 given a sliglit indication of a floral character, is transformed into a leafy branch, 

 shomng that all parts of the flower are formed out of the same elements as the 

 leaves. 



h. Sometimes the flower-stalk is not effectually checked in its growth by the 

 development of the flo■^^■er, but is prolonged through it, and produces secondary 

 flowers in the midst of tlie organs of the first. This is not unfrequent in the rose. 

 Several instances of these malformations are exhibited below. (Fig. 6.) 



k. This mode of studying the floral stnicture is deeply interesting and insti-uc 

 tive, but our limits wll not pennit us to dwell upon it, nor is it necessary. The 

 intelligent student will be able to extend the above illustrations by an examina 

 tion of almost any flower, with refei'ence to its deviations from th§ nonnal plan. 



FIG. 6. — 1, From Lindley, — a flower of white clover, reverting to a leafy branch ; 2, he 

 drawn from a living specimen, — a tulip, 6, a leaf arising from the peduncle, takes the pos 

 tion, form, and color (in part) of a sepal ; 3, here drawn from a living specimen, — a rose (R. 

 damascena) with the axis prolonged into secondary rose-buds. 



j^*j^ In our detailed description of the flower, we shaU commence with those 

 organs which are deemed essential, their mysterious agency being indispensable to 

 the perfection of the seed.
