There is first a large number of Uttle yellow bodies, each at the top of a little thread-like stalk. Each of these bodies, with its stalk, is called a stamen. The little body itself is the ant Iter, and the stalk is its filament. Your magnifying glass will show you that each anther consists of two oblong sacs, united length- wise, the filament being a continuation of the line of union. (Fig. 7.) /|\ 4T\,. If you look at a stamen of a flower which ( J 11)' ^^^^ ^^^" o\>Qn some time, you will find that ^ Y t;^ch anther-cell has split open along its outer edge, and has thus allowed a fine yellowish dust to escape from it. (Fig. 8.) This dust IS called pollen. A powerful Fir. 7. Fig 8 magnifier will show this pollen to consist of grains having a distinct form. As the stamens are many in number, and free from each other, they are said to be poh/omhous. 7. On removing the stamens there is still left, a little raised mass, (Fig. 9) which with the aid of your needle you will be able to separate into a number of distinct pieces, all exactly aUke, and looking something like unripe seeds. Fig. 10 shows one of them very much magnified, and cut through lengthwise. These httle bodies, taken separately, are called carj)els. Taken together, they form the pistil. T^ey are hollow, and each of them contains, as the figure shows, a little grain-like substance attached to the lower end of its cavity. This substance, in its present condition, is the ovule, and later on becomes the need. Fig. 9.
