HISTORY AND EVOLUTION 15 



the apical notch. Then came the hooded 

 form, in which the edges of the standards 

 are rolled forward. There are various de- 

 grees of hooding in different varieties. 

 Extreme hoodings were at one time recog- 

 nized under the name of snapdragon va- 

 rieties, which were never more than a pass- 

 ing novelty. Finally, there is the waved 

 form in which the edges of the standards 

 and often the wings are beautifully 

 waved. This is the most handsome form 

 of sweet pea flower (the flowers are larger 

 and have longer stems) , and it is probable 

 that the other forms will pass away. The 

 older types, however, seed more freely, and 

 therefore it has been possible to produce 

 seed more cheaply. However, any one 

 who has grown the waved or Spencer va- 

 rieties will not again take up the culture of 

 the old varieties, and therefore in the 

 course of time the latter are doomed.
