noctial parts of the continent. 
BiGNONiACEiE. — 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 cun- 
eated, 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 Bignoniacese appears to exist in 
the equinoctial parts of America ; some, however, are na- 
tives 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 con- 
tinent, the order exists only upon the North and East 
Coasts ; it is not, however, entirely limited to the tropic, for 
Tecoma of Mr. Brown is also found in latitude 34° South, 
on which parallel it has been traced at least three hundred 
and fifty miles in the interior to the westward of the colony 
of Port Jackson. 
Asclepiade.®, and Apocinea:. — Nearly the whole of the 
plants in the recently formed herbarium, that belong to these 
natural families, have been described from specimens for- 
merly discovered upon the East and North Coasts, several 
of which appear to give a partial character to the vegetation 
of some parts of its Shores.
