Minor branches subdivided dichotomously, up to fourth order, with the first branch internode 20-30 mm long. Branching sequence 1/3R in two large branches and 2/5R in the basal stem. Polyps 2-4 mm tall with a thin neck. Sclerites of polyp body of large and thick rods and spindles with many warts. Small scales and rods in tentacles with many warts. Scales in coenenchyme elongate with irregular edges and a few warts.
