Naturalisation in Extra-Tropical Countries. 51 



Except a few palms (Mauritia, Attalea, Copernicia), this seems the 

 only tree, which in Tropical South- America forms forests by itself 

 [Martins], 



Araucaria Cookii, R. Brown. 



New Caledonia and New Hebrides. Height of tree to 200 feet. 

 Technical value similar to that of A. excelsa, habit more columnar. 

 Growth at Port Phillip not quite 30 feet in 20 years. The seeds 

 sometimes commence to germinate before dropping out of the cone. 



Araucaria Cunningham!, Aiton.* 



" Moreton-Bay Pine." Eastern Australia, between 14 and 32 

 south latitude, extending also to the highlands of New Guinea. The 

 tree attains a height of 200 feet, with a trunk 6 feet in diameter. 

 Growth in height at Port Phillip 30 to 40 feet in 20 years. The 

 timber is fine-drained, strong and durable, if not exposed to alternately 

 dry and wet influences ; it is susceptible of a high polish, and thus 

 competes with satin-wood, and in some respects with birdseye-maple. 

 Value in Brisbane, 2 15s. to 3 10s. per 1,000 superficial feet. The 

 tree grows on alluvial banks as well as on rugged mountains, over- 

 topping all other trees. The resin, which exudes from it, has almost 

 the transparency and whiteness of crystal, and is often pendent in 

 the shape of icicles, which are sometimes 3 feet long and 6 to 12 

 inches broad [W. Hill]. Araucarias should be planted by the million 

 in fever-regions of tropical countries for hygienic purposes, on account 

 of their antiseptic exhalations. 



Araucaria excelsa, R. Brown.* 



" Norfolk-Island Pine." A magnificent tree of unsurpassed sym- 

 metry, sometimes 220 feet high, with a stem attaining 10 feet in 

 diameter, and with regular tiers of absolutely horizontal branches, 

 one for each year. The timber is useful for ship-building and many 

 other purposes. Growth in height at Port Phillip about 40 feet in 

 20 years. With A. Cunninghami amenable to almost any soil, except 

 a saline one, and not subject to any disease. Endures also the vicis- 

 situdes of the clime of Lower Egypt. Resists sea-breezes to a 

 remarkable degree. Ceases to be hardy in the south of New Zealand. 



Araucaria imbricata, Pavon.* 



Chili and Patagonia. The male tree attains generally a lesser 

 height than the female, which reaches 1 50 feet. At Brest it attained 

 72 feet in 55 years [de Kersanton]. This species furnishes a hard 

 and durable timber, as well as an abundance of edible seeds, which 

 constitute a main-article of food of the natives. Eighteen good trees 

 will yield enough of vegetable food for a man's sustenance all the 

 year round. The wood is yellowish-white, full of beautiful streaks, 

 capable of being polished and worked with facility. It is admirably
