Hickories which have nuts with a bitter pellicle, all belong to the open-bud group. These are the bitternut, Texas hickory, and water hickory. Hickories with scaly bark are found in both groups. In the open-bud group, the trunk of the water hickory carries long loose bark strips attached by one end, and in the closed-bud group, we find this characteristic belonging to the shagbark, shellbark, Carolina hickory, and to one of the pignuts, Carya ovalis. That takes us to another occasion for a note. What do we mean by "pignut?" In the North, this term is applied to Carya glabra and Carya ovalis. In the South, it is applied to Carya cordiformis. A name so well established, will have to be retained, but in our Association it will perhaps be best to have an understanding about which one of the hickories the common name pignut should belong. So long as it already covers two species in the North as opposed to one in the South, there are already two votes to one in favor of retaining the name pignut for Carya glabra and Carya ovalis. We may describe these in plain language as the smooth-bark pignut and the loose-bark pignut. The reason for choosing the name "loose" instead of "scaly" is because we are pretty well agreed upon applying the name "scalybark" to the Carolina hickory, the name "shagbark" to Carya ovata, and the name shellbark to Carya laciniosa. The name bitternut may safely be allowed to remain with Carya cordiformis because the other two nuts with bitter pellicle already have distinctive names, Carya aquatica being called water hickory and Carya texana being called bitter pecan. By making fixed points in nomenclature in this way we may head off the confusion which will become worse confounded as the interest in hickories becomes rapidly enlarged, if our committee on nomenclature does not take some decisive step.
