Rhizome herb, hairy when young but beming glabrous. Fronds solitary or in clusters at nodes on a long stalk to 18 cm with four equally arranged leaflets, narrowly to broadly obovate, to 20 mm long, moderately hairy to almost glabrous when fully aquatic, outer margin rounded, entire or slightly crenate. This species is very similar to Marsilea drummond, which differ by having smaller sporocarps on very short stalks and usually less hairy leaves. Fruits are brown bean-shaped pod (sporocarp) to 3mm long and 2 mm wide, slightly ribbed, densely hairy, on stalk shorter than the pod. Seeds are fine spores.
