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.
