Colonies with unbranched stems. Main cauline tube divided into single hydrothecate internodes with two or three infrathecal nematothecae at different levels; cauline apophyses with one nematotheca. Hydrodadia strongly branched (hydrocladia up to seventh order reported). Normally, primary hydrocladium giving rise to secondary hydrocladia in its first, fourth and eighth internodes; secondary hydrocladium also giving third-order hydrocladia in its first, fourth and eighth internodes; first tertiary hydrocladium giving rise to fourth-order hydrocladia in its first and fifth internodes; finally, fifth-, sixth- and seventh-order hydrocladia forming from the first internodes of previous series. Hydrocladia divided into single hydrothecate internodes. Unforked hydrocladial internodes with a single infrathecal nematotheca. Hydrotheca low. Forked hydrocladial internodes with two or three infrathecal nematothecae at different levels; hydrocladial apophyses with one nematotheca. Gonothecae sickle-shaped.
