Much Cassinia scrub at the present time is an indigenous-induced asso- 
ciation, its presence a sign of burning the tussock-grassland.. Where more 
than one species of Cassinia is present there is a polymorphic collection of 
individuals impossible to classify in the present state of knowledge. 
ı8. Page 224. Rock associations of the dry mountains. 
The following species, some limited in their distribution, may be added 
to the species already given: Trisetum subspicatum, T. Cheesemanii, Luzula 
pumila, L. campestris (one or other of the vars.), Griselimia littoralis, Corokia 
Cotoneaster, Anisotome aromatica var., Pimelea aridula, Coprosma cunealta, 
Epilobium pubens, Veronica Traversit, Dias cymbifolia, Helichrysum pauci- 
florum (obligate rock-plant), 77. depressum, H. glomeratum, Senecio Haastü. 
Where H. glomeratum and H. bellidioides occur in proximity, the hybrid 
H. Purdiei — until its discovery in the mountains by CHRISTENSEN a few 
‚ years ago supposed to be a coastal plant of most restricted distribution — will 
usually be present. 
19. Page 225. Rock vegetation of the wet mountains. 
On the range traversed by the Motueka-Takaka road at an altitude of 
about goo m there is a rock association living under strong xerophytic condi- 
tions notwithstanding the wet climate. The substratum consists of irregular 
masses of hard limestone, the general aspect being that of a ‚rock-garden 
planted with low shrubs, the white stones showing in abundance. Water never 
lies on the surface, but at once escapes through holes in the rock and is 
carried away by underground drainage. S 
There is an open association of shrubs, most more or less ae even De 
the dense, divaricating Corokia Cotoneaster having taken on that habit. 
following are some of the species: Asplenium T; Trichomanes in revices), Aste 
' montana, Nothofagus cliffortioides, Pittosporum divar Y
