Nor are there any extensive families peculiar to these regions; the only characteristic tribes being that small section of aphyllous, or nearly aphyllous Cassiae, which I have particularly adverted to in my account of some of the species belonging to Captain Sturt’s collection; and several genera of Myoporinae, particularly Eremophila and Stenochilus.  Both these tribes appear to be confined to the interior, or to the two great gulfs of the South coast, which may be termed the outlets or direct continuation of the southern interior; several of the species observed at the head of Spencer’s Gulf, also existing in nearly the same meridian, several degrees to the northward.  It is not a little remarkable that nearly the same general character of vegetation appears to exist in the sterile islands of Dampier’s Archipelago, on the North-west coast, where even some of the species which probably exist through the whole of the southern interior are found; of these the most striking instances are, Clianthus Dampieri, and Jasminum lineare, and to establish this extensive range of these two species was my object in entering so minutely into their history in the preceding account.

A still greater reduction of the peculiarities of New Holland vegetation, takes place in the islands of the South coast.
