Name derivation:
Marsila named after Count Luigi Ferdiando Masili (1658-1730), an Italian scholar and eminent natural scientist, whose name was Latinised as Marsilius. Drummondii named after James Drummond (1786-1863), a Scottish born botanist and naturalist who was the curator of the government gardens in Cork, Ireland and an early settler in Western Australia.
Distribution:
Found across South Australia except on the Nullarbor and Kangaroo Island, growing on wet mud and clay, in swamps, waterholes, shallow depressions and ephemeral streams. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in the other states.
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.
Fruit type:
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.
Seed type:
Fine spores.
