DODDER (Frisian See also:dodd, a bunch; Dutch dot, ravelled See also:thread)  , the popular name of the See also:annual, leafless, See also:twining, parasitic See also:plants forming the genus Cuscuta, formerly regarded as representing a distinct natural See also:order Cuscutaceae, but now generally ranked as a tribe of the natural order See also:Convolvulaceae . The genus contains nearly See also:loo See also:species and is widely distributed in the temperate and warmer parts of the See also:earth . The slender See also:thread-like See also:stem is See also:white, yellow, or red in See also:colour, bears no leaves, and attaches itself by suckers to the stem or leaves of some other plant See also:round which it twines and from which it derives its nourishment . It bears clusters of small See also:flowers with a four- or five-toothed calyx, a See also:cup-shaped corolla with four or five stamens inserted on its See also:tube, and sometimes a See also:ring of scales below the stamens; the two-celled ovary becomes when ripe a See also:capsule splitting by a ring just above the See also:base . The seeds are angular and contain a thread-like spirally coiled embryo which bears no cotyledons . On coming in contact with the living stem of some other plant the seedling See also:dodder throws out a sucker, by which it attaches itself and begins to absorb the See also:sap of its See also:foster-See also:parent; it then soon ceases to have any connexion with the ground . As it grows, it throws out fresh suckers, establishing itself firmly on the See also:host-plant, (fig . 2) . After making a few turns round one stem the dodder finds its way to another, and thus it continues twining and branching till it resembles " See also:fine, closely-tangled, wet See also:cat-gut." The injury done to See also:flax, See also:clover, See also:hop and See also:bean crops by species of dodder is often very See also:great .. C. europaea, the greater dodder (fig . 1) is found parasitic on nettles, thistles, vetches and the hop; C . Epilinum, on flax; C .

Epithymum, on See also:

furze, lingand See also:thyme . C . Trifolii, the Clover Dodder, is perhaps a sub-species of the last mentioned .
