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. CONIFERAE. To the general observations already made on that part of Coniferae inhabiting the southern hemisphere, may be added some important facts, to be gathered from the plants in the Herbarium of the late voyages, that will afford a very correct view of the fructification of some doubtful genera, as well as their limits. Among these the fruit of Podocarpus aspleniifolia of M. Labillardiere, was observed, together with the female fructification of another tree (the Huon pine) found also at the southern extremes and western coast of Van Diemen's Land, which may prove to be a Dacrydium. Callitris, of which seven species are known, and principally found in the parallel of Port Jackson, has also been discovered upon the North-west Coast, in about latitude 15 degrees South; and another species, remarkable for its general robust habit, was observed at Rottnest Island, on the West Coast. A tree, most certainly of this family, and probably (from habit) a Podocarpus, has been seen upon the East Coast, within the tropic, but the absence of fructification prevented its genus being satisfactorily determined. With respect to the extent of the order in the Islands of New Zealand, some recent specimens gathered upon the northern, prove one of its pines to be a Podocarpus; and another, producing a cone, and solitary, alternate scattered elliptical leaves, shows its relation to Agathis of Salisbury, or Dammar pine of Amboina. URTICEAE, whose mass appears also to be confined to equinoctial countries, may be considered very limited in those parts of Terra Australis lying within the tropic recently explored. Ficus is the most considerable genus of the order in that continent; and although chiefly found on the north and north-western shores, is also traced on the East Coast, almost to latitude 36 degrees South, where the trees attain an enormous size. About sixteen species are preserved in the collections of the late voyages; all small trees, and one half of which has been gathered on the North-west Coast.
