Material examined. 9778#1, a fragmented stem (largest fragment 160 mm long), no gonothecae. Description. Stem branched and polysiphonic, broken into several fragments; longest fragment, the basal one, with hydrorhiza and completely polysiphonic, c. 160 mm long. Branching more or less in one plane and mostly alternate. Lower-order stems polysiphonic in part of their extension; at least third-order stems present. Stem divided into internodes and with alternating verticils of three apophyses, giving rise to six longitudinal rows. Each cauline internode usually with a single whorl at distal end; double internodes with two verticils of apophyses also present. Apophyses supporting hydrocladia and provided with one mamelon and three pairs of nematothecae (Fig. 9F): one at base of apophysis, a second pair in the middle and a third one at distal part. Hydrocladia homomerously divided into ... : Published as part of Peña Cantero, Álvaro L. & Horton, Tammy, 2017, Benthic hydroids (Cnidaria, Hydrozoa) from bathyal and abyssal depths of the Northeast Atlantic held in the modern Discovery Collections, pp. 1-30 in Zootaxa 4347 (1) on page 23, DOI: 10.11646/zootaxa.4347.1.1, http://zenodo.org/record/1044772 ...
