THE AMERICAN BOTANIST 9 



2. The test of fragrance lies, not in one flower, but in a 

 mass. This is more particularly true of small flowers. 



3. Very commonly, flowers of the same species grow- 

 ing in shade, are not so fragrant as those growing in open sun- 

 light. 



4. Most flowers seem to lose fragrance when plucked 

 and withering, but a few species appear to be more fragrant 

 under this condition. 



5. The fragrance of some flowers is worth noting, even 

 if it is only slight, because of quality or peculiarity.
