GREEN. { Greenish-blue. | Yellow-green. } { Blue. | Yellow. } Cyanic series. { Blue-violet. | Yellow-orange. } Xanthic series. { Violet. | Orange. } { Violet-red. | Orange-red. } RED. The type of the cyanic series is blue, and that of the xanthic series yellow. The first is sometimes denominated the deoxidized series, and the second the oxidized, but these designations have hardly solid enough foundations to be preserved. De Candolle, who publishes the table in his Vegetable Physiology, appends some interesting remarks to it. It will be noticed by the inspection of the table that nearly all the flowers susceptible of changes of color, as a rule, simply go up or down the scale of shades of the series to which they belong. Thus, in the xanthic series the flowers of the _Nyctago jalapa_ may be yellow, yellow-orange, or red; those of _Rosa eglantina_ yellow-orange or orange-red; those of nasturtium from yellow to orange; the flowers of _Ranunculus asiaticus_ present all the colors of red up to green; those of the _Hieracium staticefolium_, and of some other yellow _Chicoraceæ_ and of some _Leguminosæ_ like the lotus, become greenish-yellow when dried, etc. In the cyanic series the flowers of many _Boraginaceæ_, especially of _Lithospermum purpureo-cæruleum_, vary from blue to violet-red; those of hortensia from rose to blue; the ligulate flowers of the asters from blue to red or violet; those of the hyacinths from blue to red, etc. There are, however, a few apparent exceptions to this rule. Thus, although the hyacinths usually vary only in the blues, reds, or white, yellowish varieties, indicating an approach to the xanthic series, are sometimes found in gardens. The auricula, which is originally yellow, passes to reddish-brown, to green, and to a sort of violet, but never reaches pure blue; and single petals occasionally give suggestions of both series in distinct parts of their surfaces.
