(forma), Drapetes Dieffenbachii, and Anisotome aromatica. Euphrasia zelandica, Forstera tenella, and Oreomyrrhis andicola also occur, but not so abundantly. This formation is found on all the tops from Mount Sinclair to Castle Rock, but for some reason does not occur on French Peak (2,600 ft.) to Saddle Mount (2,700 ft.). It reappears on Mount Bossu (2,500 ft.) and the neighbouring Carew's Peak (2,600 ft.), and traces of it reappear on Brasenose (2,500 ft.) behind Akaroa Township. Other species of the subalpine pasture are Danthonia Raoulii var. rigida, Aciphylla Colensoi, Raoulia glabra, and R. subsericea. Dantltonia Cunninghamii and Gunnera monoica are also sometimes to be found. This little subalpine florula is, of course, as much isolated as if it stood on an island off the coast, and it is somewhat difficult to account for its presence here. Either it has been brought by birds or winds, or else it is a remnant of a vegetation that in glacial times reached to the sea-coast and extended widely over the country. We have not the data at present to solve the problem, and it can only be considered in connection with the general geological evidence and with the distribution of alpine species throughout New Zealand. It is, of course, to be expected that in this latitude windswept mountain-tops should carry some subalpine species above 2,500 ft. Such species are found near Dimedin as low as 1,500 ft., and in Stewart Island at sea-level. In some cases, however (e.g., View Hill, French Peak), the forests were able to maintain themselves on hilltops up to 2,500 ft. This may be due to edaphic conditions, for these peaks are perhaps less rocky than those which are bare.
