Species:

Note: Receptacles can be present in all seasons and are narrow and often forked at the tips.

Note: This is a small (5-15 cm tall) fucoid species with no midrib or air-vesicles. Stipes is conspicuously channeled and the fronds are repeatedly dichotomously divided. The species is growing in the upper tidal zone at wave-protected and semi-exposed sites. It is very tolerant to dry conditions, and seems to be dependent of periods of drought during low tide.

Note: Specimens with receptacles growing on rock, note the channeled stipes.
