D. The Herb-Field.

True herb-field is developed to only a small extent at Mount Peel, although on the southern faces of the subalpine belt there is much Celmisia Lyallii fell-field which approximates to, and in favourable places—sheltered, gentle, rather shaded slopes—merges into the herbfield now described. Celmisia Lyallii is in general dominant, and is always of physiognomic importance. The following fell-field plants are abundant: Lycopodium fastigiatum, Poa Colensoi, Carex Wakatipu, Luzula campestris vars., Anisotome aromatica vars., Gentiana corymbifera, Celmisia Haastii, C. viscosa. Common are Danthonia flavescens, Viola Cunninghamii, Drapetes Dieffenbachiii, Epilobium tasmanicum, Celmisia discolor. The other members of the fell-field are infrequent or absent.

In addition to the fell-field plants we find Lycopodium Selago, Poa Kirkii, Schoenus pauciflorus, Uncinia compacta, Oreobolus pectinatus,

Ranunculus Enysii, R. gracilipes, R. Monroi forma dentatus, Gentiana bellidifolia, Geum parviflorum, G. leiospermum, Hydrocotyle novae-zelandiae var. montana, Gaultheria depressa, Myosotis pygmaea, Ourisia caespitosa, ‘Euphrasia Monroi, E. Laingii, Plantago Brownii, Coprosma repens, Lobelia linnaeoides, Nertera depressa, Forstera Bidwillii, F. tenella, Senecio bellidioides, Celmisia sessiliflora. The association is thus characterized by its closed nature, the variety and individual abundance of its herbs, and the infrequence of woody plants. On its lower margins it usually merges into a Hebe shrubland. Beyond a rare example of *Rumex Acetosella and *Hypochaeris radicata in barish patches caused by small slips, exotic plants are absent.

In the flushed ground above stream sources Celmisia Haastii assumes a local dominance, giving a greyish green tint to the whole slope. Streamsides are much richer in plants than those of the fell-field. Here to be found are Schoenus pauciflorus in quantity, Scirpus aucklandicus, Carex Raoulii, Poa imbecilla, Cardamine heterophylla var., Oxalis lactea, Ranunculus Monroi, Schizeleima hydrocotyloides, Senecio Lyallii vars., and in the water abundance of Epilobium macropus and Montia fontana. On gravelly margins are Claytonia australasica, Raoulia tenuicaulis, Epilobium pedunculare var.,.Ourisia caespitosa.
