June /44/ The diffusion of a species into six regions (or its pre-existence in one great region before its division) shows it has some advantage— over antagonist species; & yet such diffusion is the contingent of six species of a genus being formed. — (This applies only to distribution) Hence flourishing species must be the parent of new forms & not dying species — But flourishing species generally in great numbers, wh is opposite to my view.

— Flowering in small district, most fertile source of new forms.
