Ortegia, Sp. Pl. 1: 560. 1753 sec. Bittrich (1993c)
- Type: Ortegia hispanica
Monotypic; Italy and Iberian Peninsula. A member of tribe Polycarpaeae, but relationships vary in different studies. Fior & al. (2006) showed Ortegia in a cluster with Polycarpon and Loeflingia; Kool & al. (2007) reported Ortegia clustering with Illecebrum and Cardionema. Curiously, using the matK sequence from the Fior & al. (2006) study, both Harbaugh & al. (2010) and Greenberg & Donoghue (2011) found that Ortegia clustered with a Hawaiian collection of Drymaria cordata (L.) Willd. ex Schult. var. pacifica Mizush.
