ingly exists between the character and position of some of the 

 constituent parts of one floral whorl and those of other whorls 

 within the same flower. F'or instance, the saccate petal usually 

 is. correlated with an appendage al^xed to one of the adjacent 

 stamens; and the size of the sac seems correlated with the size 

 and development of the enclosed appendages. Apparently an 

 exception to this rule is found within the extreme peloric flowers 

 where one saccate petal is regularly seemingly unaccompanied 

 by the usually inclosed stamen appendage. 



Another correlation that might be mentioned is one existing 

 between the number of stamen appendages and the type of 

 stamen ; for instance, the twin appendages are always associated 

 with the triple anther-sac stamen but these in turn need not 

 always bear the twin appendages. 



Inheritance of Peloria and the Tendency toward 

 Numerical Uniformity in the Floral Whorls 

 in Viola primulaefolia 



As soon as the plant bearing peloric flowers was discovered it 

 was transplanted to a more suitable field where it continued to 

 grow and develop seed. Some of the seeds were saved and 

 planted in a flat where they germinated early in 1913. Sixteen 

 plants were secured and later transplanted to an open field 

 where they bloomed the following year. All of these plants 

 produced flowers similar to those of the parent plant. The 

 sixteen plants soon began to multiply by means of stolons and 

 soon a patch or a solid mat of plants was formed. All of the 

 plants originating from stolons also produced flowers quite 

 similar to those of the parent plants. From time to time the 

 matted patch was thinned of its superfluous and older plants 

 and still the newest plants, even after a lapse of' seven seasons, 

 continued to produce flowers like those of the original plants.
