Solution of the stamens from the petals. A separation of 

 the stamens from the petals in flowers, wherein those 

 organs are usually adherent one to the other does not 

 often occur unattended by other changes. It has been 

 observed in Cohaa scandens (Turpin), in Antirrhinum 

 majuSy and in many double flowers. 



Partial detachment of the stamens from the styles 

 occurs frequently in semi-double flowers of Orchis?
