The Plants+HC+SAR megagroup is a group of eukaryotes proposed by Burki et al. (2008).[1]

It includes:

This description includes all Bikonts that are not excavates. It is also referred to as Diaphoretickes or the SAR/HA Supergroup. It is not to be confused with Corticata, which was part of a different classification scheme that excluded Rhizaria from the SAR supergroup.

It was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates.[2] However, this description is obsolete, largely due to the discovery that chromalveolata was not monophyletic.


It includes most of the species engaging in photosynthesis, except for the Euglenozoa and Cyanobacteria.
