The Archaeplastida+HC+SAR megagroup (Archaeplastida comprising the red algae, the green algae, and the land plants) 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 ( /ˌdəfəˈrɛtɪkz/)[2] or the SAR/HA Supergroup, or the Corticata with Rhizaria now included in the SAR supergroup.[3]

It was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates.[4] However, this description is obsolete, largely due to the discovery that chromalveolata was not monophyletic.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.
