Common names

(as Rhodymenia pseudopalmata (J.V.Lamouroux) P.C.Silva)
English: Rosy Fan Weed (Bunker & al. 2010).

Flattened, fan-shaped, rather stiff, rose-red fronds, to 100 mm high, with long or short stipes arising from a discoidal base. Fronds repeatedly dichotomously lobed, axils wide, apices rounded, margin smooth.

On rocks, shady pools, lower intertidal and subtidal (to ? m), also epiphytic on Laminaria hyperborea stipes, south and west coasts, frequent.
