Loeflingia, Sp. Pl. 1: 35. 1753 sec. Bittrich (1993c)
- Type: Loeflingia hispanica
Seven species of the Mediterranean, southwest Asia, and western North America. Fior & al. (2006) and Harbaugh & al. (2010) both showed Loeflingia and Polycarpon clustering together; a result not shown in Kool & al. (2007) study of Polycarpon. Greenberg & Donoghue (2011) found it clustered in a poorly resolved clade including eleven other genera of Polycarpaeae.
