EI.EMENTS OF STRTTCTURAL BOTANY.

however, examine these parts that re- 

 main. There is first a large number of 

 Httle yellow bodies, each at the top of a 

 little threatl-like stalk. Each of these 

 bodies, with its stalk, is called a stamen. 

 The little body itself is the anther, and the stalk is its 

 fdament. 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.) 



If you look at a stamen of a flower which 

 j-; has been open some time, you will find that 

 each 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 pal leu. A powerful 

 Fis- 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 pol'/aiulrous. 



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 alike, and 

 looking something hke unripe seeds. Fig. 10 

 shows one of them very much magnified, and cut 

 through lengthwise. These little bodies, taken 

 separately, are called varpds. Taken together, 

 they form the pistil. They 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 seed.
