see text The Palmophyllales are a deep-branching order of thalloid green alga, containing the single family Palmophyllaceae.

They possibly form a sister group to the Chlorophyta.

They survive today in deep waters, and can be found at 210 meters below the surface, where predation pressure is reduced.

[1] The group contains the genera Palmophyllum, Verdigellas and Palmoclathrus.

[2] The morphology of Palmophyllales is unusual in that they are composed of cells in a gelatinous matrix, so they are multicellular, but not in a conventional way.
