These "races" of Onderdonk and Price, then, by leaving out the peach-floras of many regions, are too exclusive, but it is no less true that they are too inclusive. Thus, the many varieties of the historic peach of western countries are put by the Onderdonk classification in the Persian race. So considered, this Persian race contains types quite as widely separated from each other as are the five "races" of the Onderdonk classification. In one great group are collected early, late, white-fleshed, yellow-fleshed, red-fleshed, globular, oblong, beaked, hardy and tender, vigorous and dwarfish peaches. Persian peaches run the whole gamut of peach-characters, the flatness of the Peento possibly excepted, and from the several hundred sorts a score of "races" might be made. These peaches are noted by Price and Onderdonk as requiring a long period of rest and as succeeding only in northern climates. Yet to this group belong the peaches of France, Spain and Italy; those of the warm parts of Africa, South America and Oceanica; and most of the varieties that thrive at the most northern limits of peach-growing in Europe and America. The Onderdonk classification, in assigning zones to each of its five races, misleads peach-growers as to the hardiness of varieties. It makes the Peento and honey-flavored peaches much more tender in tree than they are. Varieties of both groups grow as far north as this Station and Waugh reports that one of the Peento varieties "was discovered growing thriftily and fruiting nicely on the grounds of the Massachusetts Agricultural College, Amherst, Massachusetts."[189] Of the score of descendants of the Honey, several are fruiting well on our grounds, four being illustrated and described in _The Peaches of New York_. If there were a demand for honey-flavored peaches, climate would not prevent their culture in New York. The name used for the Peento group, if it be worth while keeping these peaches in a group, is inapt. It gives the impression that all, like Peento, are flat peaches--in fact Price several times so publishes them--whereas of the twenty-three sorts described by Hume,[190] though nearly all are seedlings of Peento, only Peento is flat. We must look upon the Peento as a peach-monster similar to the cleft peach, _Emperor of Russia_, the nippled peach, _Teton de Venus_, the _Perseque_ with its teat-like protuberances, or the more familiar snow-white and blood-red varieties. We are not able to see where the Peento group leaves off and the Honey group begins in the Onderdonk classification, though, since varieties of the Peentos have not fruited at Geneva and the several Honey-flavored peaches, though both thrifty in tree and fruitful, are possibly not typical, we ought not to be too critical. As we read the descriptions made by others, however, we are struck by the fact that there are more similarities than differences in the two groups and that the differences are rapidly disappearing through hybridization.
