tonia divarıcata is dominant and to this especially is the extreme density due. 
The scrub varies from ı— 2 m in height, according to exposure; its surface is uneven. 
Dracophyllum scrub is the common scrub-association of Campbell Island. 
The members are: — Dracophyllum subantarcticum (dominant); D. Zongifolium, 
D. scoparium (rare), Suttonia divaricata, Coprosma parviflora, C. ciliata, C. 
 cuneata together with Blechnum capense and Polystichum Velun when suf- 
ficiently open. Seen from a distance, the association presents an even surface 
and recalls Leptospermum heath of the main islands of New Zealand. The 
relative proportion of Dracophyllum or divaricating-shrubs varies in different 
localities and situations, so that either growth-form may dominate and, in the 
‚latter case, the association, according to LAING (1909 :488) might be called 
Coprosma betab Dracophylium scrub is equally as dense as the allied asso- 
ciation of the Lord Auckland’s from which it differs only in the greater abun- 
dance of the Dracophyllum form, in the absence of Metrosideros, Cassinia 
and Coprosma foetidissima and in the presence of the two.species of Draco- 
phyllum. Antipodes Island scrub occurs in the sheltered gullies, descending 
in long dark lines down the hillsides. It consists of Coprosma ciliata and C. 
cuneata and attains a en of about 1.5 m. Eralır Polystichum vestitum 
is an associated species. 
3. Moor. = 
“Moor”, as here used, includes the various *meadow” and “bog” associ- 
tions of my previous writings, (1904 and,ı909). It occurs throughout the 
 Subantarctic province and embraces two distinct types of association, viz. — 
tussock-moor and herb-moor. 
Tussock-moor. 
 Tussock-moor consists of 3 distinct associations defined by the presence 
of Poa foliosa, P. litorosa or Danthonia antarctica as the dominant Kr 
Poa foliosa moor occurs on the Snares and Aucklands and probably, to 
some extent, on the Campbell’s and Antipodes’). The association stands out 
 conspicuously through its bright-green colour. The tussocks are about 5soem 
high and 55 cm in diam.; they grow closely and the broad leaves droop some- 
what. On the Snares, Stilbocarpa robusta is a companion-plant, either a 
or in broad patches, its darker-green, great orbicular leaves contrasting with 
the paler grass. Asplenium obtusatum and Blechnum durum occur sparingly: u 
On Lord Auckland’s Islands, apart from a frequent belt of varying breadth 
near the shore, where Carer trifida is a member, Poa foliosa moor. exists 
merely as kinall pure patches in n Poa litorosa association. 
Poa litorosa moor is common on the Snares, Campbells, Aue and
