) erect, bushy and densely branching; initially tufted, comprising stolons attached to a substratum, from which erect stems arise at intervals. As colonies grow, cross connections can occur so that the lower half of a colony tends to appear as a tangle, with branching in all planes. Colonies anchored by rhizoid-like stolons adherent to the substratum, becoming thick-walled with age. Tips of branches can also adhere to the substratum, continuing as adherent stolons, producing, at intervals, 5 opposing pairs of non-connate autozooids, each autozooid at an oblique angle to the stolon and somewhat flattened against the substratum, the whole cluster appearing overall like a pinna (
