thick, both heavily fascicled, polysiphonic tubes almost linear, sometimes a little twisted in lower stem region then running up branches; distal region of some branches with 2 or more tubes, a few branches monosiphonic. Branches bent at various angles, becoming more or less straight distally; walls of ultimate branches smooth without nodes. Apical stolonisation occurring on several branches where a tube becomes free of branch, walls of free tubes contorted and undulated, sometimes rejoining branch.

An empty conical structure at the broken distal end of a branch may be a damaged gonotheca; the structure is transparent, adpressed to the branch with the wider end facing distally and is overgrown by several polysiphonic tubes; it could be an empty corophiid tube. The diaphragm at the puncta line of the hydrotheca may have a downwardly directed hydropore but because of its delicacy the actual structure could not be ascertained. The free stolons at the ends of several branches seem to have developed from hydrothecal pedicels which have reverted to polysiphonic tubes, growth then proceeding onward without development of a hydrotheca. The thin strands of tissue issuing from many hydrothecae may be collapsed protective sheaths of hydranths. Several hydrothecae have remnants of tissue adhering to the rim which could easily be mistaken for opercular fragments.
