Warm Subpolar Belt: Bog.
The chief characteristic of the area here considered is the close turf, forming a stiff crust to the soft peaty soil beneath and the sparse occurrence, depauperation or complete absence of the taller species of adjacent formations. A distinct xerophytic habit characterises all the dominant species, undoubtedly due to the fact that during the summer most of them dry up at intervals and perhaps also to their continual exposure to drying winds.
The dominant constituents of the association are usually some of the following: Schoenus pauciflorus, Carpha alpina, Oreobolus pectinatus, Gaymardia ciliata, Astelia linearis. Generally common are Caltha novae-zealandiae, Plantago Brownii, P. uniflora (especially on the brinks of tarns), Isolepis aucklandicus, Juncus antarcticus, Drosera stenopetala, Forstera Bidwillii, Caladenia bifolia, Coprosma repens, and in several localities Abrotanella pusilla. Stunted forms of Ranunculus geraniifolius (particularly the variety with much dissected leaves), Celmisia spectabilis, C. hieracifolia oblonga, and Senecio lagopus are also commonly present.
