Corallum arborescent; base creeping, relatively small, heavily epithecate. Common trunk low, 4.7 cm across. Branches heavy, angular; expanding, becoming palmate at levels of subdivision. One branch 3.2 cm across at base, 5.1 cm at level of subdivision; another branch has these corresponding dimensions: 3.9 cm at base, 6.3 cm at branching. Terminal branchlets up to 2.5 cm long, 1.8 cm across just below tip; not very markedly attenuate; apex well rounded, bearing several apical corallites. Surface very rough because of rosettes of corallites present here and there and also because of corallites lying in all directions. Oftentimes, apex of branchlet resembles rounded head, set off by slight constriction.
Axial corallites vertical, thick walled although some are thinner on one side; up to almost 4 mm diameter with calice 0.8 mm; crowded. Primaries reaching half radius points or beyond, crinkled; secondaries half as wide; 2 cycles complete.
Radial corallites very crowded except towards base where they are smaller and somewhat lax; tubular or tubonariform, all adnate (appressed) without any definite position so many overlapping in all directions; top well rounded; calices small, not occupying entire top. Corallites on upper region up to 4 mm long, 2.5-3 mm wide, many with enlarged bases, tapering; toward base they become lower, some becoming conical, again with small calices. Some small, less adnate corallites among bigger ones.
Primaries complete cycle reaching half radius circle or slightly beyond but varying thickness; usually appearing distorted, their edges crinkled or unequally cut. Directives slightly distinguishable. One or 2 secondaries present in some calices, very thin, narrow.
Walls of corallites covered with fin, crowded spinules of even height, reticulum obscured; spinules scarce on intercalicinal areas so reticulum visible. Spinules on calicinal wall in form of fimbriated, narrow platelets; those on intercalicinal areas not as clearly cut. The roughness of the general surface and the size and position of the radials are easily the most distinctive characteristics of this coral.
