scrub is constituted of Casuarina distj/la, Banhsia onarrfinata^ 

 Hakea Jlexilis, Melaleuca gihhosa, M. uncinata, JEucahiptus 

 capitellata, E. gracilis, E. cosmophylla, E. incrassata, JCantlio- 

 rrhoea quadrangulata, Acacia armata. The constituents of the 

 more heathy portions are Leptospermum scoparium, AdenatJws, 

 spp., Ohoretriim glomeratum, Prostanthera, spp., Dodoncea Baueri, 

 Bertya rotundiiolia^ GalycotTirix, Eremophila Broivnii, LJiotzlcya 

 glaberrima, Styphelias, PetropJiila multisecta, Ixodia achilleoides , 

 Hakea rugosa^ H. rostrata, Logania ovata, Spyi'idiums, Boronia 

 filifolia ; the larger shrubs infested with Cassytha melantha, 

 and the smaller with C. puhescens and C. glabella. Whilst the 

 chief herbaceous plants are Lepidosperma Jlliforme, Lobelia 

 microsperma, Thysanotus dicJiotomus, Candollea graminifolia, 

 Schoenus Tepperi, Goodenia geniculata, Trachymene heterophylla, 

 Xantlwsia dissecta, Loudonia Behrii. The interspersed clay- 

 flats are chiefly occupied by Lepidosperma viscidum, Juncus pal- 

 lidus and Clwrisandra enodis, margined with thickets of Calli- 

 stonon coccineus and Melaleuca gibbosa. In a few instances 

 trees of either Eucalyptus corynocalyx, E. rostratus, E. leu- 

 coxylon, or E. cosmophylla form an open forest, beneath which 

 the herbage is more varied. Where the soil is saline, Melaleuca 

 pustulata forms a dense woodland growth, though of low 

 stature. 



2. The Sylvan Vegetation is confined to the borders of the 

 watercourses, and the chief forest tree is Eucalyptus coryno- 

 calyx, with which is associated not infrequently E. leucoxylon, 

 and occasionally E. rostrata and E. viminalis. The banks of 

 the streams are quite concealed by an impenetrable growth of 

 Acacia retinodes, Leptospermum lanigerum and L. myrsinoides. 

 In the shade of these jungle-like growths luxuriate many 

 species of herbaceous plants, whilst the forest-glades are rich 

 in many shrubby plants, which do not occur on the scrub-lands. 

 Such are Grevillea parvijlora, Pomaderris racemosa, Bursaria 

 spinosa, Acacia rupicola, A. verticillata, Exocarpos cupressiformis . 

 Here the grass-trees attain unusual stature, the trunk reaching 

 to a maximum height of fourteen feet, and the spike to sixteen 

 feet; and in association with loftier plants they lose the weird- 

 like appearance, which they present on the open lands, and 

 impart quite a tropical aspect to the floral scenery. 



3. The Savanna Vegetation. — On the north coast of Dudley 

 Peninsula the hill-slopes are more or less grassed, and have 

 scattered over them groups of Gasuarina quadrivalvis. The 

 same appearance is seen at Kingscote. In both areas the meta- 

 morphic rocks are almost denuded of soil. But on the north 

 slope of the Freestone Range, as about Emu Creek, a fine 

 park-like country occurs, dotted here and there with clumps 

 of Eucalyptus cneorifolia, the habit and foliage of which have
