Araucaria Cunninghamii Ait. 
Richmond River or Hoop Pine. 
Araucaria Cunninghamii is a pyramidal tree with a somewhat 
flattened crown and attains a height of one hundred fifty to two 
hundred feet in its native land, the north coast district of New South 
Wales and the southern coast of Queensland ; it is one of the tallest 
Australian pines. The bark of this tree is quite characteristic, hav- 
ing the appearance of horizontal bands, whence it derived its name 
Hoop Pine. The leaves are of two different kinds; they are crowded 
and spirally arranged, prickly, and only about one-third of an inch 
long, while on the lower branches they are spreading, vertical, and 
often more than an inch in length. 
The male amenta or catkins are cylindrical and two to three 
inches long. The cones are egg-shaped and about four inches long 
and three inches wide. The wood of this pine is very valuable and 
is largely used for furniture; it is whitish in color and has often 
beautifully grained markings. Owing to its inability to stand ex- 
posure it is valued mainly for indoor work, and is extensively used 
for flooring and lining boards. The bark contains an oleo-resin and 
gum which have not yet been used commercially. The aboriginal 
name of this pine is Coarong, while besides the above mentioned 
vernacular names it is known in Australia also as Moreton Bay 
Pine, and Colonial Pine. 
Araucaria Cookii R. Br. 
This species, which was named for Captain Cook, the great cir- 
cumnavigator, is a native of New Caledonia and Isle of Pines off the 
coast of New Caledonia. 
It is similar in habit to Araucaria excelsa, but the lower branches 
tend to fall off. The leaves are alternate and rather distant, broad 
and slightly decurrent — that is, they have a tendency to run down 
the stem ; the old leaves are densely imbricated or overlap as the 
tiles of a roof, they are short, egg-shaped and not pointed. 
In its native habitat the tree reaches a height of often two hun- 
dred feet with a perfectly straight shaft.
