This species is endemic to Cambodia and only known from the type collection ( Fig. 2 ). A gathering included in Lecomte’s original material of D. tamiriensis from Laos [ Massie s.n. (P[P00721748])] belongs to D. strigosa Hemsl . Notes Diospyros tamiriensis is resurrected here from synonymy of D. apiculata ( Phengklai 1978 , 1981 ; Pham-Hoang 1991 , 1999 ; Nguyen 1996 ; POWO 2022 ).
