Common names

(as Laurencia pinnatifida (Hudson) J.V.Lamouroux)
English: Pepper Dulse (Dickinson 1963).

Common names used in commerce, often for edible algae
; "dulse, pepper"

Description
Cartilaginous, usually markedly compressed, dark purple to pale yellow fronds, to 100 mm or more long, from discoid base. Very variable in size and form. Main axis usually simple, branching alternate distichous, repeatedly pinnate. Ultimate ramuli short, blunt.

Habitat
On rocks, perennial, throughout intertidal, often as flattened rosettes covering exposed rocks, also subtidal, generally distributed, abundant.

Key characteristics
Plants degenerate soon after collection, are more brittle than O. osmunda and O. truncata.

Similar species
Laurencia osmunda is larger and arises from spreading stolons. Osmunda truncata is less common, is more pinnately branched, generally grows epiphytically, and rapidly degenerates on collection; it is sometimes locally abundant (e.g., in the inner part of Lough Hyne, Co. Cork).
