The synopsis given in Part 1:2–4 needs some modifications due to further work and the correction of errors, particularly in the authorities; these changes and some additions are detailed below (see also Darwin in Taxon 25: 595–610 (1976)). Publication of Robbrecht & Puff, A survey of the Gardenieae and related tribes (Rubiaceae), in E.J. 108:63–137 (1986) was too late for the consideration of any adjustments to the generic arrangement but notes are included as necessary.
