Minutely glandular decumbent, facultative amphibious herb with flowering stalks to 30 cm long and thin tap roots. Leaves two types, elliptic to 50 mm long and 10 mm wide on long extended stalk to 350 mm long when floating on the surface. In dried condition mostly basal, oblanceolate to spathulate to 60 mm long and 10 mm wide, tapering gradually into a stalk to 30 mm long, margin entire or with a few teeth, hairy. inflorescence in loose spreading terminal spike with elongated yellow (purple striation) fan-flowers. Flowering between June and October. Fruits are brown hairy ellipsoid capsule to 8 mm long with sepals attached about half way and splitting in two. Seeds are flat light brown ovoid seed to 0.8 mm long and 0.4 mm wide, with a smooth surface and clear wing around the outer edge. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between September and October. Collect capsules that are maturing, turning brown, easily split open and with brown seeds inside. Place the capsules in a tray and leave to dry for a week. Then rub the capsules with your hands to dislodge the seeds. Use a sieve to separate the unwanted material. Be careful as the seeds are very fine. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability is high, at 100%.
