Isonandreae T.D. Penn., Gen. Sapotac.: 147. (1991)
- Isonandra Wight (1840)
Note: Isonandra was not tested by Smedmark et al. (2006) due to lack of material. However, the other genera were found by them to be related and therefore this circumscription follows Pennington (1991) with the addition of Northia.
