Plants+HC+SAR megagroup
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:
- Archaeplastida (or kingdom Plantae sensu lato)
- Hacrobia (the "HC" refers to Haptista and Cryptista, the two basal clades in the group)
- stramenopiles+alveolates+Rhizaria (SAR supergroup)
This description includes all Bikonts that are not excavates and Hemimastigophora. It is also referred to as Diaphoretickes (/ˌdaɪəfəˈrɛtɪkiːz/) or the SAR/HA Supergroup, or the Corticata with Rhizaria now included in the SAR supergroup.[2] The name Corticata comes from Cavalier-Smith's hypothesis about the common origin of the cortical alveoli of glaucophytes and alveolates.[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It was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates.[4] However, this description is obsolete, largely due to the discovery that chromalveolata was not monophyletic.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.
