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.
