Description
Color: Dark purplish-red, red, yellowish or greenish fronds.

Cartilaginous, 150 mm high, gametophyte plants are often iridescent under water when in good condition. Stipe compressed, narrow, expanding gradually to a flat, repeatedly dichotomously branched frond, in tufts from a discoid holdfast. Axils rounded, apices blunt or subacute, frond thicker in center than margins. Very variable in breadth of segments. Very variable in branching, color and thickness.

Vegetative reproduction is rare; asexual reproduction is effected by the formation of various kinds of spores. Sexual reproduction is unique in this group due to their passive, non flagellated sperm cells (spermatia).
