Corallum flat, fan-shaped, closely reticulate; growing obliquely from a base only 4.5 cm across and very short. Stems, branches and branchlets flattened, closely anastomosing. Most branches and branchlets grow along same plane, hence flattened appearance of corallum. Lower surface smooth except for very few incipient branches that fail to grow and very few, scattered corallites usually located at lines of fusion. Upper surface produces scattered tall tapering corallites standing vertically or almost so to the general surface, the older ones bearing radials. Stems and branches marked on their upper surface with distant low nariform or subimmersed corallites; on their lateral margin they produce abundant side branchlets which are closely anastomosing and growing on the same plane.

Prominent corallites on upper surface tapering cylinders, ranging from 4 mm to 10 mm high, 3-4.5 mm basal diameter, around 2 mm apical diameter; unevenly disposed, usually slightly curved; apex rounded; calice small, not occupying entire apical area; one may be designated as ramiculi with subimmersed radial; few with tall radials resembling axial. Lateral ramiculi flattened, also tapering before anastomosis, slightly wider than vertical ones.

Septa in both axial and radial corallites usually 6 with one or both directives distinguishable, lamellate, thin, broad. Rarely some secondaries present but cycle incomplete.

Intercalicinal areas and calicular wall covered with trim, even spines resembling tiny plates (flakes) standing on edges, crowded. Pores visible on younger portions, slits or cracks on older.

Remarks:This coral can be distinguished by its distant corallites on the lower areas, its method of branching and its complete covering of fine, even spines.
