Complex colonies with up to four orders of branching; branches more or less alternate, usually in one plane, primary and subsequent branches often originating just above a hydrotheca, ultimate branches (hydrocladia) and some branches in lower stem region monosiphonic.

The larger colonies are rather flexuous and the ultimate monosiphonic branches are quite lax out of fluid. The long, curved hydrothecae are characteristic. The free part of the hydrotheca is tubular but the adnate adcauline hydrothecal wall narrows, becoming increasingly indefinite and rather fibrous in appearance as it passes downward into the hydrocladium.
