C. ovalis (Wangenh.) Sarg.
Red Hickory ranges farther west than pignut hickory, being found across southern Missouri into northeastern Oklahoma and across northern Arkansas (distribution map). C. glabra is distinguished by its glabrous leaves, usually with 5 leaflets, its pyriform fruit with smooth husks which are only partially dehiscent, and by the tight bark of mature trees. C. ovalis shares the feature of glabrous leaves, but usually has 7 leaflets. It has warty husks which dehisce to the base along sutures which are often somewhat winged. The bark of mature trees sheds in long thin strips.C. ovalis has warty husks which dehisce to the base along sutures which are often somewhat winged.
Two cultivars have been named of C. ovalis, 'Green' and 'Huff', both of southern Michigan and both named in 1929 (Grauke, 1988).
C. X demareei Palmer was described as a cross between red hickory and bitternut.
