Notes.

Ridley (1911) published E. atrosanguinea from Malaysia with a full description and type specimens, but without mentioning any herbaria. Krukoff (1939) considered this a synonym of E. fusca, but he could not see the type specimens. As Ridley described its flowers as "deep red black", and the type collections were not found on digital databases, it remains as a doubtful synonym.
