Towai.--_Fagus fusca._ This is the largest and by far the most attractive tree growing in the vicinity of the high mountains of this portion of the island. It is somewhat stunted around Tongariro, but attains to colossal size on the western slopes of Mount Ruapehu. Tumigi.--_Leucopogon fasciculatus_ is a shrub having small, thick leaves, with white underneath. It is very plentiful at Tongariro. Tutu.--_Coriaria mystifolia_ is common in mountains and dry places. Waewaekohu.--_Gleichenia dicarpa_ is a widely distributed mountain plant. The _Gnaphalium bellidioides_ is a mountain plant met with in both islands. This plant was the last sign of vegetable life on Tongariro, where it grew up to an altitude of 6000 feet. I also found it growing on Ruapehu, with the _Ligusticum aromaticum_, at an altitude of 7000 feet, where both these plants likewise formed the last sign of vegetation. It is worthy of remark that the natives could give no names for these latter species. GRASSES. Kakaho.--_Arundo Australis._ A tall grass or reed, very common around Lake Taupo.
