of being represented by the flat blade of a single leaf, 

 had the appearance as if two such blades were present 

 and coherent one with the other by their midribs, 

 along their upper or inner surfaces, which were directed 

 towards the centre of the flower (fig. 136), thus resem- 

 bling the cases of adhesion of leaves by their surfaces 

 already referred to (p. 33). In other cases, in the same 

 plant, the anther appeared as if formed by two collateral

leaves, the faces looking towards the circumference of 

 the flower, and their margins so folded together as 

 to represent an open anther lobe (fig. 135). These 

 cases are apparently due, not to the formation and 

 adhesion of two leaves, but rather to the exuberant 

 development of one leaf into two blades.^ The bear- 

 ings of these and other similar malformations on the 

 morphology of the anther are alluded to under the 

 head of petalody of the anther. 



Phyllody of the stamens has been most often observed 

 in the following plants :
