Robust, compressed, erect fronds with multiple branches. Fronds have a central thickening, which becomes a midrib (costate) towards base. Branchlets (ramuli) occur in alternate pairs and curve strongly inwards. Outer edge (margin) of branchlet is serrated. Base lies flat on surface (prostrate). Reproductive stichidia clustered. Pink to medium-red. Up to 25 cm long (thallus).
When reproductive, a distinctive feature of this alga is a specialised branch (stichidia), which bears clusters of reproductive structures on short stems.
