The Chlorophytina are a proposed basal Tetraphytina clade.^[2]^[3] It is currently seen as sister of the Pedinomonadaceae. It contains the more well-known green alga and is characterized by the presence of phycoplasts.

Below is a consensus reconstruction of green algal relationships, mainly based on molecular data et al.^[4]^[5]^[6]
