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. It is an endangered species in Indiana, where it occurs in the southwest corner of the state.

Description

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 can be sweet and edible, but are sometimes bitter.

Genetics

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