T. Krex.—On the Botany of Islands in the Hauraki Gulf. 447 
derris phylicifolia is, perhaps, the most abundant; Dracophyllum squar- 
rosum, Leucopogon fasciculatum, L. frazert, Cyathodes acerosa, Gaultheria 
antipoda, Coriaria ruscifolia, etc., are common. The more frequent grasses 
and herbaceous plants are Sporobolus elongatus, Agrostis emula, A. quadriseta, 
Triticum multiflorum, Poa anceps, Dichelachne crinita, Microlena stipoides. 
Glyceria stricta was collected in a single locality on the coast. Geranium 
molle, G. microphyllum, G. dissectum, Oxalis corniculata, Pelargonium clandes- 
tinum, Acena sanguisorbe, Halorayis alata, H. diffusa, Epilobium pubens, F. 
junceum, E. rotundifolium, E. nummularifolium, — brachiatus, Gna- 
phalium collinum, G. luteo-album, G. involucratum, Wahl yia gracilis, etc., 
ete. In most places Cladium sinclairii, C. gunnii, Schenus tendo, S. tenax, 
etc., with a few orchids, of which the most frequent were Microtis porrifolia, 
Thelymitra longifolia, and Orthoceras solandri. Phormium tenax, with several 
species of Juncus, Carex, Gahnia and other sedges, occurred in marshy 
places, especially on the borders of forests, but, as a rule, paludal plants 
were poorly represented. | 
Arborescent ferns are represented by Cyathea medullaris, C. dealbata, 
Dicksonia squarrosa, and very rarely by Hemitelia smithii; none of the rarer 
kinds were observed. The ferns and allied plants generally were remark- 
ably few in number; besides the tree ferns, the most striking are Lomaria 
Jraseri, and Lygodium articulatum. 
I have already mentioned the general resemblanee between the chief 
physical features of the Kawau and Waiheke. Although the total number 
of ferns on the latter island is greatly below that of the Kawau, the resem- 
blance between the Phenogamic portion of the flora” of both is remarkably 
close. I can only enumerate three plants as occurring on Waiheke, which 
are not also found on Kawau: they are Hymenanthera tasmanica, Pimelea 
arenaria, and Melicytus micranthus; the first and second of these are 
extremely rare, the third occurs in several localities, and in all probability 
is to be found on Kawau, although not observed either by Mr. Buchanan or 
myself, 
The kauri and tooth-leaved beech, both of which are rare on Kawau, 
occur or rather have occurred on Waiheke in considerable quantity. 
Coprosma arborea is also more plentiful on the latter island than the former, 
and the same remark applies to Metrosideros robusta, of which only a single 
specimen is known in Kawau. The large tea-tree, although plentiful on 
that island, never occurred in such great abundance as on Waiheke. On 
the other hand, one of the most characteristic plants of the Kawau flora, 
* Of course excluding numerous species, such as e Jilicaule, Juncus nove- 
zealandie, Uncinia rubra, Eryngium vesiculosum, etc., etc., erroneously recorded as 
indigenous wau. See Trans. N.Z. Inst., IX., pp. 625-527,
