. First studies in plant life in Australasia, with numerous questions, directions for outdoor work, and drawing and composition exercises. Botany. THE FLOWER 99.

The other three larger petals overlap a good deal; the two smaller do not overlap much, but, in the fully opened flower, are set almost edge to edge. 8. The honey-tube. Pull off now all the sepals except the largest, and all the petals. Take then your lens and see what lies hid at the base of the largest sepal. You see a hole leading down into the stalklet. Probe it with a pin, and you find that it goes down a long way. Here then is a tube. And now squeeze the tube gently between finger and thumb, and you will see that a fluid rises to the mouth of the tube. Put this to your tongue. It is sweet! We have found the honey-store! Also, we have found out the meaning of the ridge on the stem that made it look like a double stem. The ridge is the honey-tube (fig 71a). 9. The path to the honey. And now take another full flower, and see how the insect reaches this honey. The insect will alight on the largest of the petals. This large petal makes a kind of front step, and is strong enough with the help of the two other large petals to bear a large insect's weight. The insect will then push its head down the little opening at the base of the two smallest petals. As these petals meet only edge to edge, they will easily open to make room for the head of the insect. Now the largest sepal is always at the back of these two smallest petals ; and.
