Among a dozen species of American Aquilegia, three- 

 fourths of the number are yello^v, notwithstanding their 

 high development. 



Aconitum has many blue flowered species, but it also has 

 at least thirteen species or varieties of a yellow or cream 

 color ! 



We have shown that the prevailing color of numerous 

 species unquestionably simpler than the buttercups, are 

 white or purple, with several reds and many blues. The 

 remarkably developed Aquilegia is mainly yellowy and 

 while Delphinium and Aconitum have in the American 

 species the most blues, there is really very little difference 

 in colors between the species of the highest and lowest of 

 the Crowfoot family, or say between Aconitum and Clematis. 



There are to be found among the Iianunculacew an un- 

 usually large number of sjiecies having only colored sepals, 

 except that at the same time there is apparently an attempt 

 to produce real petals, with the result only of modified sta-
