Petalonia fascia (O.F. Müller) Greville
Description: Plants with olive or yellow-brown laminate or ribbon-like fronds to 300 mm long; margins slightly wavy. Narrows to a short stalk and attached by a small disc.
Habitat: Generally growing on stones and shells in shallow pools in sheltered places, particularly in harbours; found mainly in sping and early summer.
Distinguishing features: Thin, relatively delicate, fronds not mucilaginous and the absence of claw-like holdfast serve to distinguish this species from young kelps.
Common names: Sea Petals, Broad Leaf Weed.
