Physical Description

Morphology

Colonies slender, stiff, sparsely branched, hydrorhiza creeping, growth monopodial with terminal hydranth. Stem stiff, upright, basally polysiphonic but largely monosiphonic; branching irregular, more or less in one plane, pedicels alternate, long. Perisarc thick, yellowish, thinning out distally, terminating at bases of hydranths. Annulations present at base of pedicels and branches, occasionally elsewhere but perisarc mostly smooth. Hydranths about 500 ?m long, urn-shaped, with large, flared hypostome. Tentacles filiform, numbering about 20. Gonophores fixed sporosacs. Male gonophores with one or two chambers, attached to non-reduced hydranths. Female gonophores undescribed. Nematocysts: macrobasic euryteles 12.9-14.1 x 5.5-6.4 ?m; heterotrichous microbasic euryteles 7.5-8.4 x 3.9-4.6 ?m.
