life of this species of Calamus; but at the termination of this geological structure, it most probably ceases to exist.  A dioecious palm of low stature, and in habit similar to Seaforthia, was detected in the shaded forests investing the River Hastings, in latitude 31 degrees South, bearing male flowers; but as it may prove to be a dwarf state of a species of that genus, which has lately been observed, with all its tropical habits, in a higher latitude, it cannot now be recognised as a sixth individual of the family whose fructification has been seen.

Although this order has been observed to be sparingly scattered along the line of East Coast almost to the thirty-fifth degree of south latitude, its range on the opposite shores of the continent is very limited.  Upon the North-west Coast, the genus Livistona alone has been remarked, in about latitude 15 degrees South; beyond which, throughout a very extensive line of depressed shore, towards the North-west Cape, no palms were seen.  If the structure of a coast, and its natural disposition to produce either humidity or drought be consulted (a point, with respect to this order, as well as certain other tropical tribes, appearing very important) those portions of the western shores recently seen, indicate no one character that would justify the supposition of the existence of the Palmae in the corresponding extremes of the respective parallels that produce them on the opposite or East Coast.  Another remark relative to the economy of this family is, that in New Holland it seems confined to the coasts, Corypha australis, so frequent in particular shaded situations in the neighbourhood of Port Jackson, having never been detected in the vicinity of, or upon the mountains, much less in the distant country to the westward of that extensive boundary.

ASPHODELEAE.  Among the several described plants in the Herbarium, referred to this family, that were collected upon the East and South-west Coasts, are specimens in complete fructification of a remarkable plant of arborescent growth, having a caudex twenty feet high, and all the habits of Dracaena.  It probably constitutes a new genus distinct from Cordyline of Commerson, to which, however, it appears closely allied; and has an extensive range on the East Coast, where, although it has for the most part been observed within the tropic, it extends nevertheless as far as latitude 31 degrees South.  The only plants of Asphodeleae remarked on the north-western shores, were an imperfect Tricoryne, probably Tenella of Mr. Brown, discovered by that gentleman during the Investigator’s voyage on the South Coast; and the intratropical Asparagus, which is frequent in latitude fifteen degrees South.
