Lesson CXXIV

The Mandrake

Leading thought—These interesting plants grow in colonies because of the spreading of their underground stems. Their odor and poisonous qualities protect them from being eaten by animals, and their fruit is well hidden by its green parasol until it is ripe.

Method—Begin the study just as the mandrakes are thrusting their heads up through the soil in April, and continue the work at intervals until the fruit is ripe.

Observations—1. How do the mandrakes look when they first appear above the ground? How are the little umbrellas folded in their cases? What do the cases look like? How can you tell from the first, the plants which are to bear the flowers and fruit?

2. Study a patch of mandrakes, and see how many varieties of parasols you can find? Do they all have the same number of main ribs and lobes? How many lobes do most of them have? Are there more single or double parasols in the patch?

3. Take a single plant and study it carefully. What sort of stem has it? Can you find at its base the old umbrella case? How high is the stem? What is its color at the bottom and at the top? How many ribs does it divide into at the top? Are these ribs as smooth as the stem? How does the parasol lining differ from its outside in color and feeling?

4. Study the parasol lobes. What is their general shape? Are they all notched at the wide end? How close to the stem does the division between them extend? Do you not think they are better fitted for keeping off the sun than the rain?

5. Take one of the double parasols. Where is the flower bud to be found? How is it protected from the sun? Does the stem divide equally on each side of it or is one part larger than the other? Are the twin parasols of the same size? How many lobes has each? What are the chief differences in shape between one of these twin parasols and one of the parasols which has no flower bud?

6. How does the flower bud look? Does it droop because its stem is weak? What happens to the green hood or sepals when the flower opens? Can you find six sepals in the hood?

7. Does the open flower bow downward? As the flower opens, what is the shape of the group of stamens at the center? Are there the same number of white, waxy petals in all the flowers? Are there always about twice as many stamens as petals? How do the anthers open to shed the pollen? Do they let the pollen fall away from the ruffled stigma of the “fat” little seed box at the center of the flower?

8. Does the flower have a strong odor? Does not the plant itself give off this odor? Do you think it is pleasant? Do the cattle eat the mandrake when it is in pastures?

9. What insects do you find visiting the mandrake flowers?

10. Do you like the May apple? When is it ripe? Cut a fruit across and see how the seeds are arranged.

11. Where are mandrakes found? Do they always grow in patches? Dig up a few plants and find why this is so?

12. Describe the underground stem. Can you find where the last year’s plant grew? How are the roots arranged upon the stem? Can you see places which will produce the stem for next year’s growth? How does the underground stem differ in appearance from the true roots? Why must we not taste of the mandrake root?

13. In late July, visit the mandrake patch again. Are there any umbrellas now? What is left of the plants? Look at the underground stems again and see if there are new growths, and if they are larger and stored with food for next year’s plants.
