A digression may be permitted here to state a hypothesis suggested by De Candolle[15] which should interest both fruit-growers and plant-breeders. De Candolle, while considering the two species of cultivated cherries to be now quite distinct, suggests that, since they differ essentially but little in their characters and since their original habitats were in the same region, it is probable that one species came from the other. He surmises, since _Prunus avium_ is the commoner in the original home, is generally the more vigorous of the two, has spread much farther and probably at a much earlier date from the primal habitation in Asia Minor than _Prunus cerasus_, that the latter, the Sour Cherry, is derived from the Sweet Cherry. In the future breeding of cherries confirmatory evidence of such a relationship may be obtained though, should none be found, the negation should go for naught and the supposition can only remain an interesting and plausible hypothesis. [15] De Candolle, Alphonse _Origin of Cultivated Plants_ 210. 1885. THE CHERRY IN ITALY Pliny attempts to give the first full account of cultivated cherries and, even though among his statements are several inaccuracies, yet he may be said to have made a very good beginning of a flora of cultivated cherries for he names and describes ten varieties. The fact that there were as many as ten cherries in Italy at the time Pliny wrote, less than a century after the return of Lucullus from Pontus, is strong evidence that the cherry in Italy antedates Lucullus. Besides, it is hardly probable that Pliny knew and described all of the cherries to be found in the whole of his country. But even if these ten comprise the entire number, those who know how extremely difficult it is to introduce new plants in a country with the facilities we have in our day, will doubt that all of the cherries in Pliny's account could have been introduced in Italy 1900 years ago and have come under general cultivation, as according to Pliny they had, within the short space of a century. The following quotation, then, must be taken as an account of the cherries grown in Italy in the first century after Christ with little weight given to the historical evidence presented.[16]
