30mm long, polysiphonic over almost its entire length. Main stem giving rise to three branches on the same side and another branch on the opposite side; branching approximately in
one plane. Hydrothecae alternately arranged in one plane, forming two longitudinal rows. Hydrothecae only slightly immersed into the branches, strongly curved outwards.
