The following plants, formerly considered as indigenous only in Van Diemen’s Land, have been recently ascertained to exist also in New South Wales, in or about the parallel of the colony of Port Jackson.

Croton viscosum, Labill., originally discovered on the South-west Coast, was seen in the interior, as far to the westward of the colony as longitude 146 degrees East.

Croton quadripartitum, Labill., was observed in longitude 148 degrees.

Goodia latifolia, Salisb., was remarked sparingly in the interior, in the meridian of 147 degrees 30 minutes East:  and Daviesia latifolia of Mr. Brown is very frequent in societies upon plains at Bathurst, in longitude 149 degrees East, where also Eryngium vesiculosum, of Labillardiere, was observed.

Aster argophyllus and obovatus, Labill.  These two species were described by Mons. Labillardiere, from specimens gathered in the southern extremes of the above island, and have been lately seen tolerably frequent in a remarkable tract of country, in latitude 34 degrees, on the limit of the colony, where the former assumes a robust, arborescent habit.  Aster phlogopappus, of the same eminent author, was recently remarked upon the more elevated parts of the Blue Mountain Range, on the margin of a remarkable cataract.

Should the botany of the shores of the Gulf of Carpentaria, in the vicinity of those parts, through which the above parallels pass, generally correspond (on comparison) with the above list, it is more than probable that these several species occupy portions of the intermediate interior bounded by the meridians of 125 and 145 degrees East; those plants excepted, having an asterisk prefixed to them, which as forming mangroves, or from other causes exist only on the sea shore.
