Origin of Species Name
Adjective (Latin), edible (Stearn 1973).
This is a marine species.
Plants with olive or yellow-brown fronds to 4 m long and 25 cm wide. Attached by a root-like holdfast at the base from which a narrow flexible stipe arises which continues into the leafy part of the plant as a distinct mid-rib. The reproductive structures, apparent as dark-brown areas, are confined to unbranched leafy appendages borne on the stipe, usually in two rows. This is the only kelp-like plant in Ireland and Britain with a distinct midrib and is the only one with sporangia borne at the base of the frond in special leaflets called sporophylls.
Generally growing on rock in very exposed places, often forming a band at low water and in the shallow subtidal, but also occurring in tidal pools in the lower shore.
