The results recorded here and in the earlier work form a concordant body of facts concerning surface character which the scheme of factor relations here suggested enables us to bring together into a comprehensible whole. These factor relations involve five factors—

The single form is usually hermaphrodite, but as in the Carnation certain individuals become female through abortion or suppression of the stamens.
Double flowered individuals are on the other hand mostly female owing to complete petalody of the androecium.
When simple petalody occurs unaccompanied by splitting the double usually shows 15 petals in three alternating whorls of 5 each. In individual flowers oreven heads of flowers on such plants the petaloid modification may however be incomplete, and some stamens with normal pollen may be formed, the number of ‘petals’ in these flowers being then correspondingly fewer. Double-flowered plants showing some of these incompletely double flowers behave however as regards the transmission of the double character like the purely female doubles in which petalody is complete.
In other cases petalody is accompanied by a certain amount of splitting, thus giving rise to more than 15 ‘petals.’ In extreme cases the flower becomes monstrous with an abnormally large ovary.
All the doubles investigated when fertilised with pollen from incompletely double flowers yielded only double offspring.
