Speaking of Double Stock-gillies, M. Chote in a French paper translated by the Gardener's Clironicle, says:

"Every time that I have had a single flower, in which one or more stamens were adhering to the petals, complete duplication was not long in making its appearance, whether these flowers were fertilized by pollen from a double or semi-double flower, or whether we cut off the latter so as only to collect seeds from the former;" and we may add this as is true of all kinds of flowers as of the Stock-gilly.
