Marsilea nardu.

Botanical name: 

Marsilea nardu A. B. Marsileaceae. Nardoo. Nardu.

Australia. The spores and spore cases of this plant are used by the aborigines for food, pounded up and baked into bread and also made into a porridge. These preparations furnish a nutritious food, by no means unwholesome, and one free from unpleasant taste but affording sorry fare for civilized man.
