Ohio Trees - Key to Carya Species

Various Hickories

Red Hickory Identification - by Jess Riddle
Separating red hickory from pignut hickory has been the biggest
challenge for me in identifying trees in the eastern US. Depending on
which author you follow, red hickory is a either a separate species, a
variety of pignut hickory (C. glabra var. odorata), or just a bunch of
pignut hickories that look a little different. I think the most
definitive characteristic is supposed to be the dehiscence of the
fruit; the husk stays attached to the nut in pignut but in red the
sutures split freely to the base and sections of the husk may fall
off. Then there's a host of other characters that are often mentioned
but don't seem consistent: pignut usually has five leaflets and red
usually has seven, red hickory leaves are spicy-aromatic when crushed,
the petiole (leaf stem) is reddish on red hickory, and the bark may be
scaly on red hickory. Trees that I suspect of being red hickory also
tend to grow in fairly rich sites and the fruits are slightly
flattened spheres rather than the pear shaped nuts of pignuts. I only
occasionally see reds with strips of bark peeling of the trunk, but
the bark ridges do consistently have sharp rather than rounded edges.

Cool. Learning to differenciate the various hickory species is something I need to learn.
