Taxonomy
Gymnocladus (γυμνοκλαδυς) is of Greek derivation and refers to the stout branches destitute of spray.
It is one of three species in the genus Gymnocladus, the other two being native to eastern Asia. These are Chinese Coffeetree Gymnocladus chinensis in central China, and Burmese Coffeetree Gymnocladus burmanicus in Burma.
The name is sometimes hyphenated as 'coffee-tree'; the form 'coffeetree' here is as used officially by the United States Forest Service.
