Vernacular name. – “Hazonamalo” (Andriamihajarivo 489).

Distribution and ecology. – Diospyros danguyana is known from subarid thicket and forest on sand, sandstone, and lateritic substrates from Ambatofinandrahana in the east and Ankilizato in the west, south to Tolagnaro and north of Cap Sainte Marie ( MADAGASCAR CATALOGUE, 2020), at an elevation of 20–1800 m.

Conservation status. – Diospyros danguyana has a geographic range in the form of an EOO of 125,261 km ² and a minimum AOO of 128 km ². It is present in the Analavelona, Andohahela, Isalo, and Makay protected areas. Outside of protected areas, it is threatened by fire and grazing. With respect to the principal threat of grazing, it exists at 29 locations. Therefore, D. danguyana can be assessed for its risk of extinction as “Least Concern” [LC].

Notes. – Maba enervis H. Perrier. ( Diospyros enervis (H. Perrier) G.E. Schatz & Lowry ) is here placed into synonymy under D. danguyana . Described from the northwestern portion of the overall range of D. danguyana , and thus from the transition from subarid to dry bioclimates, M. enervis exhibits leaves that are somewhat less strongly revolute upon drying, but are otherwise identical to D. danguyana in shape and size, with identical fruit completely enclosed within the cylindrical-tubular accrescent calyx. Diospyros danguyana can be distinguished from other members of the Bernieriana group by its linear leaves 4–8 times longer than wide, its elliptic to subspherical female flowers only slightly longer than wide, and its distinctly lobed accrescent calyx enclosing the fruit, the lobes 3 mm long.
