Field Notes

Description:

Mistletoe in a stand of Bradford pear trees. Semi-parasitic. Berry pulp remains sticky as it passes through birds' digestive tracts. When the seed is excreted, the pulp makes it stick to the branch it lands on, and it sprouts there. Phoradendron is derived from the Greek for "tree thief."

Notes:

Phoradendron leucarpum also called Phoradendron serotinum<br><br>

From Wikipedia:<br><br>

Phoradendron leucarpum is a species of mistletoe which is native to the United States and Mexico. Its common names include American mistletoe, eastern mistletoe, hairy mistletoe, oak mistletoe, Pacific mistletoe, or western mistletoe.<br><br>

They are woody hemi-parasitic shrubs with branches 10–80 cm (3.9–31 in) long, which grow on other trees. The foliage is dichotomously branching, with opposite pairs of leaves; these are fairly large, 2–5 cm (0.79–2.0 in) long, green and photosynthetic in some species (e.g. P. leucarpum), but minimal in some others (e.g. P. californicum).<br><br>

Although they are able to photosynthesize the plant relies of its host for some nutrients. The plant draws its mineral and water needs, and some of its energy needs, from the host tree using a haustorium which grows into the stems of the host. The genus name Phoradendron is derived from the Greek for "tree thief".<br><br>

The flowers are inconspicuous, greenish-yellow, 1–3 mm (0.039–0.12 in) diameter. The fruit is a berry, white, yellow, orange, or red when mature, containing several seeds embedded in very sticky juice. The seeds are dispersed when birds eat the fruit and remove the sticky seeds from their bills by wiping them on tree branches where they can germinate.<br><br>

The foliage and berries of some species are toxic. Leafy mistletoes seldom kill but they cause stress during and reducing crop productions in fruits and nut trees.
