Organism information awaits expert curation
Class: Florideophyceae

Color: Pale purplish-red, quickly degenerating when removed from the water and becoming distinctly orange.

Fronds bushy, with a cylindrical axis to1 mm wide and 200 mm long, arising from bare, creeping stolons; irregularly branched, with 4 rows of branchlets, simple, short, branchlets alternating with longer ones with 4 rows of simple filamentous ramuli. Lower branchlets unbranched, long, tapered, with harpoon-like barbs.

Tetrapsorophyte (“Falkenbergia-phase”) occurring all year round, brownish-red, much branched, filamentous, in dense cotton-wool-like tufts to 15 mm in diameter. Both phases readily reproduce vegetatively. Drift specimens of gametophyte readily attach to other algae by barbed branchlets, and produce new shoots.

Similar species: Bonnemaisonia hamifera occurs in similar habitats but has crozier-shaped attachment branchlets rather than recurved barbs.
