Nomenclatural notes
The correct author citation of this species is (Roth) C.Agardh since the proposal put forward by Irvine & Brodie (1997) to conserve the illegitimate name Ulva purpurea Roth, against the legitimate Ulva purpureo-violacea Roth, was approved at the XVI International Botanical Congress (St. Louis, Missouri, 26-30 July 1999) (Barrie & Greuter, 1999).

Taxonomic notes
See Brodie et al. (1996) regarding the name and selection of a neotype. According to Guiry (1997) this species requires taxonomic reinvestigation and recommends consulting Kornmann & Sahling (1991).

Habitat notes
Intertidal zone (Selivanova & Zhigadlova 2009). - (10 May 2010) - Wendy Guiry

Usage notes
High antioxidant activity (Zubia et al. 2009). - (24 Mar 2010) - Wendy Guiry

General environment
This is a marine species.
