Cucumber: Pollen BEARING Flower cells for each style and stigma. You should see the in- teresting nectar cup on the top of the ovary, on which glistening drops of nectar may generally be found. Squash Blossoms People are sometimes puzzled over the fact that cucum- bers and squashes seem to have so many blossoms in pro- portion to the number of fruits produced. If you examine, however, the flowers upon one of these plants, you will soon be able to tell the reason for this. You will find that most of the flowers consist only of sepals, petals, and stamens, and that such flowers are easily recognized from a side view, by the fact that there is below the blossom no little cucumber or squash to develop later into a fruit. These flowers are stamen-bearing orstam- inate blossoms, and in general they are smaller than the other kind of flowers found upon the same plants, which con- sist of sepals, petals, and a single pistil. The ovary of the pistil which you will recognize at once as a miniature cu- cumber or squash is below the main blossom, but has a style that runs up through the center of the flower and bears upon its tip a well-developed stigma. These are the seed-bearing or pistillate flowers. If you should cut open the ovary of one of these pistillate flowers, you would find inside a large number of tiny seed- Uke bodies called the ovules. In order that these ovules may develop into seeds, it is necessary that some pollen from the staminate blossoms should be placed upon the.
