Hydrorhiza a mat of stolons running along axis of gorgonian, bunching together at base of colony then passing upwards to become fascicular tubes of stem. Polysiphonic stems stiff, sparingly subalternately branched, primary branches widely spaced, occasionally secondary subdichotomous branching, one or two polysiphonic tubes running halfway to two thirds along branch or hydrocladium; branch and hydrocladia thereafter monosiphonic; a hydrotheca in axil of each branch. Hydrocladial internodes long, slender, perisarc moderately thick, smooth, nodes merely transverse constrictions, distinct when present, but often absent. Hydrothecae alternate to subalternate, widely spaced, facing frontally, 1 or 2 on internode, if one, about halfway to two-thirds up internode, if 2, one just below and the other just above node. Hydrocladial apophyses short, distal node transverse, deep.

Branches are given off from just inside the peripheral tubes of the stem. Hydrothecae in the axils of branches usually have long, undulated or regenerated pedicels. Hydrocladial nodes may be faint or altogether absent. As there is only one coppinia in the sample and the gonothecae are deeply embedded in the mass, sex could not be determined. Nematothecae are so numerous on the hydrorhizal stolons and peripheral tubes of the lower stem region that they impart a rough, prickly appearance to these structures.
