Plant anatomy; Botany; Botanique; Botanique. RLEMENTS OF STRTTCTURAL Fip. G. 1) w linwevor, oxnininc tlicsc parts that re- niaiu. Tlierc is first a lar<;e number of little yellow bodies, each at the top of a little thread-like stalk. Each of these bodies, with its stnlk, is called a stamr The little body itself is the antlnr, and the stalk is its tildiiii'nt. Your inaf]jnifyinf» glass will show you that each anther consists of two oblon<,' sacs, united len^^^th- wise, the filament being a continuntion of the line of union. (Fig. 7.) If you look at a stamen of a iiower which ; has been open some time, you will find that lach 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 pollrn. A powerful Fig 8 magnifier will sliow 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 jmlidiKhwis. \ 7. On removing the stamens there is still left a little raised mass, (Fig. J)) which with the aid of your needle you will be able to separate into a number of distinct pieces, all exactly alike, and looking something like unripe seeds. Fig. 10 shows one of them very much magnified, and cut through lengthwise. These little bodies, taken separately, are called car/tds. Taken together, they form the pistil. They are hollow, and each of them contains, as the figure shows, a little grain-like substance attaclied to the lower end of its cavity. This substance, in its present condition, is the ovule, and later on becomes the seed. Fir. 7. Fig. 9.
