hickory native to the easternUnited States and southeastCanada , fromMinnesota , southernOntario andVermont south to easternTexas and northernFlorida .It is a large
deciduous tree , growing up to 35 m tall (exceptionally to 47 m), with a trunk up to 1 m diameter. The leaves are 15-30 cm long, pinnate, with 7-11 leaflets, each leaflet lanceolate, 7-13 cm long, with the apical leaflets the largest but only slightly so. Theflower s are small wind-pollinatedcatkin s, produced in spring. Thefruit is a very bitter nut, 2-3 cm long with a green four-valved cover which splits off at maturity in the fall, and a hard, bony shell. Another indentifying characteristic is its bright sulfur-yellow winter buds. No other hickory has this feature.It is closely related to the
Pecan , sharing similar leaf shape and being classified in the same section of the genus "Carya" sect. "Apocarya", but unlike the Pecan, it does not have edible nuts. It is most readily distinguished from the Pecan by the smaller number of leaflets, with many leaves having only 7 leaflets (rarely fewer than 9, and often 11-13, in the Pecan). Hybrids with the Pecan are known, and named "Carya × brownii".Uses
Like other hickories, the
wood is used for smokingmeat , and by Native Americans for making bows.External links
