Original description: 
“The corallum is ramose; and the smaller branches end 
suddenly with rounded tips* The whole is cohered with crowded 
irregular calices, separated by thin and sharp walls, without 
ornamentation* The calices are deep, often quadrangular or 
pentagonal; and the styloid columella is situated deeply, and is 
usually small. 
The septa are well developed. There are eight large ones, 
which reach the columella, and eight smaller, which project more 
or less, and are of different lengths in different calices, but 
which do not reach the axis*
