This is the commonest of our Dodders, and is found in twisted and tangled masses about herbs and low shrubs, during July and August, from Canada to the Gulf States. It is a variable species and is known as a parasite. Its seeds germinate annually in the soil and the plantlet promptly attaches itself to the nearest favourable growth which becomes its host. Its roots and lower portion soon perish, and the vine then depends upon its numerous, minute suckers to absorb its nourishment from the host to which it is attached. It is a slender, high climbing, leafless, thread-like vine, varying in colour from yellow to orange, and producing numerous, dense clusters of tiny, dull white flowers. The little corolla is broadly bell-shaped with five rounded, spreading lobes containing five fringed scales, above which are inserted the five stamens. The minute calyx is greenish white. This Dodder is found chiefly in moist, shaded soil in low thickets and near streams.
