Notes

The specimen of E. macrophyllus subsp. macrophyllus, listed by Haynes & Holm-Nielsen (1994: 57) as originating from Guyana, is from Brazil.
Jonker (1968: 378) treats E. grandiflorus (Cham. & Schltdl.) Micheli var. floribundus (Seub.) Micheli (= E. grandiflorus subsp. aureus (Fassett) R.R. Haynes & Holm-Niels.) as occurring in Suriname. The only specimen he mentions, however, belongs to E. macrophyllus subsp. scaber.
In the Guianas only: subsp. scaber (Rataj) R.R. Haynes & Holm-Niels.
