Namaceae

In the 2016 APG IV system, the order Boraginales has only one very broadly circumscribed family Boraginaceae. Although Boraginaceae was known not to be monophyletic, there was insufficient support to divide up the family.^[2] Following the publication of APG IV, a collaborative group, the Boraginales Working Group,^[3] published an alternative taxonomy based on the phylogenetic relationships within the Boraginaceae s.l. This divided the order Boraginales into 11 families, including Namaceae.^[3][4][5] As of March 2026^[update], Namaceae was accepted by many taxonomic sources,^[1][6][7] but not by Plants of the World Online, which places the genera of Namaceae in Boraginaceae.^[8] A 2025 phylogenetic analysis based on both genetic and morphological data suggested that Namaceae should be re-included within Hydrophyllaceae.^[9]

As of December 2025^[update], the following three genera were accepted by World Flora Online:^[1]

• Eriodictyon Benth.
• Nama L.
• Wigandia Kunth
