[segment L:B 0.6–0.75]. Nodes with 6–8 periaxial cells, each cutting off 2 acropetal and 2 basipetal cells, each of these cutting off 4 cells, with 2 proximal cells in the basipetal group each forming a descending cortical filament. Descending filaments lying parallel and forming a cortical layer over the axial cell, with longitudinally elongate cells that are mostly aligned in transverse rows.
Reproduction. Reproductive structures not observed.
Distribution. Known from tropical regions of the Indo-Pacific, its distribution includes the Great Barrier Reef.
