verticUs. The same thing is met with in the case of the other whorls, 

 and is well illustrated in the formation of the disk (p. 234). Multi- 

 plication causes a repetition of successive whorls, which still follow 

 the law of alternation. 



Parts of the flower are often increased by a process of deduplication, 

 unlining, dilammation, or clwrization, i.e. the separation of a lamina 

 from organs already formed (p. 210). This is believed to take place 

 in a remarkable degree in the case of appendages to petals. Thus, in 

 Eanimculus, the petal (fig. 655) has a scale at its base, a, which is 

 looked upon as .a mere fold of it. This fold may in some cases be 

 more highly developed, as in Oaryophyllacese, and in Crassula rubehs 

 (fig. 282 a), and it may even assume the characters of a stamen, 

 which will therefore be opposite the petal, as iu Primulacese. Some 

 do not consider the production of scales or stamens opposite to the 

 petals as the result of chorization. Lindley argues against it from 

 what is observed in CameUia japonica, in which the petals are usually 

 alternate; but, by cultivation, the law of alternation is interfered 

 with, and the parts are so developed that the petals are opposite, and
