Grewia, Corchorus, Triumfetta, and Waltheria, have been observed upon the North-west Coast, where also Abroma, hitherto limited to the tropical parts of New South Wales, has been discovered bearing flowers and young fruit.

One species of Commersonia was gathered at widely-different parts of the north-western shores, and Lasiopetalum, whose species are more general at both extremes of the parallel of the colony of Port Jackson, has been also seen just within the tropic on the East Coast, and at Dirk Hartog's Island, off Shark's Bay, on the opposite shore.
CAPPARIDES.

At least ten species of Capparis have been discovered upon the coasts of Terra Australis, for the most part within the tropic, but of these the fructification of two are wanting.

A few have been detected on the East Coast, but they are more frequent and various in their species upon the north-western shores of the continent.

Within an area on this extensive coast, not exceeding four degrees of longitude, on the parallel of 15 degrees South, a tree of very remarkable growth and habit, has been traced, having all the external form and bulk of Adansonia of the western shores of Africa.
