One of the worst features of common names is one that has not been hitherto noted, namely, that people are no more satisfied with them than botanical names, and new ones come up every year or two. They will not stay named, as with botanical names they usually do. Ptelea seemed too hard, so it came to be called hop tree, the fruit making a good substitute for hops. We read recently in a western horticultural paper about the Wafer Ash. After considerable trouble we found this to be a new name given to the Ptelea. Soon there will be another name "all Greek" to the hearer as well as Ptelea. Now, this is not all a joke, for Ptelea is the Greek name for the elm tree. The seed is like an elm seed and if people want a new name still, it may come to be elm ash.
