t wholly exotic tribes, that form a prominent feature
in the Flora of other equinoctial countries, tend, in some measure, to
diminish the peculiar character of the vegetation of Terra Australis on
those shores, and thus it is a considerable assimilation to the Flora of
a part of a neighbouring continent that has been traced. About thirty
species are preserved in the collections of these voyages, for the most
part belonging to genera existing in India, but more abundant in the
tropical parts of South America.

Of these, Gardenia, Guettarda, Cephaelis, Coffea, Psychotria, and
Morinda, are found on the East Coast; whilst, in corresponding parallels
on the opposite, or north-western shores, the order, although not
materially reduced, is limited to the two latter genera, with Rondeletia,
Ixora, and Genipa.

It is worthy of remark, that the range of Psychotria, which has not been
observed beyond the tropics in other countries, extends in New South
Wales as far south as the latitude of 35 degrees; at the western
extremity of which it does not appear to exist.

CAPRIFOLIAE, Juss. The situation of Loranthus and Visvum, in the system,
appears to be undetermined by authors. M. Jussieu associated them with
Rhizophora, in the second section of this order, from which Mr. Brown has
separated this latter genus, and with two others found in Terra
Australis, has constructed a distinct family, named Rhizophoreae;
suggesting, at the same time, the analogy of Loranthus and Viscum to
Santalaceae, and particularly to Proteaceae. The genus Loranthus, of
which nearly the whole of its described species have been limited to the
tropics, is, however, sparingly scattered on all the Coasts of Australia,
where about eleven species have been recently observed, parasitical
chiefly upon certain trees that constitute the mass of the forests of
that vast continent; namely, Eucalyptus, Casuarina, Acacia, and
Melaleuca.

A solitary and very remarkable deviation from the usual natural economy
of Loranthus, is observed in a species (L. floribunda) described and
figured by M. Labillardiere, which is found on the shores of King
George's Sound, where, in no way recognising the dependent habits of its
congeners, it rises from the soil to a tree fifteen feet high, being
never remarked relying upon other vegetables for its subsistence. Viscum
is found in the colony of Port Jackson, to which it is not confined,
having been also gathered at Endeavour River, on th
