Higher plants cause injuries and diseases of other higher plants by shading, strangling, and parasitizing the others. Epiphytes, such as Spanish moss and other bromeliads, shade their living supports whereas grape vines and bittersweet strangle as well as shade theirs. Some, such as the mistletoes and dodders, are true parasites (Figs. 54-1,-2). The dodders are of special interest as vectors of viruses as well as obligate parasites and are useful in experimental transmission of viruses.
