The _flora_ of Tongariro and the surrounding region partakes of an alpine character, and is both varied and beautiful. Indeed, not only are many of the mountains forming the group clothed with a dense and attractive vegetation, but where the forests spread down to the plains, the trees and shrubs are often so disposed by Nature as to form perfect gardens, which appear to have been artificially planted. During the exploration of both Tongariro and Ruapehu, I had an opportunity of examining the varied growth of trees, shrubs, and plants; and although I was unable, under the circumstances, to make a very extensive botanical collection, I secured some of the choicest specimens of mountain plants, and afterwards obtained their native names from the Maoris. Houhou.--_Panax Colensoi_ is an abundant plant in hilly districts. Huripo.--A tall shrub, common around Tongariro, and remarkable for its foetid smell. Manao.--_Pittosporum fasciculatum_ is found in both islands. Monao.--_Cyathodes acerosa_ is plentiful throughout the whole country. Papauma.--_Griselima littoralis_ is a plentiful tree, especially in the high interior districts. Patotara.--_Leucopogon Colensoi_ is a common mountain plant found in both islands. Peki Peki.--_Clemisia spectabilis_ is an alpine plant, abundant on the open mountains of the South Island, but is seldom found in the north. Purea.--_Cassinia fluvida_ is a plentiful mountain plant on both islands. Rimu.--_Dacrydium laxifolium_ is abundant on the high mountains. It is the smallest known pine in the world. Taubinu.--_Olearia nummularifolia_ is plentiful on the mountains of the South Island, but is found less frequently in the north. Toatoa.--_Phylloctadus Alpinus_ is a sub-alpine tree, frequently met with in both islands.
