Description

Dendroid (bushy) colonial corallum. Main branch is not obvious. Extra-tentacular budding occurs near the base of old corallites. Colony size ranges from 10 mm to 20 mm in length and width and 10–15 mm in height. Corallite circular to slightly oval with a diameter ranging from 6.8–8.4 mm. Septal order is hexameral and in four cycles. Septal size, in a descending order, is S 15 S 2.S 35 S 4. S 3 and S 4 are weakly developed. Columella is deep, thin and spongy. Living colonies are pink and orange.
