Leaves long-stalked, broad lanceolate and rounded at the base (unlike Narrow-leaved Water-plantain or Lesser Water-Plantain where the leaves are narrower and gradually taper towards the water).

Flowers on long thin stalks. Flower stalks mostly in threes to sixes where they join thicker stems.

The flowers congregate near the ends. Each with three stubby sepals.

As with most aquatic plants, petals are in threes, lilac pink near the edges, whiter nearer the middle, but with a yellow splodge at the centre.

Light-green ovary in centre a bit like a toroidal ferrite core. This will become the fruit later.

Fruits have a toroidal appearance too un-like those of Lesser Water-Plantain which have a knobbly appearance like those of Buttercups. The three sepals are now spread flat out.

Leaves taper abruptly to join the leaf 'stem' which is thin but curved for stiffness. Leaves have fainter yellow veins and are all aerial with no other leaves underwater un-like Lesser Water-Plantain.


No relation to : Water-plantains are not related to plants such as Ribwort Plantain, Hoary Plantain, Greater Plantain, Sea Plantain or Buck's-horn Plantain [plants with similar name]

Not to be semantically confused with : Robin's Plantain (Erigeron pulchellus) which is a member of the Daisy & Dandelion Family (Asteraceae).

Hybridizes with Narrow-leaved Water-plantain to produce Alisma × rhicnocarpum.

Habitat is in and by fresh-water, although always likes to get its feet wet.
