[Footnote 18: According to botanical authorities, the honey locust is polygamo-dioecious; that is, it generally has most of its male flowers on one tree and most of the female flowers on another tree, but the trees are not 100 per cent pure in this sex division. In my personal observations of flowers on grafted trees, including Millwood and Calhoun and scores of seedlings, both "male" and "female," I never found any pollen produced in flowers of the "female" trees, but nearly all "male" trees in the Tennessee Valley will have occasional catkins with one or more perfect flowers near their terminal ends (the basal flowers being staminate on the same catkin.) The functionally perfect flowers on such "male" trees have been observed to set from one to many pods in certain years, but such pods are generally small as compared with those borne on "female" trees in the same locality, and I have never observed a heavy pod crop on any "male" tree. Grafted trees of Millwood and Calhoun selections in Tennessee were observed to set pistillate flowers, but no pods (or very few) matured on them unless there was a "male" tree in flower within insect-flight distance from them. (At Auburn, Alabama, there were wild honeylocusts, including "male" trees, within a half-mile of the Hillculture planting of grafted honeylocusts when I saw it in 1943.) I do not argue that no pollen is ever produced by Millwood or Calhoun flowers some probably is (though its demonstration might require almost microscopic examination, in contrast with the easy finding of pods on "male" trees.) But, in the practical culture of fruiting honeylocusts, and in our present scope of knowledge of their pollination requirements, our plantings should include a handful of seedling (thornless) trees or else some grafted trees of a thornless "male" selection such as the Smith, in a ratio of about 1 Smith to 10, say, of Millwood. It is unfortunate that the presumed male mutants of the fruiting varieties, reported above by Mr. Moore, were destroyed when the Hillculture plots at Auburn were discontinued. Perhaps similar ones will show up elsewhere, and they will be worth looking for. Meanwhile, the Smith variety (originally propagated through a mixup in scionwood collection), has been demonstrated to be a satisfactory pollinator for Millwood and Calhoun, and it, as grafted, is also a thornless tree. Perhaps any thornless male seedling honeylocust tree, if its flowering period coincides with that of the fruiting variety, might serve equally well.--Note by J. C.
