Fragment polysiphonic along basal part. Main tube segmented, with internodes separated by transverse nodes; each axial internode with two apophyses bearing hydrocladia, one in mid-region and another just under distal node, and two nematothecae, one just above basal node and another above first apophysis. Apophyses alternately directed right and left, arising only from main tube; each apophysis with one well-developed mamelon on upper surface, and with 3–4 nematothecae: two axillary and one or two distal to mamelon; one perisarcal ring occurring near node. Hydrocladia with proximalmost internode ahydrothecate, bearing one nematotheca on a small elevation towards base; perisarcal rings sometimes visible, with one basal and other distal; rest of hydrocladium comprising a succession of hydrothecate and ahydrothecate internodes. Hydrothecate internodes with one hydrotheca and three nematothecae: one mesial inferior and two laterals. Hydrotheca cup-shaped; adcauline wall fully adnate; abcauline wall straight; hydrothecal margin smooth, circular, perpendicular to hydrocladial axis. Mesial inferior nematotheca on a small elevation, reaching and sometimes surpassing hydrothecal base. Lateral nematothecae on a small apophysis placed below hydrothecal margin, extending well beyond orifice. Mesial and lateral nematothecae with a slightly scooped distal chamber. Number of perisarcal rings variable, with a maximum of six; on distal parts, rings may be absent or not visible. Ahydrothecate internodes with one nematotheca on basal part, arising from a small elevation; perisarcal thickenings two, with one at each end. All nematothecae bithalamic, movable. Nematothecae of apophyses larger than those of hydrocladial internodes.
