Colonies with the appearance of a gorgonid, up to 38 cm high and for a large strongly polysiphonic. Hydrorhiza disc shaped or composed of a few thick stolonal tubes. Branching beginning at base of colony, in one plane and frequent, usually irregular, but sometimes alternate. Branches long, flattened arising branches from which they originate. Many basal branches also polysiphonic.
Length is based on colonies height. Inhabits stones, gravel and sand (Ref. 7414).
