tions it becomes clear that the forest of Banks Apre is sufficiently 
characteristic to be regarded as a separate Afer is so considered 
by Cockayne in his Vegetation of New Zealand (p. 1 
At present, however, owing to the almost en c destruction of the 
original plant covering by , and in other ways, it is difficult to find means 
for reconstructing in imagination the original plant ае For- 
s Valley there is still a remnant of the primitive forest 
left on the valley-floor, through which neither fire nor sawmill has been, 
though, unfortunately, stock have run in it ; and there is also a portion of 
the same forest at the " pend of the valley ies an altitude of 1,500 ft. and 
upwards. know of no other place on the peninsula where fragments 
a the lowland and upland forest are left in a state of such good preservation 
n the same valley. This enables us to confirm more definitely certain 
conclusions regarding the forest, arrived > кае before. 
m this area it appears that the large trees on the valley-floors of the 
пееш were chiefly black and white pine with а comparatively small 
admixture of totara. As the valley narrowed the black and white pines 
were replaced by totara, which constituted the chief timber-tree E the 
Ilsides. Above 1,500 ft. Podocarpus totara became rarer, and plants of 
P. Hallii appeared, and soon predominated. At the same altitude seasonal 
plants of Libocedrus were to be found, In the valley referred to there 
a great break, however, in the forest between about 200 ft. and 1,000 ft., 
where now nothing but second growth occurs, so that the changes cannot 
be followed in deta il. 
In the lower forest there is a great variety of shrubs, including such 
plants already mentioned as are etsewhere rare in company—Teucridium, 
Pseudo eroz, Nothopanaz anomalum, Melicytus micranthus. Several 
specimens of eria fragrantissima were observed at a somewhat higher 
altitude. Pseudopanaz ferox is replaced by P. crassifolium below 1,000 ft., 
and Rubus australis becomes much more abundant, while the huge lianes 
be R. cissoides are no longer to be seen. The point where the kahikatea 
originally passed out of the forest cannot now be determined, but probably 
it was below 1,000 ft. Above this the forest takes on the ‘characteristics 
of the totara association described in the previous paper.
