of longer stamens are almost of equal length and this length is 

 about midway between the two lengths characteristic of the 

 mid- and the long-lengths as seen in long- and in mid-styled 

 plants. It is to be noted that the long stamens of the short- 

 styled form (fig. i) are as a rule somewhat shorter than are the 

 long stamens of the mid-styled form (fig. 2). The stigmatic 

 lobes of the pistils of the new form are as large or even larger 

 than those of long-styled plants and considerably larger than 

 the stigmas of mid-styled plants (compare figs. 3, 4 and 6 with 

 5 and 2). The new form may be considered as homomorphic 

 for the lengths of the pistil and the set of longer stamens but 

 there is also a set of short stamens so it may be designated as a 

 semi-homomorphic form. 



The first plant having flowers of this new type appeared 

 among the self-fertilized progeny of a mid-styled plant. The 

 other 58 sister plants of this particular series were either mid" 

 styled or long-styled with no marked deviations in lengths of 

 parts from those typical for these forms. This plant was selfed 

 by the bagging method in the first year of its bloom and found 

 to be highly self-compatible. It was then removed to my home 

 garden at Pleasantville, New York, where it was grown in isola- 

 tion from any other plant of Lythritm. It produced seed in 

 abundance to the enforced self-pollinations and from such seed 

 122 plants have been grown to blooming age, and for many of 

 these, observations on flower character have been made for three 

 years. Of these plants, 60 were readily to be classed as of the 

 new semi-homomorphic form, nine were long-styled, 52 were 

 intermediate between the new form and the long-styled and one 

 plant was mid-styled. The intermediates varied toward the 

 long-styled form in that the pistil was longer than the stamens; 

 there were none that varied toward the mid-styled form. 



Mention should be made of the wide variations in the color 

 of anthers in the flowers of these plants. The anthers of long 

 stamens and the pollen which they contain are typically dark 

 colored or purplish, sometimes described as greenish, while the 

 anthers and pollen of short- and mid-stamens are yellow. It 

 has, however, frequently been obscr\ed that some of the mid- 

 stamens of long-styled plants may be dark in color. 



In the first plant of the new form the various members of the 

 longer set of stamens were quite uniform as to length, but purple
