composed of four sepals, four petals, four stamens and four 

 carpels, was in the process of formation. Such flowers have 

 later been obtained and a truly new type of violet realized. 



A detailed description of the normal violet flower together 

 with a brief description of the complete and incomplete peloric 

 forms and their correlation with other characters will now be 

 given . 



Description of the Normal Violet Flower 



The normal violet flower is too well known to warrant a de- 

 tailed description. However, for the sake of comparison with 

 those of .the peloric types, the essential characters will be briefly 

 mentioned. 



The calyx is composed of five sepals, three of which are plainly 

 auricled. The corolla is composed of one saccate or spur bearing 

 petal, which normally is situated at the base of the flower, and 

 four others which are non-saccate. In addition to the saccate 

 character, this petal is easily distinguished by its long and dis- 

 tinct, dark purplish inner striations. The androecium is com- 

 posed of five stamens each of which bears a pair of anther-sacs. 

 Onl}^ two stamens of the set of five bear a stamen-appendage. 

 They are located one on each side of the saccate petal and the 

 two appendages are enclosed in the one sac. The pistil is com- 

 posed of three carpels with as many placentae to which the 

 ovules are attached. The style has a decided dorso-ventral 

 curvature immediately above the ovary and its gradual upward 

 dilation ultimately forms the stigma. The pore-tube slants 

 at a decidedly sharp angle with the longitudinal axis of the style. 



These are the characters of the normal flower of Viola primu- 

 laefolia Linn, and are enumerated at this time merely for the 

 sake of a contrast with similar ones found in the various peloric 

 forms.

 their Correlations 



In view of the fact that two wonderful changes are taking 

 place in the flowers of this violet plant, it might be well to repeat
