are the same as in the single. As long as the petaloids are all 

 tipped with vestiges of anthers, the flower is to be regarded as of 

 the Japanese type. An example is " Glory." (See Fig. 19.) 



Bomb. — • After the next step toward doubling has been taken, 

 we have the bomb. In this the petaloids have become still widfer 

 and more thickly set, due to chorisis of the cords. 



No vestige of anthers must show here, however, and the 

 petaloids, while approaching the guard petals in form, must still be 

 very distinctly differentiated from them. The seed vessels must 

 also be well concealed by the petaloids. I regard Chas. Binder 

 (Fig. 20) as a good example of this class. 



Semi-double. — This class is formed to accommodate certain 

 varieties which, instead of widening their filaments uniformly until 

 a petaloid is formed, produce petaloids in all stages of transforma- 

 tion at the same time. They are usually loose in structure and are 

 especially common in dark red kinds. The guard petals may or 

 may not be well differentiated in this class, which will probably 

 resolve itself in time into a sort of miscellaneous group into which 

 may be put doubtful forms, or forms which will go nowhere else. 



LxDuis Van Houtte (Fig. 21) is a good example of this type, as 

 is also the peony used to illustrate evolution of petals from stamens 



(Fig. 17). 

 Crown. — • It often happens that the carpels will be either partly) 



or fully transformed into petaloids which differ from both the 



guard petals and the petaloids which have been derived from the 



stamens. This type of flower we call the crown, and in case the 



carpels are not transformed but are more conspicuous on account 



of the reflexing of the other petaloids, they are also placed in thd 



crown class, but called reflexed crowns. Fig. 22. (Princess Beatrice) 



illustrates the typical crown, and Fig. 23 ( Whitley i) the reflexed 



crown. Figure 23 is not quite typical of this variety, as the bloom 



came from a young plant, and carpelody has not gone as far as 



usual. 



Rose. — The rose is the common type of the fully double bloom. 

 In it all the stamens and carpels are fully transformed into more 

 or less evenly arranged petaloids. They may not in every case be 

 indistinguishable from the guard petals, but when the guards are 

 quite distinct it would be called a bomb. The line dividing the rose 

 and the bomb is thus seen to be quite an arbitrary one. 



Festiva Maxima and Avalanche are very good illustrations of 

 what is meant by the rose type.
