A vegetative mutation occurred in a seedling of Petunia violacea bearing otherwise normally green leaves, giving rise to a variegated sectant (see the photograph on the page 86). The seedling, registered as Pt. 261, was divided on this account into three parts, i.e., (1) G-sectant with green leave, (2) V-sectant with white-margined leaves, and (3) W-sectaut with white leaves. The white leaf lacks green chloroplasts entirely, and the white-margined one proves itself to be a whit-over-green periclinal chimera lacking green chloroplasts in the epidermis and some sub-epidermal cell-layers. In crossing each sectant with a normally green plant, resistered as Pt. 45, reciprocally (see the table on the page 87), it was witnessed that the chloroplast deficiency under cosideration is inherited through ovules only but not through pollen, and that the progeny of the crosses concerned is either normally green or albino. It is likely, therefore, that one deals in the present case with a variegation belonging to the category II, A, b in Winge's classification of variegation (1919).
