Colonies stout, upright, laterally branched, with thick, more or less clavate terminal branches.

Outermost coenenchymal sclerites small, stubby double heads, with tubercles/warts not distinctly arranged in transverse belts. Main coenenchymal sclerites larger with more distinct rays, bearing complex tubercles/warts; axial sheath sclerites as capstans, with less complex tubercles/warts. All sclerites colorless. Remarks: Specimens of this genus cannot be assigned to any other based upon the appearance of the sclerites: typically, very small surface sclerites, ... : Published as part of Horvath, Elizabeth A. & Stone, Robert P., 2018, Another unusual new gorgonian (Anthozoa: Octocorallia: Plexauridae) from the Aleutian Islands of Alaska, pp. 112-120 in Zootaxa 4524 (1) on page 113, DOI: 10.11646/zootaxa.4524.1.8, http://zenodo.org/record/2610371 ...
