Short, but 3 inches tall. Grows in shallow water often overgrown by much larger plants.

The leaves carpet the ground hiding the wetness beneath.

The leaves are shiny, almost round with less than a dozen shallow lobes on the periphery. Stem in the centre.

Eight veins radiate from the centre, forking when half-way into several fractal branches.

Un-like the leaves of Floating Pennywort (which has almost circular leaves with the stalk in the centre but with a deep cut on one side to the supporting stem) the leaves of Marsh Pennywort are orbicular and peltate, with circular leaves, stem attached to the centre and without a deep cleft in the leaf to the stalk - although it does have slight nicks on the periphery). The flowers are hidden under a canopy of leaves.

Stems hairy with long white hairs, underside of leaf sparsely hairy - perhaps to aid the formation of drops of water to drip-dry the leaf since obviously, this not being of the floating variety, it might not like being perpetually wet underneath.


Some similarities to : Navelwort (the leaves only)

No relation to : Wall Pennywort [a plant with similar name]

Marsh Pennywort was previously ascribed to the Apiaceae family, but has since been moved into a family of its own, together with two other Pennyworts Floating Pennywort and Hairy Pennywort; but not Wall Pennywort, which is a totally different plant.
