Color: Colony dark red, spicules pink.

Specimens with planar non-reticulate morphology. Stalk with button-shaped holdfast; diameter of stalk 3 mm and denuded off soft parts. Main branch formed as the continuation of the stalk and the branchlets given off divide and redivide forming the expanse of the colony. The ultimate branches formed have a diameter of 1 mm (excluding calyces). Calyces arranged laterally along the branches and branchlets; at places 3 to 4 calyces may be seen crowded together and arranged on all sides; terminal part of the branchlets often blunt but sometimes two calyces may be seen arranged in a divergent manner. Average size of calyce 1 x 0.75 mm (diameter x height), sides strongly sloped and as the calyces are arranged at an angle to the axis, the side facing the axis is shorter than the other side. Polyps retractile fully, axis pale brown and flexible.
Spicules: (1) Echinogorgia type. Foliaceous with basal part forming 2 to 3 root-like structures.
