distinct stamens, almost limited to the parallel of Port Jackson and
the South Coast, were observed: Daviesia, almost wholly restricted to the
higher Australian latitudes, has been remarked on the North Coast. Of
Lomentaceae, Bauhinia, Caesalpinia, and the emigrant genus Guilandina,
are all of intratropical existence in New South Wales, as also upon the
North-west Coast; but Cassia, although it has an equal extensive range in
the equinoctial parts of New Holland, has also been recently traced as
far in the interior, on the parallel of Port Jackson, as the meridian of
146 degrees East.

EUPHORBIACEAE. The Herbarium contains thirty-three plants of this very
numerous order, whose maximum seems decidedly to exist in India and
equinoctial America. The whole of the Australian species are referable to
established Linnean genera, of which Croton and Phyllanthus are most
remarkable and numerous, existing on all the intratropical shores of
Terra Australis, but by no means limited to them, both genera, together
with Euphorbia and Jatropha, being found in the parallel of Port Jackson;
and Croton exists likewise at the southern extreme of Van Diemen's Land,
which is probably the limit of the genus on that hemisphere.

A Tragia (scarcely distinct from a species indigenous in India) is
sparingly scattered on the East and North Coasts; and Acalypha has been
remarked on these, as well as the north-western shores.

PITTOSPOREAE. Of this small family, whose characters and limits were
first described by Mr. Brown, there are sixteen species in the Herbarium
of these voyages, referable to Bursaria, Billardiera, Pittosporum, and
two unpublished genera.

Billardiera, whose species are wholly volubilous, and which are not found
north of the parallel of Port Jackson, is frequent on the South-west
Coast, and has been recently remarked on the West Coast of Van Diemen's
Land. Bursaria on the other hand, appearing limited to New South Wales,
has been traced within the tropic to latitude 19 degrees South on those
eastern shores, and although the genus Pittosporum is even more
extensively diffused on that coast, it has not been met with upon the
north-western shores, whilst the islands off the West Coast furnished me
with two new species.

DIOSMEAE, although very frequent in the higher latitudes of Terra
Australis, where they are so frequent as to give a peculiar character to
their vegetable productions, is comparatively rare within the tropic; f
