A tall erect colony growing up to 10 cm high, branching occasionally from alternate sides and light horn to light brown in colour. Each branch is ringed at the base and has a terminal polyp. The polyps are white to pale pink and have 12 -16 long, colourless, extensile tentacles arranged irregularly on the surface of the polyp. The mouth is born on a conical but truncated proboscis. Each branch bears one to three pear-shaped reproductive bodies on short stalks. It produces a planula larvae but no free-living medusoid stage.
