of these orders (which are admitted to
be very nearly allied to each other) seems in Australia to exist on its
eastern coast, within and beyond the tropic, and the species in the
collection lately formed, are referred to ten established genera, of
which (as belonging to Verbenaceae) Vitex and Premna are most remarkable
on the North-western Coast.

Of Labiatae, a new species of Labillardiere's genus Prostranthera was
discovered upon Dirk Hartog's Island, where, as also at Rottnest Island,
Westringia was observed, of species, however, common to the South Coast.

BORAGINEAE. Some very important amendments, in reference to the limits of
certain genera of the order have been proposed by Mr. Brown in his
Prodromus, where the characters are remodelled to the exclusion of
certain species previously referred to them by authors. Of Cordia (to
which Varronia of Linne, and Cerdana of Ruiz and Pavon, have at length
been united) only two species have been found in Terra Australis, of
which one had been previously discovered in New Caledonia; and during the
late voyages C. orientalis has been observed on the North-west Coast,
where a third species of Tournefortia in complete fructification was
discovered; and the Herbarium contains some species of that section of
Heliotropium, having a simple straight spicated inflorescence, which were
also found on those equinoctial parts of the continent.

BIGNONIACEAE. Almost ninety species of this beautiful order are described
by authors, the greater part of which are at present incorporated among
the genuine species of Bignonia of Linne; a genus that will hereafter be
divided, according to the shape of the calyx, the number of fertile
stamina, and more especially the form of the fruit (which in some species
is an orbicular or elliptical capsule, varying in others to a long
cylindrical figure, with seeds partly cuneated, or thickened at one
extremity, and in others, a truly compressed Siliqua) together with the
relative position of the dissepiment, in respect to the valves of the
fruit.

The greater portion of Bignoniaceae appears to exist in the equinoctial
parts of America; Some, however, are natives of India, and a few occur on
the western coast of Africa, and Island of Madagascar, but in Terra
Australis the order is reduced to four plants, of which one is a recent
discovery, and may be referred to Spathodea. In that continent, the order
exists only upon the North and East Coasts; it is not,
