Ficus is the most considerable genus of the order in that continent; and although chiefly found on the north and north-western shores, is also traced on the East Coast, almost to latitude 36 degrees South, where the trees attain an enormous size.

About sixteen species are preserved in the collections of the late voyages; all small trees, and one half of which has been gathered on the North-west Coast.
A species of Morus, bearing small white fruit, was discovered upon the continent and islands of New South Wales within the tropic, where also a new genus of the order, with radiated leaves, has been traced as far as Endeavour River.

Of the genus Urtica, whose numerous species can simply be considered as of herbaceous duration, although a few of tropical existence assume a fruticose habit, there is one plant in the vicinity of the Colony of Port Jackson, remarkable for its gigantic, arborescent growth; many specimens having been remarked from fifteen to twenty feet in height, of proportional robust habit, and of highly stimulating nature.
SANTALACEAE.

Nearly three-fourths of the Australian portion of the order described, were formerly discovered in the parallel of Port Jackson, upon the shores of the South Coast, and in Van Diemen's Land.

The genus Choretrum, however, heretofore limited to the southern extremes of the continent, approaches within about two degrees of the tropic on the West Coast, having been lately observed on Dirk Hartog's Island.
