoradendron leucarpum'', belongs to a distinct genus of the family Santalaceae. European mistletoe has smooth-edged, oval, evergreen leaves borne in pairs along the woody st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atkinsonia
''Atkinsonia'' is a hemi-parasitic shrub with oppositely set, entire leaves and yellowish, later rusty-red colored flowers, that is found in Eastern Australia. It is a monotypic genus, the only species being ''Atkinsonia ligustrina'', and is assigned to the showy mistletoe family, Loranthaceae. It is sometimes called Louisa's mistletoe. Description ''Atkinsonia ligustrina'' is a stout upright evergreen shrub of 1–2 m high, that parasitises on the roots of other woody plants, but photosynthesises for itself. It has twenty four chromosomes (2n=24). Roots The primary roots are long-lived, fleshy, bear many scars, and turn blue when damaged. Secondary roots bearing the taproots (or haustoria) are short-lived and devoid of root hairs. Stems and branches There are numerous red–brown branches that split into smooth branchlets that break easily. Leaves The leaves are oppositely set along the branches, but sometimes apparently randomly positioned if some leaves have ...

Nuytsia
''Nuytsia floribunda'' is a hemiparasitic tree found in Western Australia. The species is known locally as moodjar and, more recently, the Christmas tree or Western Australian Christmas tree. The display of intensely bright flowers during the austral summer coincides with the Christmas season. Description The habit of the species may be a tree, up to 10 metres high, or as a lower shrub form. The rough bark is grey-brown. Flowers are a vivid yellow-orange, appearing sometime between October and January. The inflorescence on each flowering stem may be up to one metre in length. It is a root hemiparasite, is photosynthetic and mainly obtains water and mineral nutrients from its hosts. The haustoria arising from the roots of ''Nuytsia'' attach themselves to roots of many nearby plants and draw water and therefore nutrients from them. Almost all species are susceptible to attack; haustoria have even been found attached to underground cables. In natural settings ''Nuytsia'' withdra ...

Alepis
''Alepis'' is a genus of flowering plants belonging to the family Loranthaceae. It is monotypic, being represented by the single species ''Alepis flavida''. This mistletoe was first described in 1852 as ''Loranthus flavidus'' by Joseph Dalton Hooker, but in 1894 Philippe Édouard Léon Van Tieghem Philippe Édouard Léon Van Tieghem (; 19 April 1839 – 28 April 1914) was a French botanist born in Baillleul in the département of Nord. He was one of the best known French botanists of the latter nineteenth century. Life Van Tieghem's f ... transferred it to the genus, ''Alepis''. Its native range is New Zealand. Conservation status It is currently (2017) declared "At Risk - Declining" under the New Zealand Threatened species system, with the qualifier C(1) implying that there are greater than 10000 mature individuals with an expected decline of from 10% to 70%, and with an area of occupancy which is less than 10,000 ha which is expected to decline by from 10% to 50%.

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 ...

Haustorium
In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients. For example, in mistletoe or members of the broomrape family, the structure penetrates the host's tissue and draws nutrients from it. In mycology, it refers to the appendage or portion of a parasitic fungus (the hyphal tip), which performs a similar function. Microscopic haustoria penetrate the host plant's cell wall and siphon nutrients from the space between the cell wall and plasma membrane but do not penetrate the membrane itself. Larger (usually botanical, not fungal) haustoria do this at the tissue level. The etymology of the name corresponds to the Latin word ''haustor'' meaning ''the one who draws, drains or drinks'', and refers to the action performed by the outgrowth. In fungi Fungi in all major divisions form haustoria. Haustoria take several forms. Generally, on penetration, the fungus increases the surface ar ...
