For the derivation of Campanula, see No, 963. 
The double Campanula, which we now figure, is 
not alone a novelty, but a showy ornamental border 
flower, which, being completely hardy, may be termed 
in modern phraseology, a plant for the million. 
The doubling of flowers is a somewhat interesting 
. # O 
inquiry, one which is as little understood as any 
that comes under the investigation of the physiolo- 
gist. “ I confess myself unable,” says Dr. Lindley, 
“to discover, either in the waitings of physiologists, 
or in the experience of gardeners, or in the nature of 
plants themselves, any sufficient clue to an explan- 
ation of the causes to which their origin may be 
ascribed.” 
There appears, in flowers having many stamens, 
to he a greater tendency to become double, than in 
those having few. Roses, Hepaticas, Poppies, &c., 
may be mentioned ; and in these the stamens be- 
come petals ; but in some flowers, as in the Ranun- 
culus , the pistil becomes metamorphosed into petals ; 
whilst in the Cowslip, the calyx becomes the change- 
able appendage. Here are ample subjects of inves- 
tigation for the curious inquirer.
