**Namaceae** is a small family of [flowering plants](/source/Flowering_plant) in the order [Boraginales](/source/Boraginales) with three accepted genera as of December 2025.[1] Its taxonomic status remains unclear as of March 2026. Some sources place its genera in a broadly defined Boraginaceae. A 2025 paper suggested that it should be re-included within Hydrophyllaceae.

## Taxonomy

In the 2016 [APG IV system](/source/APG_IV_system), the order Boraginales has only one very broadly [circumscribed](/source/Circumscription_(taxonomy)) family [Boraginaceae](/source/Boraginaceae). Although Boraginaceae was known not to be [monophyletic](/source/Monophyly), 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](/source/Phylogenetics) relationships within the Boraginaceae *s.l.* This divided the order Boraginales into 11 families, including Namaceae.[3][4][5] As of March 2026, Namaceae was accepted by many taxonomic sources,[1][6][7] but not by [Plants of the World Online](/source/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]

### Genera

As of December 2025, the following three genera were accepted by [World Flora Online](/source/World_Flora_Online):[1]

- *[Eriodictyon](/source/Eriodictyon)* Benth.
- *[Nama](/source/Nama_(plant))* L.
- *[Wigandia](/source/Wigandia)* Kunth
