Colony with unbranched stem. Main cauline tube with single hydrothecate internodes with four to six infrathecal nematothecae; cauline apophysis with one nematotheca. Hydrocladia up to third order. Hydrocladia heteromerously divided into internodes; with single and double hydrothecate internodes and with ahydrothecate internode, provided with two to four nematothecae, following cauline and hydrocladial apophyses. Single unforked hydrocladial internodes with two infrathecal nematothecae at different levels and one or two suprathecal nematothecae; double internodes with two infrathecal nematothecae at different levels under first hydrotheca, three between both hydrothecae, and one suprathecal nematotheca above second hydrotheca. Hydrotheca deep. Forked hydrocladial internodes with five to seven infrathecal nematothecae; hydrocladial apophyses with one nematotheca.
