In exiled species of Decandolle, the distinctness of type of species (in such cases as occur) is, I think, a strong argument against having been chance wanderer. When a genus spreads slowly over world, in most cases, the species becomes altered, owing to lapses of times & new condition, which wd not be case with a chance & sudden introduction.
