more soil accumulates, or where the cliff is less steep, by a shrub-association

Rocks rising out of subalpine herb-field, standing on old moraine or form- 
ing steep buttresses, eär early on more or less covered with peat and bear 
a vegetation of many of the species from the adjacent herb-community anda 
few that are more truly rock-plants. These latter include Aymenophyllum mul- 
zifidum (epharmonic form with curled leaf-segments), the grass Microlaena 
Colensoi, the prostrate shrubby Dracophyllum Kirkii (Western district), Ani- | 
sotome pilifera, Aciphylla Monroi, Celmisia Walkeri (Plate XLVI, Fig. 69) and.
