OF THE OVULES. 



271 



M. van Tieghem's conclusion^ from the examination 

 of flowers of TropcBolum majus, in which the ovules 

 were replaced by perfect peltate leaves, is that the 

 ovules are foliar productions springing, not directly 

 from a prolonged floral axis, as in Primulacecey but 

 from branches of the axis arising from the axils of the 

 carpellary leaves. 



Phyllody of the ovules has been met with most often 

 in the following species : 



Aquilegia vulgaris ! 

 Skinneri, 



Delphinium crassicaule.
