These come from plants that belong to the Pea family and are called Tick Trefoil. There are nearly two dozen kinds of them, and sometimes they seem to be everywhere in the woods and thickets.
The pods are like pea pods, only that they are jointed, and the joints break apart, so that each may be carried away separately. Each joint contains a little pealike seed.
The outside of the pod seems fuzzy, and it clings very closely to whatever it touches. If we look at the fuzz with a magnifying glass, we shall find it made up of innumerable little hooks.
The hairs that cover the pod are turned up at the end to form little hooks, very delicate, but able, when there are so many of them, to hold on very tightly.
They seem to snuggle down into the cloth they touch, so that it is difficult to pick them off, and the joints all separate when we try to remove them, so that each one has to be taken off separately.
Another plant whose seed pods are covered with hooked hairs is the sweet-scented bedstraw. This is a pretty little plant that spreads about on the ground. Its flowers are small and greenish, but the whole plant when in bloom has a pretty lace-like effect as we find it in the woods very often growing about fallen logs.
Sweet-scented bedstraw.
Its seed pods are small and, like the tick trefoil, are covered with hairs that, under the magnifying glass, are seen to be hooked.
The enchanter’s nightshade is another little plant whose seed pods are covered with hooked hair. It is as pretty as its name and is to be found in damp woods.
