2 1 8 DAFFODILS NARCISSUS 



divided into the (A), large-- ; (AA), me- 

 dium- ; and (AAA), small-crowned groups, 

 which are better distinguished commonly as 

 trumpets, cups and saucers. Under A, notice 

 that we have B, BB, and BBB, which show 

 that the petals spread horizontally in the first 

 species * point backwards in species Nos. 5 

 and 6 and forward in No. 7. 



In like manner, the most important dis- 

 tinctions among the medium-crowned daffo- 

 dils are indicated by B and BB under AA; 

 namely, that the leaves are broad and flat 

 in species 8 to 15 inclusive, while they are 

 narrow and rush-like in species 16 and 17. 



Again, among the small-crowned daffodils, 

 the most important distinctions are shown 

 by B, BB, and BBB, which clearly indicate 

 the number of flowers on a stem possessed by 

 species Nos. 18 to 28. 



Suppose now that we wish to place an un- 

 known flower in its proper section. We 

 choose first between A, A A, and AAA. If 

 our specimen has a large-crowned flower, it 



* (NOTE: For the present purposes the typical hybrid 

 groups, or sections, are regarded as species, and the peri- 

 anth segments are referred to simply as "petals").
