Plate 2: Grass trees at Yankallillah, with the red kangaroo (Macropus Laniger - Gould). Part of the text accompanying the illustration reads 'This scene represents the largest variety of the Xantharea, which is to be met with in South Australia; there are from ten to fifteen species already known, all of which are designated by the Colonists as "grass trees" ... The kangaroo figured in the plate is the Great Red Kangaroo, the (Macropus laniger) of Gould; it is not frequent in South Australia, at least within the limits of the settled districts ...'.

Grass trees (Xanthorrhoea australis) are native to south-east Australia. Also known Kangaroo Tail, it has very long, thin, grass-like leaves that grow up to 3 feet in length. It takes 30 years or more for the leaf tuft to rise above the trunk.

The largest of the marsupials, the red kangaroo is probably one of the best known of the species and lives in small groups in the dry interior. The animals can go without water for a considerable time, provided there is green feed available. The males weigh up to 90 kilos and can be 2 metres tall. Contrary to their name they are not always red, but are greyish blue. They can travel at speeds of up to 60kms per hour and leap 8-10 metres. Yankallillah is the spelling used by Angas.
