Art. V.—Notes on the Botany of Routeburn Valley and Lake Harris Saddle. By D. L. Poppelwell. [Read before the Otago Institute, 7th October, 1913.] During the Christmas holidays of 1912 Mrs. Poppelwéll and myself spent the period from the 27th December, 1912, to the 1st January, 1913, at Routeburn Hut, during which time we twice visited Lake Harris Saddle, and took notes of the botany of the valley generally. Although, this locality has frequently been visited by botanists, I can find no published description or list of its plants. I propose, therefore, without dealing exhaustively with the various plant associations, to describe some striking characteristics of the plant covering, and to give a list of the plants noted by me. There are also some peculiarities regarding the distribution of the plants in the locality which are interesting as much on account of what is missing from the associations as on account of what is present. Lower Routeburn Valley. The forest in this valley is almost entirely a beech one, and, as is usual, there is not much undergrowth. Here and there, however, along the damp gullies there are found such species as Carpodetus serratus, Gaya Lyallii, Coprosma lucida, Olearia nitida, Nothopanax simplex, N. Edgerleyi, N. Colensoi, Griselinia littoralis, Senecio elaeagnifolius, Muehlenbeckia complexa, Phyllocladus alpinus, Podocarpus Hallii, and a few others. The principal ferns are Hymenophyllum demissum, Histiopteris incisa, Blechnum penna marina, Polypodium australe, Polystichum vestitum, Asplenium flaccidum, A. Richardi (?), and Blechnum fluviatile (rare). Of the smaller plants in the lower open valley glades and forest the principal consisted of Acaena Sanguisorbae, A. microphylla, Muehlenbeckia axillaris, Wahlenbergia saxicola, Veronica Lyallii, Lagenophora petiolata, Luzuriaga marginata (rare), Coriaria angustissima, Ranunculus lappaceus, Helichrysum bellidioides, Hydrocotyle novae-zealandiae, Claytonia australasica, Viola Cunninghamii, Ranunculus hirtus, Angelica Gingidium, Anisotome brevistyle, Gastrodia Cunninghamii, Urtica incisa, Geum parviflorum, and Craspedia uniflora. On the Routeburn Flat I noted Poa Colensoi, Agropyron scabrum, Celmisia longifolia, Viola Cunninghamii, Cotula dioica, C. squalida, Cardamine heterophylla, Craspedia uniflora, Microseris Forsteri, Senecio Lyallii, and Mysotis macrantha, the two latter on the creekbanks, with several species of Epilobium—i.e., E. pubens, E. pycnostachyum, E. linnaeoides, E. rotundifolium, and E. melanocaulon. The Upper Routeburn Valley. Just where the track emerges from the forest, at a height of about 3,300 ft., a magnificent view of the alpine scrub is obtainable, and as its association differs from, most others in this locality it is worth describing. It is exceedingly dense and externally is rounded and smooth, but of various colours. The prevailing colours are green, brown, and white. Perhaps the brown is the most marked. This is brought about by the abundance of Podocarpus nivalis, which is very plentiful, especially in the lower part of the scrub. Higher up a greenish-brown tinge is given by Dracophyllum
