folds, and fall wfth it. The 2-celled anther is adnate (fixed 

 laterally) to the filament above. Opening lengthwise, the 

 cells disclose innumerable round, white grains of pollen, 

 which, under the mi- 

 croscope, appear beset 

 all over with blunt 

 points or tubercles. 



The style the central 

 organ smooth, slender, 

 supports the 3-lobed stig- 

 ma at the top, and stands 

 upon the free ovary. The 

 disk* a fleshy ring, be- 

 girts the ovary at its base; 

 hence it is annular and 

 hypogynous. The contents of the ovary will be understood 

 by viewing its various sections (cuttings) under a lens, when 

 3 cells, each with 2 ovules (young seeds) will be seen. Let 

 the student observe the attitude of the ovules, the place and 

 the organ whence they arise. Their destiny we well know. 

 They will become the seeds in the ripening fruit, and from 

 them new plants will arise the following year. 



The pollen. Watch the expanded flower at sunrise. 

 The anther cells are also open, and the pollen is set free, to 

 fall, to fly with the wind, or be rudely brushed away by the 

 humble-bee as he plunges into flower after flower in search 

 of the nectar secreted in its depths. Thus a thousand grains 

 may be lost, but some few are almost certain to be lodged 

 on the stigma standing in the midst. On this event depends 



* A disk is an outgrowth of the torus under or around the ovary. It may be 

 annular, or cup-form, according to the degree of its development. When it does not 

 adhere to the ovary or calyx, it is said to be free and hypogynous ; when it adheres to 

 the base of the calyx it is perigynous. Sometimes it adheres to both the calyx and 

 the ovary, gluing them together, and even enlarging on the top of the ovary, as in 

 the Umbelliferae ; then it is epigynous.
