334 Appendix. 
The belt is a narrow, stony tract, consisting of peridotite and serpentine 
rocks, extending for about 96 km from D’Urville Island to Nelson with its 
widest part (about 5 km) in the vicinity of the Dun mountain. The vegetation 
of the belt both in its density, its associations and its growth-forms presents 
a striking contrast to that of the adjacent luxuriant Norkofagus forest. The 
transition from forest to Mineral belt vegetation is hardly to be seen, each . 
standing out distinct. Not only does the Magnesian soil influence the asso- 
ciations but it changes the growth-forms, so that trees beyond its influence 
are merely shrubs on the belt (the spp. of Norhofagus, Griselinia lıttoralis). 
The associations of the belt consist of shrubland, fell-field and tall tussock- 
grassland, the latter with a small variety of Danthonia flavescens dominant. 
Taking the species of shrubland and fell-field together, for these associations 
merge into one another, the following are the more important: Phyllocladus 
alpinus, Poa sp. (related to P. acicularifolia), Festuca sp. (unnamed), Phormium 
Colensoi (Cookianum), Astelia montana var., Thelymitra longifolia, Libertia 
ixioides var., Exrocarpus Bidwillii, Nothofagus fusca, N. cliffortioides, Muchlen- 
deckta axillaris, Colobanthus guitensis, Claytonia australasica, Notothlaspi 
australis, Pittosporum divaricatum, Hymenanthera dentata var. alpına, Pimelea 
‚Suteri, Leptospermum scopartum, Anisotome aromatıca, A. flifolia, Griselinia 
littoralis, Dracophyllum rosmarinifolium, Styphelia acerosa, Suttonia divaricata, 
Myosotis Monroi, Veronica buxifolia var., Coprosma Propingua, C. foetidissima, 
C. Cunninghamii (or an undescribed species), Helichrysum bellidioides, Cassinia 
albida var., Olearia virgata var.

A characteristic plant of large stony debris at above ı200 m altitude is 
the summergreen fern, Polystichum! cystostegia.

The mean rainfall of Chatam Island for a period of 24 years (accidentally 
omitted on p. 43) is, according to D. C. Bares, 97 cm. The greatest annual 
rainfall was 123 cm in 1904 and the lowest 62 cm in 1897. re 
24. Page 289. Depleted Central Otago. 
Other indigenous species holding their own on the depleted area of Central 
Ötago are: Poa Lindsayi, Danthonia Buchanani (but cropped closely by sheep 
and rabbits), Urtica aspera (where there are large stones), C/aytonia australa- 
sica (on shady slopes), Oxalis corniculata, Hypericum gramineum and Epilo- 
There is an interesting vernal association of annuals composed mainly of 
introduced species; the following are the principal: Bromus hordeaceus, B. sterilis, 
Hordeum murinum, Festuca myuros, Urtica urens, Cerastium triviale, Myosurus 
arıstatus (indigenous), Ranunculus falcatus, Erophila verna, Erodium Cicutarium, 
Anagallis arvensis, Myosotis arvensis, and M. pygmaea (indigenu).
