Phoradendron leucarpum is a species of mistletoe in the Viscaceae family which is native to the United States and Mexico. Its common names include American mistletoe, eastern mistletoe, hairy mistletoe and oak mistletoe. It is native to Mexico and the continental United States. [3] It is hemiparasitic, living in the branches of trees. The berries are white and 3–6 millimeters (0.12–0.24 in). [4] [5] It has opposite leaves that are leathery and thick. [6] Ingesting the berries can cause "stomach and intestinal irritation with diarrhea, lowered blood pressure, and slow pulse". [4] [7] This shrub can grow to 1 meter (3.3 ft) by 1 meter (3.3 ft). [7]

Culture and tradition

Phoradendron leucarpum is used in North America as a surrogate for the similar European mistletoe Viscum album , in Christmas decoration and associated traditions (such as "kissing under the mistletoe"), as well as in rituals by modern druids. It is commercially harvested and sold for those purposes. [8]

Phoradendron leucarpum is the state floral emblem for the state of Oklahoma. The state did not have an official flower, leaving mistletoe as the assumed state flower until the Oklahoma Rose was designated as such in 2004. [9]

Ecology

Over 60 species of trees are hosts to P. leucarpum, especially trees in the genera of Acer (maple), Fraxinus (ash), Juglans (walnuts), Nyssa , Platanus (plane trees), Populus (poplars), Quercus (oaks), Salix (willows), and Ulmus (elms). [2]

Wildlife

While the sticky substance covering the fruits is toxic to humans, it is a favorite of some birds. [10]

<span class="mw-page-title-main">Mistletoe</span> Common name for various parasitic plants that grow on trees and shrubs

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.

<i>Berberis aquifolium</i> Species of flowering plant

Berberis aquifolium, the Oregon grape or holly-leaved barberry, is a species of flowering plant in the family Berberidaceae, native to western North America. It is an evergreen shrub growing 1–3 meters tall and 1.5 m (5 ft) wide, with pinnate leaves consisting of spiny leaflets, and dense clusters of yellow flowers in early spring, followed by dark bluish-black berries.

<i>Ilex opaca</i> Species of holly

Ilex opaca, the American holly, is a species of holly, native to the eastern and south-central United States, from coastal Massachusetts south to central Florida, and west to southeastern Missouri and eastern Texas.

<i>Quercus virginiana</i> Species of oak tree

Quercus virginiana, also known as the southern live oak, is an evergreen oak tree endemic to the Southeastern United States. Though many other species are loosely called live oak, the southern live oak is particularly iconic of the Old South. Many very large and old specimens of live oak can be found today in the Deep South region of the United States.

<i>Quercus gambelii</i> Species of oak tree

Quercus gambelii, with the common name Gambel oak, is a deciduous small tree or large shrub that is widespread in the foothills and lower mountains of western North America. It is also regionally called scrub oak, oak brush, and white oak.

<i>Juniperus scopulorum</i> Western North American species of juniper

Juniperus scopulorum, the Rocky Mountain juniper, is a species of juniper native to western North America, from southwest Canada to the Great Plains of the United States and small areas of northern Mexico. They are the most widespread of all the New World junipers. They are relatively small trees, occasionally just a large bush or stunted snag. They tend to be found in isolated groves or even as single trees rather than as the dominant tree of a forest. Though they can survive fires, they are vulnerable to them especially when young and this is one of the factors that can limit their spread into grasslands.

<i>Calocedrus decurrens</i> Species of conifer

Calocedrus decurrens, with the common names incense cedar and California incense cedar, is a species of coniferous tree native to western North America. It is the most widely known species in the genus, and is often simply called incense cedar without the regional qualifier.

<i>Viscum album</i> Flowering plant in the mistletoe family Santalaceae

Viscum album is a species of mistletoe in the family Santalaceae, commonly known as European mistletoe, common mistletoe or simply as mistletoe. It is native to Europe and western and southern Asia.

<i>Phoradendron</i> Genus of mistletoes

Phoradendron is a genus of mistletoe, native to warm temperate and tropical regions of the Americas. The center of diversity is the Amazon rainforest. Phoradendron is the largest genus of mistletoe in the Americas, and possibly the largest genus of mistletoes in the world. Traditionally, the genus has been placed in the family Viscaceae, but recent genetic research acknowledged by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae.

<i>Loranthus</i> Genus of mistletoes

Loranthus is a genus of parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers. Other treatments restrict the genus to a few species. The systematic situation of Loranthus is not entirely clear.

<i>Phoradendron juniperinum</i> Species of flowering plant

Phoradendron juniperinum is a species of flowering plant in the sandalwood family known by the common name juniper mistletoe. It is native to the southwestern United States and northern Mexico, where it grows in various types of woodland habitat. It has been reported from California, Nevada, Arizona, New Mexico, Oregon, Utah, Texas, Chihuahua and Sonora.

Phoradendron libocedri is a species of flowering plant in the sandalwood family known by the common name incense-cedar mistletoe. It is native to western North America from Oregon to Baja California, where it grows in forests on its host tree, the California incense-cedar.

<i>Phoradendron macrophyllum</i> Species of flowering plant

Phoradendron macrophyllum is a species of flowering plant in the sandalwood family known by the common names Colorado Desert mistletoe, bigleaf mistletoe, and Christmas mistletoe. It is native to western United States and northern Mexico from Oregon to Colorado to Texas to Baja California, where it grows in many types of wooded habitat at elevations up to 1700 m.

<i>Phoradendron villosum</i> Species of mistletoe

Phoradendron villosum is a species of flowering plant in the sandalwood family known by the common names Pacific mistletoe and oak mistletoe. It is native to western North America from Oregon south into Mexico, where it grows in oak woodland and similar habitat.

<i>Phoradendron tomentosum</i> Species of mistletoe

Phoradendron tomentosum, the leafy mistletoe, hairy mistletoe or Christmas mistletoe, is a plant parasite. It is characterized by its larger leaves and smaller berries than dwarf mistletoe. Leafy mistletoe seldom kill but they do rob their hosts of moisture and some minerals, causing stress during drought and reducing crop productions on fruit and nut trees. Leafy mistletoe has the ability to photosynthesize on its own but it relies on other plants in order to obtain its nutrients. It attaches itself to a tree and then grows haustoria, in order to get the food and water it needs.

Phoradendron coryae, Cory's mistletoe or oak mistletoe, is a hemiparasitic plant native to the southwestern United States and northern Mexico. It is reported from Arizona, New Mexico, Texas, Chihuahua, Coahuila and Sonora.

Hairy mistletoe is a common name for several plants and may refer to:

<i>Phoradendron bolleanum</i> Species of flowering plant

Phoradendron bolleanum, commonly called Bollean mistletoe, is a species of plant in the sandalwood family that is native to the desert southwest, California and southern Oregon in the United States and Mexico.

Phoratoxins are a group of peptide toxins that belong to the family of thionins, a subdivision of small plant toxins. Phoratoxins are proteins present in the leaves and branches of the Phoradendron, commonly known as the American variant of the mistletoe, a plant commonly used as decoration during the festive season. The berries of the mistletoe do not contain phoratoxins, making them less toxic compared to other parts of the plant. The toxicity of the mistletoe is dependent on the host tree, since mistletoe is known to be a semi-parasite. The host tree provides fixed inorganic nitrogen compounds necessary for the mistletoe to synthesize phoratoxins.
