Plant description

Rhizome sometimes woody herb, densely hairy when young. Fronds solitary or in clusters at nodes on a long stalk to 30 cm with four equally arranged leaflets, broadly obovate, to 30 mm long, both surfaces densely hairy or, when aquatic, almost glabrous, grey-green, entire or shallowly to deeply crenate. This species is very similar to Marsilea hirsuta, which differ by having larger sporocarps on very long stalks and more hairy leaves. Fruits are orange-brown oblong-ellipsoid pod (sporocarp), to 9 mm long and 3 mm wided, smooth to slightly ribbed covered in dense hairs on a stalk longer than the pod. Seeds are fine spores.
