The isolated osiekan of the mountain 1200 m high and its geographical 
situation render it of peculiar interest. For what follows I am indebted to 
. E. PHitLıps TURNER and Major A. A. DORRIEN SMITH. On the summit 
of the mountain there is a small expanse of herb-field the chief members of which 
are: — Danthonia Raoulii, Poa Colensoi, Phormium Cookianum, Astelia mon- 
tana, Chrysobactron. Bibokini Kanunculus gerantifolius,; Acipyylla Colensoi,

It would be en beeihie, even were anything like exact details available, 
to put forth in a short general account of the association the relationship “ 
between the dominance of this or that plant to soil or topographical conditions. 
Suffice it to say, that in some places tussocks dominate, in others Phre 
Cookianum and again, in others, species of Celmisia or Ranunculus. 
' The tussocks consist of Dariekiinid favescens, D. crassiuscula, D. Cunning- 
hamii and D. Raoulii, the latter the most uncommon. The tussocks of D, 
Cunninghamii are 1.5 m high at times, the leaves flat, 7 mm broad and the 
large panicle very handsome. D, crassiuscula often for an association on
