This strange plant is called the “dodder.” When it was still a baby plant, it lay within its seed upon the ground, just like other baby plants; and when it burst its seed shell, like other plants it sent its roots down into the earth.
But unlike any other plant I know of, it did not send up into the air any seed leaves. The dodder never bears a leaf.
It sent upward a slender golden stem. Soon the stem began to sweep slowly through the air in circles, as if searching for something. Its movements were like those of a blind man who is feeling with his hands for support. And this is just what the plant was doing: it was feeling for support. And it kept up its slow motion till it found the plant which was fitted to give it what it needed.
Having made this discovery, it put out a little root. This root it sent into the juicy stem of its new-found support. And thereafter, from its private store, the unfortunate plant which had been chosen as the dodder’s victim was obliged to give food and drink to its greedy visitor.
And now what does this dodder do, do you suppose? Perhaps you think that at least it has the grace to do a little something for a living, and that it makes its earth root supply it with part of its food.
Nothing of the sort. Once it finds itself firmly rooted in the stem of its victim, it begins to grow vigorously. With every few inches of its growth it sends new roots deep into this stem. And when it feels quite at home, and perfectly sure of its board, it begins to wither away below, where it is joined to its earth root. Soon it breaks off entirely from this, and draws every bit of its nourishment from the plant or plants in which it is rooted.
Now stop a moment and think of the almost wicked intelligence this plant has seemed to show,—how it keeps its hold of the earth till its stem has found the plant which will be compelled to feed it, and how it gives up all pretense of self-support, once it has captured its prey.
You have heard of men and women who do this sort of thing,—who shirk all trouble, and try to live on the work of others; and I fear you know some boys and girls who are not altogether unlike the dodder,—boys and girls who never take any pains if they can possibly help it, who try to have all of the fun and none of the work; but did you ever suppose you would come across a plant that would conduct itself in such a fashion?
Of course, when the dodder happens to fasten itself upon some wild plant, little harm is done. But unfortunately it is very partial to plants that are useful to men, and then we must look upon it as an enemy.
Linen is made from the flax plant, and this flax plant is one of the favorite victims of the dodder. Sometimes it will attack and starve to death whole fields of flax.
