Mistletoe In White Poplar 1
Mistletoe is the common name for obligate parasite, obligate parasitic plant, hemiparasitic plants in the Order (biology), 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 separate species, ''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. European mistletoe has smooth-edged, oval, evergreen leaves borne in pairs along the woody stem, and waxy, white berries that it bears in clusters of two to six. The Eastern mistletoe of North America is s ...

''Viscum album'' is a species of mistletoe in the family Santalaceae, commonly known as European mistletoe, common mistletoe or simply as mistletoe (Old English ''mistle'').D. Zuber (2004). Biological flora of Central Europe: ''Viscum album'' L. Flora 199, 181-203 It is native to Europe and western and southern Asia. ''Viscum album'' is a hemiparasite on several species of trees, from which it draws water and nutrients. It has a significant role in European mythology, legends, and customs. In modern times, it is commonly featured in Christmas decoration and symbology. (''V. album'' is found only rarely in North America, as an introduced species; its cultural roles are usually fulfilled by the similar native species ''Phoradendron leucarpum''.) Description It is a parasitic plant, hemi-parasitic evergreen shrub, which grows on the stems of other trees. It has stems long with dichotomous branching. The leaf, leaves are in opposite pairs, strap-shaped, entire, leathery textured, ...

Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family (biology), family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them Parasitic plant, hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the Western Australian Christmas tree), ''Atkinsonia ligustrina'' (from the Blue Mountains (New South Wales), Blue Mountains of Australia), and ''Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustorium, haustoria may sometimes tap the phloem, while ''Tristerix aphyllus'' is almost Parasitic plant, 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.

Santalales
The Santalales are an order (biology), 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, micronutrient, micro- and macronutrients, and sucrose). Most have seeds without testa (botany), testae (seed coats), which is unusual for flowering plants. Classification The APG IV system of 2016 includes seven familie ...
