ny of
India, and the equinoctial parts of South America. Fourteen species of
Hibiscus and Sida were observed on the intratropical Coasts of Australia,
beyond which also, on the opposite shores of the continent, each genus
has been remarked. One species of Bombax with polyandrous flowers, and
subspherical obtusely pentagonal capsules, was discovered upon the East
Coast, in about latitude 14 degrees South, and on nearly the western
extreme of the same parallel, it appeared much more abundant. Of
Sterculia which is scarcely to be found beyond the tropics in other
countries, a species exists in New South Wales in the latitude of 34
degrees, on which parallel it is more frequent in the western interior,
and in that direction it has been traced to the distance of three hundred
miles from the sea-coast. The genus is also found on the North and
North-west Coasts, where the species assume more particularly the habits
of their congeners in India. Among the plants of this family in the
Herbarium is a species of Helicteris (as the genus stands at present)
which was observed on the North-west Coast bearing fruit, wanting the
contortion that characterizes the genus.

This plant, together with three other described species, having straight
capsules, may hereafter be separated from that Linnean genus, and
constitute a new one of themselves. Grewia, Corchorus, Triumfetta, and
Waltheria, have been observed upon the North-west Coast, where also
Abroma, hitherto limited to the tropical parts of New South Wales, has
been discovered bearing flowers and young fruit. One species of
Commersonia was gathered at widely-different parts of the north-western
shores, and Lasiopetalum, whose species are more general at both extremes
of the parallel of the colony of Port Jackson, has been also seen just
within the tropic on the East Coast, and at Dirk Hartog's Island, off
Shark's Bay, on the opposite shore.

CAPPARIDES. At least ten species of Capparis have been discovered upon
the coasts of Terra Australis, for the most part within the tropic, but
of these the fructification of two are wanting. A few have been detected
on the East Coast, but they are more frequent and various in their
species upon the north-western shores of the continent. Within an area on
this extensive coast, not exceeding four degrees of longitude, on the
parallel of 15 degrees South, a tree of very remarkable growth and habit,
has been traced, having all the external form and bu
