? ialtorese?m?a, which were ?lso fo?md On tho? equi- noctial parts of the continent. Bxo?o?x?c?.?.--Almost ninety species of this beautiful ?)rder are described by authors, the greater part of which are at present incorporated 'among the genuine species of Big'nonia of Linn?; 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 i n others to a long' cylindrical fig?re, with seeds partly cun- cared, 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 Bignoniacem 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- talent, 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 �th, on which parallel it has been traced at least three hundred and 6fty miles in the interior to the westward of the colony of Port Jackson. AscL?x.?n?.? and A?ocxs?.--Nearly the whole of the plan. ts in the recently formed herbarium, that belong to these ? natural families, have been described from specimens for- merly discovered Ul?On the East and North Coasts, several of which appear to give' a partial character to the vegetation of some parts of its Shores.
