It has been supposed to be a seminal hybrid or graft-hybrid between C. laburnum and C. purpureus.

To sum up the foregoing facts: the statement that _Cytisus adami_ originated as a graft-hybrid is so precise that it can hardly be rejected, and, as we have just seen, some analogous facts render the statement to a certain extent probable.

We will now consider the few facts which have been recorded in support of the belief that a variety when grafted or budded on another variety sometimes affects the whole stock, or at the point of junction gives rise to a bud, or graft-hybrid, which partakes of the characters of both stock and scion.

In regard to the bizzarria, many authors believe that it is a graft-hybrid; Gallesio on the other hand thinks that it is an ordinary hybrid, with the habit of partially reverting {392} by buds to the two parent-forms; and we have seen in the last chapter that the species in this genus often cross spontaneously.

The most reliable instance known to me of the formation of a graft-hybrid is one, recorded by Mr. Poynter, [927] who assures me, in a letter of the entire accuracy of the statement, _Rosa Devoniensis_ had been budded some years previously on a white Banksian rose; and from the much enlarged point of junction, whence the Devoniensis and

He has also succeeded in making a true graft-hybrid between two varieties of potatoes, in which I failed.

If I had succeeded in making a graft-hybrid of the potato, I had intended to raise seedlings from the graft-hybrid and from the two parent-forms (excluding insects) and carefully compare the offspring.

a change of this kind cannot be considered to be of the nature of a graft-hybrid.

I sincerely congratulate you on your success in making a graft-hybrid (206/1.
