92 Mr. Brown, on the Proteacee of Jussieu. 
feature in the vegetation of the country, and contains a far 
greater number of species than on the east:—and in that part of 
the south coast, which was first examined by captain Flinders, it 
seems to be more scanty than at either of the extremes. 
On the west coast also, the species upon the wholeare more simi- 
lar to those of Africa than on the east, where they bear a somewhat 
greater resemblance to the American portion of the order. 
From the parallel of the mass, the order diminishes in both 
directions; but the diminution towards the north is probably 
more rapid on the east than on the west coast. 
Within the tropic, on the east coast, no genera have hitherto 
been observed, which are not also found beyond it; unless that 
section of Grevillea, which I have called Cycloptere, be considered 
asa genus. Whereas at the southern limit of the order several 
genera make their appearance, which do not occur in its chicf 
parallel. üesibun: ? QEON 
. The most numerous genera are also the most widely diffused. 
Thus Grevillea, Hakea, Banksia, and Persoonia, extensive in 
species in the order in which they are here mentioned, are spread 
nearly in the same proportion; and they are likewise the only 
genera that have as yet been observed within the tropic. - 
Of such of the remaining genera, as consist of several species, 
some, as Isopogon, Petrophila, Conospermum, and Lambertia, are 
found in every part of the principal. parallel, but bardly exist 
beyond it. Others, as Josephia and. Synaphea, equally limited 
to this parallel, have been observed only towards its western ex- 
tremity ; while Embothrium (comprehending for the present un- 
der this name all the many-seeded plants of the order), which is 
chiefly found on. the east coast, and makes very little progress 
towards the west, advances to the utmost limit of south latitude, 
and there ascends to the summits of the highest mountains. _
