The forest varies much according to its exposure to wind; in the grullien 
'trees are io m high, but, on the ridges, they are much smaller. The belt begins 
at an altitude of about 600 m and ends at 900 m as a minimum. At first, there 
is plenty of N. fusca; Podocarpus-Hallii and Weinmannia racemosa are present 
throughout, the latter often a shrub. Pittosporum rigidum occurs in the upper- 
most part with other subalpine-scrub plants.

of Pseudopanax lineare and in the colonies of Dracophyllum Traversii of its. 
upper portion. At 1020 m, N. Mensiesüi gives place to N. cliffortioides. 
The subalpine forest of Mt. Rochfort is a combination of N. Menziesü and 
N. cliffortioides associations, so ‚far as canopy-trees go, but its contents and ;
