In the present material cauline internodes are provided with three infrahydrothecal nematothecae and, sometimes, one suprahydrothecal nematotheca. Intermediate ahydrothecate internodes, following cauline and hydrocladial apophyses, are provided with two to three nematothecae. Unforked hydrocladial internodes with two to four infrahydrothecal nematothecae and one to two suprahydrothecal nematothecae. Double internodes with three nematothecae below first hydrotheca, three nematothecae between both hydrothecae and one nematotheca above second hydrotheca. As typical, hydrocladia very long, with up to 47 hydrothecae.
