A, hydrocladial branching and disposition of hydrothecae; B–C, cauline apophysis showing axillary nematophores and ‘mamelons’ (note the presence of much-reduced nematothecae in B); D– E, unforked hydrocladial internodes (D frontal view, E lateral view); F–G, detail of mesial inferior nematotheca (F lateral view, G frontal view); H, gonotheca.
