This plant as far as known is confined to the region of the upper Rio Negro and
the Rio Casiquiare. It is a riverbank tree with coriaceous obtuse leaves that dry
pale brown beneath, and flowers rather numerous and sessile in axillary glomerules.

Very similar if not conspecific is Eugenia lingua Berg, Mart. Fl. Bras. 14(1):
266, 1857. The type is Spruce 1161, "in vicinia oppidi Barra do Rio Negro" (M!;
isotypes F, G; Field Mus. neg. 19960). When in 1954 I studied the types of this
species and E. cachoeirensis I could find no differences that seemed significant. The
leaves in E. lingua are smaller, and the pedicels up to about 3 m m long.
