SAR supergroup

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:
