PHYLLODY 



were similarly changed, so that it became permanent, 

 and resembled a branch. 



Substitutions of this kind form the green " eyes" or 

 centres of certain varieties of Ranunculus and Anemone. 



In proliferous roses, or in cases where the central axis 

 of the flower is prolonged, it frequently happens that the 

 pistils are more or less replaced by leaves. Fig. 137, 

 from a specimen of Dr. Bell Salter's, given in the 

 * Gardeners' Chronicle,' shows the passage, from below 

 upwards, of the ordinary carpels to perfect leaves; 

 the so-called calyx-tube being completely deficient 

 and the ovaries entirely superior. Like most similar 

 specimens, this one bears out the notion that what is 

 called the calyx-tube in roses is really an expansion 

 and dilatation of the top of the flower-stalk.
