Howard (1964, mss.) reported Diospyros blancoi A.L.
Candolle (as Diospyros discolor Willdenow, nom. illeg.) and
Diospyros ebenum Koenig on Dominica. Both would be

digynu Jacquin was collected in the Roseau Botanic Garden (J.
Jones s.n. at K, introduced from Mexico). Diospyros mlaburica
(Desrousseaux) Kosteletzky (as Diospyros embryopteris
