Plants+HC+SAR megagroup

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

It includes:

• Plants
• Hacrobia (the "HC" refers to Haptophyta and Cryptophyta, the two major members of this group)
• SAR supergroup

It has also been described as the sum of Archaeplastida, Rhizaria, and chromalveolates.^[2] However, this simply refers to a different way of grouping the same organisms, 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.
