Vivianiaceae
Vivianiaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus Viviania Cav. It includes both the genus Viviania.
There are around 1-4 genera in Vivianiaceae, and under the APG III system the genera from Ledocarpaceae - Balbisia, Rhynchotheca, and Wendtia - are now included within the Vivianiaceae.
A relationship with Caryophyllales, was formerly suggested; but morphology and chemistry are close to Geraniales.
