Due to entanglement of the stems it is difficult to decide if one or many colonies are present. The few hydranths are in very poor condition, due either to damage during collection or senescence of the colony. The species is distinguished by its strictly monosiphonic, shining brown stems and paired chain of immature gonophores.

Although Hartlaubs description of the species is brief I have no doubt that the present specimens are referrable to

. Like much of the present material, Hartlaubs specimens apparently comprised bare stems lacking hydranths or reproductive structures. The thin brown stems, as described and figured by Hartlaub are characteristic. The species has not been recorded since its first description.
