Description:
Dark red, frequently becoming yellow-green above, thick, flattened cartilaginous fronds, arising in groups of small, medium and large from a thick, discoid holdfast, obtuse, ovate with tapered base, to 500 mm long, 250 mm broad. Reproducing in Dec-Jan.

Habitat:
On rock in shady pools, lower intertidal on rock, and shallow subtidal to 25 m, usually on rock in kelp forests; widely distributed, common.

Similar species:
This is the thickest and most cartilaginous of the broad, leaf-like species. Could be confused with Schizymenia dubyi and Kallymenia reniformis, both of which are thinner and softer. Young plants are characteristically ligulate. Palmaria palmata has usually one or more narrow dichotomies and is thinner and more slippery.
