It was not observedin the lower forest of the main Ruahine Range, but in the lower forest ofthe Kaimanawa Mountains, on the eastern side, it is present, ascending to3,000 ft. It is recorded from Tongariro National Park by Cockayne, andfrom the higher Waimarino by E. Phillips Turner. On the higher forestof the Ruahine and Kaimanawa Mountains it is certainly replaced by Fagus Aston.—Phanerogamic Flora of Ruahine Mountain-chain. 41 r 30 H«TERviiiJ «)-. -30 ?g / ?.>.*? f if f ,o /, ,2 g ., | OxtfihoT-s trade sTvemm, thus ? „ Colens&s ,, ,, ,, •••«•« L/tJpors Camp* t/ms ? -40 176 42 Transactions. cliffortioides forest, which persists on the Mokai-Patea Eidge up to 4,000 extensive associations of the huge fern Dicksonia lanata recall thoseof Mount Hauhungatahi, both in the open at 2,000 ft., growing like aPteris, as Colenso puts it, and under Fagus forest up to 3,700 ft. Thealmost impenetrable subalpine scrub which occurs on the Tararuas onmany exposed ridges is absent from the Ruahine Range, although theindividual species of the scrub association are usually present, with theremarkable exceptions of Olearia excorticata and 0. lacunosa. The abrupt,transition from forest to tussock meadow or herb-field would seem to beusual where Fagus cliffortioides is the forest, examples being common on thevolcanic plateau.
