Census of South Australian plants (external link)     [genus Marsilea]
Name derivation:
Marsila named after Count Luigi Ferdiando Masili (1658-1730), an Italian scholar and eminent natural scientist, whose name was Latinised as Marsilius. Hirsuta from the Latin 'hirsutus' meaning hairy; referring to the species being covered in hairs.
Distribution:
Found across South Australia except in the Nullarbor and Kangaroo Island, growing on drying mud in swamps, waterholes, shallow depressions and ephemeral streams. Also found in all mainland state
Status:
Native. Common in South Australia. Common in other states.
Plant description:
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.
Fruit type:
Brown bean-shaped pod (sporocarp) to 3mm long and 2 mm wide, slightly ribbed, densely hairy, on stalk shorter than the pod.
Seed type:
Fine spores.
