توصيف مختصر ريخت شناسي

Colonies with monosiphonic stems up to 2.5 cm high, arising from stolonal hydrorhiza. Branching irregular and in several planes. Branches originating laterally at hydrothecal base; plane formed by hydrothecae of lower-order branch perpendicular to that formed by hydrothecae of previous branch. Occasionally branches becoming anastomosing stolons distally. Stems divided into more or less straight internodes with oblique nodes sloping in alternate directions; one hydrotheca per internode. Hydrothecae abcaudally directed, with indistinct inflexion point where the adcauline wall becomes free. Adcauline hydrothecal wall adnate to internode for approximately half its length, though usually adnate part slightly longer than free portion. Free part of adcauline hydrothecal wall straight or slightly convex. Abcauline hydrothecal wall slightly concave. Cusps of hydrothecal aperture sharp and separated by deep embayments. Rim of hydrothecal aperture with frequent renovations. Gonothecae ovoid, inserting at hydrothecal base. Gonothecal walls spirally folded, forming a frill with eight or nine turns. Gonotheca distally with a long, funnel-shaped neck bearing the gonothecal aperture.
