Nomenclatural notes
Silva, Basson & Moe (1996: 905-906) examined the complicated nomenclatural history of this species and concluded that the correct name for the entity was Phycodrys crenata (S.G. Gmelin) P.C. Silva. However, this conclusion was strongly refuted by Wynne (1997: 330) and the name Phycodrys rubens is retained here.

General environment
This is a marine species.

Common names

(as Phycodrys rubens (Linnaeus) Batters)
English: Sea Oak (Bunker et al. 2010).

Swedish: Ekblading (Tolstoy & Österlund 2003).

Description
Flattened, leafy, purple-crimson fronds, to 300 mm long. Cylindrical stipe continues as midrib of elliptical or ovate blade, membranous and monstromatic except for pinnate paired lateral veins extending into lobes of blade. Marginal lobes grow into secondary blades, which may in turn develop tertiary blades,each sinuate or lobed like oak leaf. Margin sinuous, toothed or drawn out into slender, repeatedly divided processes.

Habitat
On rock or epiphytic, especially on Laminaria hyperborea stipes, lower intertidal pools and subtidal, generally distributed, common.
