Carya texana, or black hickory, for its dark colored bark, is a North American tree in the walnut family, Juglandaceae. It is endemic to the United States, found primarily in the southern Great Plains and the Lower Mississippi Valley.[2][3] It is an endangered species in Indiana, where it occurs in the southwest corner of the state.[2]

Description[edit]

Black hickory grows up to 41 m (135 ft) tall. It has dark gray to black bark with a tight "diamond" patterning. The leaves usually have a dense coating of scales, imparting a rusty brown color. They are pinnately compound usually with seven leaflets, but sometimes five or nine. The fruits (nuts) are bronze to reddish brown and the seeds sweet and edible.[4][5]

Genetics[edit]

Black hickory is a 64-chromosome species that readily hybridizes with tetraploid C. tomentosa. Hybrids with 32 chromosomes may also occur.
