All these stems are usually called roots. In the botanies such an underground stem as that of the Jack-in-the-pulpit (Fig. [114]) is named a “corm,” while one like that of the crocus is called a “bulb” (Fig. [112]). All have a somewhat rounded shape.

During our walks in the woods last fall, often we found the Solomon’s seal, and stopped to admire its curved stem, hung with blue berries. I hope one of you boys whipped out your pocketknife and dug into the earth till you found its underground stem (Fig. [115]). This was laid lengthwise, its roots growing from its lower side. From its upper side, close to one end, sprang the growing plant. But what causes those round, curious-looking scars?
These scars are what give the plant its name of “Solomon’s seal.” They are supposed to look like the mark left by a seal upon wax.
They show where the underground stem has budded in past years, sending up plants which in turn withered away. Each plant has left a scar which shows one year in the life of the underground stem.
