ties of almost any conceivable color, under culti- 
vation and careful selection. 
Another striking exception, and one which 
would have puzzled De Candolle for its color 
classification, is the columbine. One common 
species of the Eastern United States, Aquilegia 
canadensis, is of a pure deep scarlet color, as every 
country boy knows. If we seek for our colum- 
bines in the far West we shall miss this familiar 
type, and find it replaced by another species, A. 
chrysantha, of a fine clear yellow, or perhaps by 
its near relative, the A. ccerulea, with its sky-blue 
corolla, a common species in the region of the 
Rocky Mountains. Columbines, red, yellow, and 
blue, are thus to be found in a state of nature, 
and we thus find other cultivated forms which ex- 
tend from a pure white through all shades of 
purple. 
The pansy, that protean offspring from lowly 
"johnny- jumper," occasionally comes very near 
embracing the entire gamut of color to which its 
name, Viola tricolor, would seem to entitle it. 
Blue pansies and yellow pansies we certainly have, 
but the ruddiest of its rich wine tints, -when laid 
beside the red, red rose, at once confesses its pur- 
ple, the remnant of blue which it cannot absolutely 
eliminate. 
The blue rose, blue tulip, blue dahlia, and blue 
carnation have as yet refused to respond to the
