## Description

Marginariella species consist of a holdfast bearing multiple blades. The margins of the blades bear receptacles and, in the case of M. boryana and M. urvilliana, pneumatocysts. The presence and form of the pneumatocysts can be used as a character to differentiate among the species.[4]

## Etymology

The genus was initially named Marginaria as it bears floats and receptacles on its frond margins. This name was later found to be preoccupied by a genus of ferns, thus the algae were renamed Marginariella.[2]

## Taxonomy

Marginariella contains the following species:

* Marginariella parsonsii[1]
* Marginariella urvilliana[1]
* Marginariella boryana[1]
