RuBiACEiE. — The existence of several plants of this ex- 
tensive family in the intratropical parts of Terra Australis, 
especially when aided by some individuals of almost wholly 
exotic tribes, that form a prominent feature in the Flora of 
other equinoctial countries, tend, in some measure, to di- 
minish 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 con- 
tinent that has been traced. About thirty species are pre- 
served 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, Psycho- 
tria, 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 li- 
mited 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° ; at the western extremity of which it does 
not appear to exist. 
CAPRiFOLiiE, Juss . — The situation of Loranthus and Vis- 
vum, in the system, appears to be undetermined by au- 
thors. 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 
Rhizophorese ; suggesting, at the same time, the analogy 
of Loranthus and Viscum to Santalacese, and particularly to
