NOTE. she 
With reference to the coloring of the young leaves (which are the largest) of frontispiece plate, as well as of that of the leaf 
bud just expanding on the plate of opening flower, some explanation seems necessary, that this may be rightly understood. When the 
leaf bud comes to the surface of the water, it is of a pale yellow color. If the day be bright and clear, it soon changes to a dull red; 
the second day, the sun shining bright, this red changes to a light or crimson hue. So rapid are these changes that on the third morning 
the bud will be found unfolding and of this brilliant coloring, with the green appearing only in the centre of the leaf, By evening the 
crimson has changed to the green, tinges of it only remaining on the lines that mark the ribs and on the suture. These changes and the 
brilliancy of the coloring are dependent upon the action of the sun’s rays, varying greatly as this is hindered by clouds or other obstructions, 
To illustrate all these changes would require so great an additional number of plates as to render the work so expensive as to be of little 
value for general observation. Looking upon the plant the following day, only green leaves or the surface of them would be seen, (the 
edges on the under side being always colored,) and any one naturally would suppose the crimson coloring an exaggeration. I have seen 
both the leaves and the leaf bud when the coloring has been more brilliant than represented. They vary in the manner of change; the 
green usually appears first in the centre and spreads out, but sometimes it appears on the outer edge of the young leaves at the same time 
as on the centre, thus forming a crimson ring ; a few hours will change the whole to green.
