accessory pigments in light capture for photosynthesis. Chloroplastida Adl et al., 2005 (Viridiplantae Cavalier-Smith 1981; Chlorobionta Jeffrey 1982, emend. Bremer 1985, emend. Lewis and McCourt 2004; Chlorobiota Kendrick and Crane 1997) Chloroplastida is the term chosen by Adl et al. for the group made up of the green algae and land plants (embryophytes). Except where lost secondarily, all have chloroplasts without a peptidoglycan layer and lack phycobiliproteins. Chlorophyta Pascher, 1914, emend. Lewis & McCourt, 2004 – green algae (part) Adl et al. employ a narrow definition of the Chlorophyta; other sources include the Chlorodendrales and Prasinophytae, which may themselves be combined.

Lewis & McCourt, 2004 (Charophyceae Smith 1938, emend. Mattox and Stewart 1984) – green algae (part) and land plants Charophyta sensu lato, as used by Adl et al., is a monophyletic group which is made up of some green algae, including the stoneworts (Charophyta sensu stricto), as well as the land plants (embryophytes). Sub-divisions other than Streptophytina (below) were not given by Adl et al. Other sources would include the green algal groups Chlorokybales, Klebsormidiales, Zygnematales and Coleochaetales.

Lewis & McCourt, 2004) – land plants (embryophytes) Cladogram Below is a consensus reconstruction of green algal relationships, mainly based on molecular data. While the Glaucophyta are typically figured as deepest rooting Archeaplastida, some genomic research points to Rhodophyta as basal, possibly with Cryptista and picozoa emerging in Archaeplastida. At least for Cryptista, this analysis (by Burki et al. 2016) has gained credibility. Later analyses suggests the (Pan-)Cryptista are sister to the Archaeplastida. However, there is a lot of contention near the Archaeplastida root, e.g. whether Glaucophyta or Rhodophyta are basal, or whether e.g. Cryptista emerged within the Archaeplastida. In 2014 a thorough review was published on these inconsistencies. The position of Telonemia and Picozoa are not clear. Also Hacrobia (Haptista + Cryptista) may be completely associated with the SAR clade. The SAR
