146 ALTERATION OF 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. 

Fic. 66.—Flower of Dianthus sp., calyx removed; petals turned down 
so as to show the stalked flower-buds springing from their axils. 
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 ovules. 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 1s quite natural to expect 
that they will partake likewise 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 Leguminose, and seems to 
have been more frequently met with in T7ifoliwm 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
