CHAP, xvni A TYPICAL OR PATTERN FLOWER 83 



II. Remove several stamens entire, examine one a little 

 more carefully under the lens and notice : 



1 . The size, shape, and color of the filaments. 



2. The way in which the anther is attached to the filament. 



3. Examining the anthers in some buds or flowers not yet 



opened, notice the two longitudinal halves of each 

 anther each is called an anther cell. 



4. Examining the stamen of an older flower, notice how 



each anther cell opens to allow the pollen to escape. 



5. Make sketches to show this. 



III. Remove several pistils carefully and examine the 

 different parts under the lens (or better, under a dissecting 

 microscope) . Notice : 



1. The stigma, its size, shape, and structure. (Compare if 



possible the stigma of the pistil of a Lily or Begonia 

 and notice the roughness and moistness of the stigma. 

 Touch such a stigma to the tongue and notice its 

 taste. Sometimes the stigma of the Lily has enough 

 moisture upon it to form a distinct drop.) 



2. The slender style, its smoothness as compared with the 



stigma. 



3. The swollen ovary. Carefully cut the ovary longitudi- 



nally along one edge and open it. Within will be 

 found 



4. A hollow, the cell of the ovary within the cell may be 



seen 



5. A row of small bodies, the ovules. These are the bodies 



which ripen into seeds. 



6. The surface to which the ovules are attached is called 



the placenta. This pistil has only one placenta. 



7. Make a sketch (or diagram) to show these points, and 



label carefully.
