- Depending on the particular species, dodder vines range from very slender forms as fine as human hair to coarse ones a few millimetres in diameter.
- During all this growth dodder obtains its nourishment from the host through numerous absorptive organs called haustoria which develop all along the coiled regions of the vine on the inner surface in contact with the host.
- The dodder's ability to lead a parasitic life thus depends on its ability to develop haustoria, an evolutionary adaptation which in one stroke has rendered redundant the need for two major organs; the roots for supplying water and minerals and the green leaf for preparing food through photosynthesis.
- The Index Kewensis lists more than 250 species of dodder and while some of these are possibly synonyms of the same species collected from different localities, the dodder appear to be native to all the large temperate and tropical land masses of the world.
- The word is apparently derived from the Germanic dotter or yolk of egg, which is roughly the colour of the common European dodder, and is now used as a common name for all species belonging to the genus Cuscuta .
- The dodder is one of nature's most accomplished parasites.
- An Arabic poet compares purposeless human qualities with kushooth - a dodder species from which the Latin Cuscuta is possibly derived - with the line: "He is like the kushooth; for he has neither root, leaves, fragrance, shade of fluit".
- In more recent times dodder vines have been used as "bridges" to transmit certain types of viruses from one host plant to another, so rapidly spreading the infections.
- Erasmus Darwin, grandfather of Charles, describes dodders in verse as "harlot-nymphs" which crush their prey in their coils much as the mythological serpents crushed Laocoon and his sons, while Indian myths grant unlimited wealth and the power of invisibility to those who find the roots of dodder.
- THE DICTIONARY describes dodder as a non-green, leafless, rootless, twining flowering plant, that parasitises other plants for its nutrients and water.
- The vegetative part of the dodder plant is an epiphyte (that is, a plant that grows on other plants) consisting exclusively of thread-like, often yellowish vines partly coiled around the stem of its host and partly draped over it or hanging free.
- The dodder has no leaves and no connection with the soil after its seeds have germinated; the roots do not develop.
