interesting to observe in " Papilio " that in the primary variation 

 there was a correlation between the toothing of the corolla segments 

 and of the leaves. 



Cresting, 



The most remarkable form which has made its appearance under

 Low and Co. I quote the account of its development with which 

 they have been so good as to furnish me : —

 slightly raised rib running part of the way up the petals, and showing

" We have this year found some colour in one plant, and we
