Taxonomic notes
The name "mistletoe" comes from the ancient Anglo-Saxon word for dung and twig, which is derived from the observation that mistletoe often sprouts out of bird dropping on branches[1].
Description
P. leucarpum is a clumpy, evergreen shrub that can be found growing on branches of broad-leaved trees. The leaves are opposite, thick and leathery, oval to round. Flowers are small and inconspicuous and the fruits are white[1].
It is a hemiparasitic species that has chlorophyll and produces it's own food, but also has modified roots that extracts water and minerals from the host tree's circulatory system[1]. It infects more than 105 tree species: broadleaf, evergreen, deciduous, and confiers[2].
Distribution
P. leucarpum can be found on hardwood trees in the eastern United States[1].
Ecology
Habitat
Phoradendron leucarpum can be found in mixed hardwoods, cypress swamps, tupelo swamps, floodplain forests, and pine/oak scrubs. It is a parasitic plant that has been observed growing on Fraxinus, Liquidambar, Quercus nigra, Carya glabra, Prunus umbellata, Prunus angustifolia, Celtis laevigata, Quercus myrtifolia, Prunus serotina, Planera aquatica, Carya aquatica, Quercus virginiana, Acer, Morus, Populus, Ulmus and Magnolia (FSU Herbarium).
Phenology
It has been observed fruiting January, March, November and December; and flowering January, October, and December (FSU Herbarium). The ripe fruit is a transluscent, pseudo-berry, that contains viscin, which allows the seed to attach to bark[2].
Seed dispersal
The seeds are primarily dispersed by birds in excrement and regurgitation[2].
Seed bank and germination
This species does not exhibit strong seed dormancy. The translucent fruit skin must be pierced or removed to allow for seed germination[2].
Fire ecology
It has been observed in recently burned pine forests (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Phoradendron leucarpum at Archbold Biological Station (Deyrup 2015):
Vespidae: Mischocyttarus cubensis
Use by animals
The fruit is eaten by birds. This plant is poisonous to humans [1].
