146 ALTERATION OP POSITION. 



cap. 16, sect. 105 ; but in that instance median pro- 

 lification also existed. For my specimens I am in- 

 debted to Mr. T. Moore.

The pistil, too, is necessarily subject to very grave 

 alterations when affected with this malformation. It 

 is separated into its constituent carpels ; and these 

 assume a leaf-like aspect, and are in the great majority 

 of instances destitute of o^^lles. Indeed, virescence 

 or chloranthy is very intimately connected with this 

 aberration, as might have been anticipated, for if the 

 parts of the flower assume more or less of the condition 

 of stem-leaves or bracts, it is quite natural to expect 

 that they "svill partake hkewise of the attributes of 

 leaves, even at the expense of their own peculiar func- 

 tions. 



It occasionally happens that an adventitious bud 

 arises from the axil of a monocarpellary pistil. This 

 takes place sometimes in Leguminoscef and seems to 

 have been more frequently met with in TrifoUum repens 

 than in other plants. The species named is, as is well 

 known, particularly subject to a reversion of the outer 

 whorls of the flower to leaves, and even to a leaf-like 

 condition of the pistil. There are on record instances 

 wherein a leaf-bud has been placed in the axil of a
