Vaccaria, Gen. Pl.: 3. 1776 sec. Bittrich (1993c)
One or four species, native to Eurasia. While usually thought to be closely related to Saponaria, both Harbaugh & al. (2010) and Greenberg & Donoghue (2011) found a potential relation with Gypsophila based on different vouchers; sister to Gypsophila in the former study, clustering near the base of a Gypsophila clade in the latter.
