Thank you Fabrizio An adaptive hypothesis given for variegation is that it fools insects into thinking that the leaves are already being attached by phytophagous insects, and that they would be better to find another place to lay there eggs. Or that by breaking up the outline of leaves it make it harder for insects to recognise them as food. I am unaware of how often, if ever, these hypotheses have been experimentally tested. In some cases variegation is due to viral infection (I don't think that the photograph represents such a case) and is presumably non-adaptive. Among the residue of cases there is more than one mechanism for variegation. -- Stewart Robert Hinsley |

I knew that's due to a virus, but I'd be wrong.
Anyway, someone can identify the plant? Thank you, Fabrizio |

Looks to me like one of the narrow-leaved varieties of Codiaeum
variegatum, commonly called "Croton." The plants come in a whole rainbow of colors. The spotted one is a mutation (sport) of one with more normally-colored leaves. Spots and stripes on leaves can be a mutation, a virus, evidence of chimaera, or damage from a pest or insect. In this case, I think it's genetic.
