The Chili and Brazil Pines have long been regarded as identically the same species; but a careful investigation
proves them to be essentially different. The Brazilian species is characterized by its more spreading and
branchy habit; by its loosely imbricated, longer, glaucous-green leaves, which are of a much thinner and more
flexible texture than those of A. imbricata and terminated by a less rigid point; and lastly, by the form of
its female amenta which are rounded-oval, with the scales terminated by a short, linear-lanceolate, acute, recurved
appendage or scale, and bearing each solitary ovula. Its quick and vigorous growth is also an important
characteristic mark. The Araucaria imbricata is, on the contrary, of remarkable slow growth, with
the leaves closely imbricated, very rigid, dark green on both sides, and of a thick coriaceous texture, cartilaginous
at the margins. The scales of the female amenta are terminated by a much longer, broad-lanceolate,
