No. 1. Arauoaria Bidwilli, Hooker yMx. Bidwill's Araucaria. 



Leaves, ovate, lanceolate, rigid, flat, deep-green, shining, and 

 spiny pointed, generally forming two rows along the branchlets, 

 and without any footstalks, narrower, and nearly two inches 

 long on the young plants, but much shorter and broader on the 

 more mature plants, and not more than three-quarters of an 

 inch long ; those on the stem alternate, those on the branchlets 

 somewhat two rowed. Branches, in regular whorls, from 5 to T in 

 number, but frequently more on the adult trees ; horizontal, those 

 near the base sometimes deflected, and not more than 12 feet 

 in length on old trees. Branchlets, in opposite pairs, about 18 

 inches long, slender, and rather thinly covered with flat, distant 

 sharp-pointed leaves. Cones, ovate-globular, or oblong, about 

 9 inches long, and sometimes nearly as broad, a little depressed 

 at the ends. Scales, large, projecting, with an acute transverse 

 ridge across the centre, highest in the middle, and furnished 

 with a sharp-pointed, reclining hook at the extremity, from 1 to 

 2 inches broad, and from half to three-quarters of an inch thick, 

 loosely adhering, and very deciduous when the seeds are ripe. 

 Seeds, very large, from 2 to 2| inches long, by three-quarters 

 of an inch broad, terminating at the apex in a short callous 

 marginal wing, furnished with a long, flat, tapering, curved 

 point, more than an inch long. Nuts eaten by the Aborigines. 



A majestic tree, with a very straight cylindrical trunk, grow- 

 ing from 100 to 150 feet. 



It is found on the Brisbane Mountains, and in the neighbour- 

 hood of Moreton Bay, in Australia. Mr. Bidwill, after whom it 

 was named, describes it as overtopping the forests, with a clear, 

 smooth, blackish trunk, and depressed, loose, conical head, and 

 that the timber is very fine, close-grained, and very durable. 



It is the ' Banza-tunza' or * Banya-tunya' of the natives. 



It is not hardy.
