Colonies are usually open branched, becoming bushy on upper reef slopes and in shallow lagoons. Main branches may have compact branchlets giving colonies a bushy appearance. Corallites are widely spaced and vary greatly in size, the largest being appressed and tubular. The coenosteum is fine, giving branches a smooth appearance.
