Classification Notes:
- In this account, the concept of Drimiopsis includes that of the genus Resnova
- This differs from Müller-Doblies & Müller-Doblies (1997) where the genus Resnova is resuscitated and is separated from Drimiopsis by its ± spreading tepal lobes, biseriate stamens, subulate filaments and longer perianth
- Several new species of Drimiopsis were also described in this publication, but before these can be incorporated type material/cited material needs to be accessible
