Colony stolonal, hydrorhiza reptant on substrate, stolons tubular, faintly rugose to smooth, perisarc relatively thick. Hydrothecal pedicels scattered along hydrorhiza, hydrocaulus erect, cylindrical, unbranched, of same diameter at base as hydrorhiza, diameter increasing distally, perisarc thin with several obscure corrugations above base, continuing upwards for variable distance, corrugations gradually becoming indistinct then fading out. Hydranth long spindle-shaped, extending well above hydrotheca, hypostome high-domed, quadrate when viewed from above, with 8-10 long tentacles in a single indefinite whorl held out stiffly below hypostome.

The hydrothecae vary considerably in length within and amongst the colonies, shorter hydrothecae having a slightly thicker and more visible perisarc while longer ones usually have a thinner, sometimes almost invisible perisarc. The perisarc is often lightly coated with fine sediment. The hydranth is very active, bending from side to side when disturbed; one was observed capturing and ingesting a small amphipod. When the hydranth is extended the tentacles are scattered over the distal body region but when contracted they appear as an indefinite whorl.
