The col- oration here, as in dracfenas and caladiums, is intensitied by strong light and nourishing food. The more of the modified cliloroph}' there is produced and the more rapid the changes in the modified chlorophyll brought about through the action of light and the acids and oxidizing ferments of the leaves, the more highly developed vvill be the colors, though here again high feeding is likely to cause the plant to revert to its normal condition. Variegated plants or parts of plants are usually of slower growth and smaller than green plants of the same variety or the green parts of the same plant. Causes of Variegation. —Varie- gation occurs either by bud-varia- tion or by variations in seedlings. In the former, a variegated branch is likely to appear on an otherwise perfectly normal plant. Such varie- gations are easily reproduced by budding, grafting or cuttings, but generally do not develop again from seeds produced on such branches. On the other hand, when variegation develops in seed- lings, the seeds of such plants usu- ally give a number of variegated individuals, even the cotyledons being sometimes affected. In some cases the proportion of varie- gated plants from seeds is very large and can be increased by selec- tion. As a rule, the form of spot ting or marking ix not tonstn in seedlings, often being very dift i ent from ilie parent. In ceit in groups of plants, which have for m
