the Days Bay pavilion. The altitude is about 1,000 ft. The forest is the original southern-beech association of these hills, and is composed of the following trees:— Forest-trees: Nothofagus Solanderi, N. fusca (both very plentiful), Weinmannia racemosa (very common), Metrosideros robusta, M. florida (liane), Elaeocarpus dentatus, Podocarpus ferrugineus, Griselinia littoralis (small tree), Suttonia salicina (small tree), S. Urvillei, Coprosma grandifolia (small tree), Knightia excelsa, Drimys axillaris (small tree). Undershrubs: Coprosma foetidissima, C. Colensoi, C. lucida, C. rhamnoides, Cyathodes acerosa, Leucopogon fasciculaius, Dracophyllum Urvillianum var. filifolium, Nothopanax Colensoi, Cyathea dealbata. Floor: Polypodium grammitidis, Cyclophorus serpens, P. Billardieri, Hymenophyllum demissum (with several other species, very common), Trichomanes reniforme (common in patches), Blechnum capense, Lindsaya viridis, Asplenium flaccidum, Dianella intermedia, Astelia nervosa, Pterostylis Banksii, Gahnia spp., Uncinia filiformis and other species. The forest-floor is covered in many places by a dense growth of filmy fern (Hymenophyllum spp.) and kidney-fern (Trichomanes reniforme), while mosses, liverworts, and fungi are present in patches. Undershrubs are present but are not closely spaced. Above the ground-level is in most cases 1 in. to 3 in. of decayed vegetable matter, held together with a network of fine roots, while above this is a fine layer of loose debris (leaves, twigs, &c.). The subsoil, which comes close to the surface, is mostly a greywacke rock. The situation is on a fairly steep slope, and the dense foliage of the beeches combined with the southerly aspect renders it somewhat darker at the ground-level than is the case in the second locality. Owing to the above factors and its altitude (1,000 ft.) it is also considerably colder. The exact conditions are given in connection with each sample taken. Tawa Forest. The second locality is a similarly-sized portion of forest in the middle of the remnant of a formerly more extensive rain forest to the south-west of Wadestown, known as Chapman's Bush, now a portion of the Wellington Corporation reserve. This is largely a tawa forest. A list of the plants occurring in this limited area as given by Mr. B. C. Aston is as follows:— Forest: Beilschmiedia tawa, Elaeocarpus dentatus (hinau), Olea montana, Metrosideros robusta (rata), Knightia excelsa (rewarewa). Small trees and shrubs: Pennantia corymbosa (kaikomaka), Metrosideros florida (liane), M. scandens, Griselinia lucida (epiphyte), Rhipogonum scandens (liane), Parsonsia heterophylla (liane), Astelia Solandri (epiphyte), Suttonia australis, Coprosma grandifolia, C. robusta, C. crassifolia, C. areolata, C. rhamnoides, Macropiper excelsum, Geniostoma ligustrifolium, Brachyglottis repanda, Cyathea dealbata, Myrtus bullata. Floor: Dryopteris velutina, Blechnum filiforme (epiphyte), Asplenium lucidum, A. flaccidum (epiphyte), A. adiantoides (epiphyte), Polypodium Billardieri. The material of the forest-floor covering is generally much looser, less decayed, and less matted by roots than is the case in the first one. The altitude is only about 100 ft. above sea-level. Owing to less density in the
