Discussion
Brayodendron, based on Diospyros texana and segregated because of its apically dehiscent anthers, lack of staminodes, and coherent styles, can hardly stand up within a worldwide view of the Ebenaceae. As well as being eaten by people and wildlife, the fruits also are used in dying. The heartwood turns dark sooner than in D. virginiana; the small size of the stems limits its use.
