General Description

Flat firm and tough textured alga. Several stems (axes) develop from holdfast with regular branches developing from the base of older stems, branching mostly in two equal parts (sub-dichotomous) at regular intervals on one plane (two-dimensional). Holdfast at base starts as a simple disc developing closely adjacent roots (haptera). Tan to dark brown. Up to 20 cm long (thallus).

Biology

One of the few southern Australian fucoid algae that extend to the intertidal, the fringing areas of the shore and rock pools. It is occasionally observed under dense canopies of the alga Hormosira banksii, and can have the same epiphyte growth as H. banksii, Notheia anomala.

Habitat

Tidal pools and shallow subtidal rocky reefs with moderate-rough wave action, to depth of 6 m.
