spiny point, one-third the length of the scale. Seeds flattened 

 and appearing as if concealed within the scales, which they 

 resemble. 



A large tree, growing from 100 to 130 feet high, and 14 or 

 15 feet in girt, with a clear stem 80 feet high, and a rather thin,

 Australia. 



There are the following varieties :

Syn. Araucaria glauca, Loddiges. 



This differs from the species in nothing except in the glaucous

Araucaria Cunninghamii longifolia, Antoine. 



This variety has much longer and straighter leaves than the

Pine. 



Syn. Dombeya excelsa, Lambert. 

 Eutassa heterophylla, Salisbury. 

 Eutacta excelsa, Link. 

 Colymbea excelsa, Sprengel. 

 Altingia excelsa, Loudon. 



Leaves unequally awl-shaped, compressed, somewhat four-

 bent inwards, and pointless, from half to three-quarters of an 

 inch long, thick, three-edged, and recurved towards the branches. 

 Branches regularly verticillate, spread out straight, or curved 

 upwards at the extremities ; lateral ones opposite or alternate, 

 horizontal, or drooping, very closely placed along the sides in
