Host Range
Some parasitic plants are generalists and parasitize many different species, even several different species at once. Dodder (Cassytha spp., Cuscuta spp.) and red rattle (Odontites verna) are generalist parasites. Other parasitic plants are specialists that parasitize a few or even just one species. Beech drops (Epifagus virginiana) is a root holoparasite only on American beech (Fagus grandifolia). Rafflesia is a holoparasite on the vine Tetrastigma.

Famous quotes containing the words host and/or range:
“Nothing is quite so wretchedly corrupt as an aristocracy which has lost its power but kept its wealth and which still has endless leisure to devote to nothing but banal enjoyments. All its great thoughts and passionate energy are things of the past, and nothing but a host of petty, gnawing vices now cling to it like worms to a corpse.”
—Alexis de Tocqueville (1805–1859)
“The Canadians of those days, at least, possessed a roving spirit of adventure which carried them further, in exposure to hardship and danger, than ever the New England colonist went, and led them, though not to clear and colonize the wilderness, yet to range over it as coureurs de bois, or runners of the woods, or, as Hontan prefers to call them, coureurs de risques, runners of risks; to say nothing of their enterprising priesthood.”
—Henry David Thoreau (1817–1862)
