104 THE AMERICAN BOTANIST 



Much of the beauty of our flower gardens is clue to the 

 variations in color which these flowers present. A few flowers 

 of more than one color may appear regularly in nature, as in 

 the case of hepatica and the painted-cup, but usually the vari- 

 ations first appeared as sports and have since been continued 

 artificially. A partial list of species with this peculiarity is 

 given on another page, but it is likely that it can be greatly 

 extended and records to that end are invited. In considering 

 the matter, changes of color in a singie species only should 

 be reported since, as we have indicated, the different species 

 of a genus may be differently colored. 



Closely connected with variations in color is the habit 

 some plants have of changing color as the blooming season 

 progresses. The most familiar of such changes is the pink 

 color that often appears as the flower begins to wane, but a 

 large number of other changes may be noted by an attentive 

 observer. Some of the more conspicuous are listed here, but 

 other records are desired. 



As a general rule, flowers tend to be of a single color or, 

 when more than one color is present, the others occur as lines, 

 dots and blotches. There are a number of species, however, 

 that have two distinct areas of color. Some of these are also 

 listed. As for the albinos, although the casual observer may 

 be inclined to consider them worthy of a separate name and 

 describe them in sounding Latin terms, they are really to be 

 expected in the cyanic group of flowers, as we have indicated, 

 and at some future date we intend to make a list of them. 

 Quite analogous to such forms are pink forms of typically blue 

 flowers, yellow forms of typically red forms, and red forms 

 of typically yellow flowers. All such are worth listing.
