Description

The genus Cuscuta contains quite a number of species which go under the common name of dodder, and which have the peculiarily of living as parasites upon other plants. Their habits are unfortunately too well known to cultivators, who justly dread their incursions among cultivated plants like flax, hops, etc. All parasitic plants, or at least the majority of them, have one character in common which distinguishes them at first sight. In many cases green matter is wanting in their tissues or is hidden by a livid tint that strikes the observer. Such are the Orobanchaccæ, or "broomropes", and the tropical Balanophoraceæ. Nevertheless, other parasites, such as the mistletoe, have perfectly green leaves.
