Description

Leaves with canaliculate petioles, blades lanceolate, narrowly to broadly ovate, sharp on the tip, decumbent or rarely abrupt on the base, 18 – 24 cm long x 2 – 9 cm wide, with terrestrial forms usually only 10 x 2 cm having 5 - 7 veins and distinct pellucid lines.

Stem below cylindrical, between whorls triangular in cross-section, often alate, 35 – 120 cm long. Inflorescence racemose or paniculate having 4 - 15 whorls. Bracts on base connate, longer than the pedicels (up to 3.5 cm). Pedicels 0.5 – 2 cm long. Sepals 4 – 6 mm long, petals about twice as long, the diameter of the corolla 1.2 - 1.5 cm. Usually 12 stamens, achenes 2 x 1.5 mm with one, rarely 2 glands separated by a rib. Stylar beak bent back - reaching usually 1/4 of the body.[2][3][4][5][6][7]

Vegetatively, resembles E. andrieuxii, nut differs by having distinct pellucid lines, a usually paniculate inflorescence and by achenes with beaks that are at most 1/3 as long as the body.

Cultivation

Deep, rich growing substrate and a good light. Will grow submersed or emersed. Benefits from additional CO2.[8]
