LESSON CLVIII The Bee-larkspur Leading thoughtâThe bee-larkspur begins blossoming early in the season, the blossom stalk elongating and developing new buds at its tip until late in autumn. The flower has a very interesting way of making the bees carry its pollen. MethodâBring to the schoolroom a flower stalk of the bee-larkspur, and there study the structure and mechanism of the flower. This lesson should inspire the puoils to observe for them- selves the visiting bees and the maturing seeds. Ask them to write an account of a bumblebee making morning calls on the larkspurs. Observationsâi. Which flowers of the lark- spur open firstâthose near the tip of the stem or those below? 2. Examine the buds toward the tip of the flower stalk. What color are the sepals in these buds? Do the sepals change color as the flower opens? Note the little green knobs which tip the closed sepals that clasp the bud. What color are the sepals on the open flower? Is there any green upon them when open? 3. Where is the nectar-spur? Which sepal forms this? How are the other 4. Now that we know the flower gets its brilliant color from its sepals, let us find the petals. Look straight into the flower, and note what forms the contrasting color of the heart of the flower; these are the petals. Can you see that two are joined above the open- ing into the nectar-tube? How many guard the entrance from below? How are these lower petals hinged about the upper one? Peel a sepal- cover from the nectar-spur, and see if the upper petals extend back within the spur, forming nectar-tubes? 5. Take a flower just opened, and describe what you see below the petals. What is the color of the anther
