Available in PDF, EPUB and Kindle. Book excerpt: Mistletoes are a fascinating group of parasitic flowering plants that occur throughout most of the World. In mainland North America north of Mexico, there are only two native mistletoe groups: the dwarf mistletoes and the leafy mistletoes. The dwarf mistletoes are widespread, common parasites of coniferous trees. They are considered among the most important forest tree diseases in North America. Although, the leafy mistletoes are also widespread, they are not as damaging to their hosts. Throughout human history, mistletoes have played an importantrole in mythology, Christmas traditions, and as a part of the medicinal arsenal with which to fight disease. Mistletoes also have important relationships with many other living organisms. They provide valuable food sources and habitat for birds, mammals, insects, and fungi. Leafy mistletoes are dependent on birds like the phainopepla illustrated here, for seed dispersal.This book covers all the dwarf and leafy mistletoes recognized by the author that are found in the continental United States and Canada. General descriptions, geographic distributions, and lists of hosts for each mistletoe are provided. In addition, distribution maps illustrate where each mistletoe is found, and photos help acquaint readers with their general appearance and habit. Supplemental materials include: a table listing principal and less commonly infected hosts of each species of dwarf mistletoe that can be used as a short cut for their identification; dichotomous keys to assist in identification for those who enjoy this form of discovery; and sidebars covering a range of interesting topics related to the biology, classification, ecology, and cultural significance of mistletoes expands this user-friendly guide.
