Sar or Harosa (informally the SAR supergroup) is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria. The first letter of each group provides the "SAR" in the name (alternatively spelled "RAS").
The term "Harosa" (at the subkingdom level) has also been used for this grouping by Cavalier-Smith (2010).Adl et al. (2012) formalized the SAR supergroup as the node-based taxon Sar. They defined it as:
Members of the SAR supergroup were once included under the separate supergroups Chromalveolata and Rhizaria, until phylogenetic studies confirmed that stramenopiles and alveolates diverged together with Rhizaria. This apparently excluded haptophytes and cryptomonads, leading Okamoto et al. (2009) to propose the clade Hacrobia to accommodate them.
