and Alseuosmia quercifolia. Dicksonia lanata, but trunkless, ascends to 1080 m, 
or more, and may form much of the undergrowth, its fronds being 1.5 m long. 
Many of the lowland ferns are common and ZLepfopteris superba forms consi- 
derable colonies. At an altitude of 960 m (PHILLIPS TURNER 1909:3), Dacry- 
Ba cupressinum, hitherto abundant, becomes much scarcer and the forest is 
re typically subalpine with Bildnis Bidwillü dominant and Podocarpus 
Halli, Dacrydium Colensoi and D. intermedium abundant. Tussocks of Gahnia 
pauciflora become characteristic and the subalpine-scrub plants of the vicinity 
enter into the association. In some parts of this association, as where it abuts 
on the Waimarino Plain, near Horopito and elsewhere, the haste tuft-tree - 
EN indivisa is abundant.

At an elevation of about 850 m the character of the forest changes Br 
 Hallü becoming abundant, and other trees and shrubs not common below 
appearing in quantity e. g. — Coprosma tennifolia, Nothopanax Colensoi. At 
a somewhat higher altitude, Zidocedrus Bidwillii appears and soon becomes 
dominant, though Podocarpus Halli, Weinmannia racemosa and Griselimia litto- 
‚ralis are abundant‘). This latter is bent, arched and gnarled, while its trunk may be 
covered by sheets of the dark, curled leaves of Hymenophyllum sanguinolentum 
and yello' vish-gre 1 cushions of Dieranoloma Billardieri. The common shrubs
