This list does not include those very numerous cases 

 in which this change is associated with more or less 

 complete frondescence or leafy condition of the petals. 



Dialysis of the stamens. A similar isolation of the 

 stamens occurs occasionally; for instance, when Mallows 

 {Malvacece) become double, one of the first stages of 

 the process is often the disjunction of the stamens, and 

 a similar dissociation occurs in Leguminosce and Com- 

 positcEi as in Tragopogon, as related by Kirschleger, 

 in Hypochaeris by Wigand, and in Coreopsis by Schlech- 

 tendal. 



Dialysis of the carpels. In the case of the carpels this 

 disunion is more frequent than in the stamens. M. 

 Seringe^ figures carpels of Diplotaxis tenuifolia more or 

 less completely separated one from the other ; indeed, 

 this separation is very common amongst Cruciferce and 

 JjTnhelliferce . 



Generally speaking, the disunion is complicated with 

 frondescence but not always so. I have, in my her- 

 barium, specimens of Convallaria majalis, Coinmelyiia 

 sp.y and of Lilium auratum, in all of which the three 

 carpels are completely disjoined, and present three
