14 DAFFODILS NARCISSUS 



Narcissus popticus, N. Tazetta and N. Jon' 

 quilla. 



The relationship of the flowers can be best 

 realized by looking at the diagrams in Plate 

 IV. It will be seen that there is a con- 

 siderable difference between the exterior 

 form of the flowers as well as in their in- 

 terior structure. From stem to mouth the 

 flowers are practically of the same length, 

 but the whorl of so-called petals* perianth 

 segments is placed near the mouth in typi- 

 cal "narcissus" flowers so that there is only 

 a shallow cup in front of it. In typical 

 "daffodils" the whorl is placed near the base, 

 allowing a longer portion called the "trum- 

 pet" in front. 



There are also differences of interior struc- 

 ture. In the narcissus proper the stamens are 

 in two series of three each, one set being con- 

 nected to the tube near the top, the other 

 lower down; in daffodils proper the stamens 

 are in one series of six all connected with 

 the tube at one point nearly at its base. Prac- 



*The term petals is used throughout this book to sig- 

 nify the perianth segments; it is more convenient and is 

 easily understood.
