Marsilea drummondii
Also called Common Nardoo
Marsilea drummondii is a species of fern known by the common name nardoo (Diyari: ngardu). It is native to Australia, where it is widespread and common, particularly in inland regions. It is a rhizomatous perennial aquatic fern that roots in mud substrates and produces herbage that floats on the surface of quiet water bodies. It occurs in water up to one metre deep. It occurs in abundance after floods. It can form mats on the water's surface and cover the ground in carpets as floodwaters recede. It is variable in appearance and occurs in many types of wetland habitat. In general the frond is made up of two pairs of leaflets and is borne erect when not floating.
The plant produces sporocarps which can remain viable for 50 years and only release spores after being thoroughly soaked. These are dispersed by birds that eat them but cannot digest them, and by flowing water.
