Halvaria

Chromalveolata
Clockwise from top-left: a haptophyte, some diatoms, a water mold, a cryptomonad, and Macrocystis, a phaeophyte. The diatoms, water mold, and Macrocystis are halvarians.

Halvaria is a grouping that includes Alveolata and Heterokonta (Stramenopiles).[1]

Analyses in 2007 and 2008 agree that the Stramenopiles and the Alveolata are not related, yet forming a reduced chromalveolate clade. They split apart from the Rhizaria (originally one of the six major prokaryote groups) to form a clade dubbed the SAR supergroup.[2][3][4]
