CHANGES IN THE PISTILS. 87* 



the corolla there has really a tube, closely 

 embrachig the Germen. In Ado.va, t. 453, 

 tlie calyx is half-interior, the corolla su- 

 perior. When in botanical language we 

 say germen superior, it is equivalent to 

 flower inferior; but it is sometimes more 

 convenient and proper, for the sake of 

 analogy or uniformity, to use one mode of 

 expression than the other. 



Pistils are sometimes obliterated, thousfh 

 oftener changed to petals, in double flowers, 

 as well as the stamens; but I have met with 

 a much more remarkable change in the 

 Double Cherry, of the pistil into a real 

 leaf, exactly conformable to the proper 

 leaves of the tree, only smaller. By this 

 we may trace a sort of round in the vege- 

 table constitution. Beginning at the her- 

 bage or leaves, we proceed insensibly to 

 bracteas in many species of Salvia^ or to 

 both calyx and corolla in the Garden Tu- 

 lip, which frequently has a leaf half greea 

 half coloured, either in the flower or on 

 the stalk just below it. Anemone alpina 

 produces occasionally a petal among the 

 segments of its involucrum or bractea.
