none of tlie sombreness and quaiutness, wMcTi cliaracterise 

 many of its congeners ; intermingled are JE. incrassata and 

 JE. santalifolia. This kind of vegetation merges on tlie one 

 tand into that of the heathy ground at lower elevations, and 

 into that of the sugar-gum tree, forests of which crown the crest 

 of the range and occupy its ravines. 



4. The Yegetation of the Littoral Tracts. — The mud flats 

 around the shores of ISTepean Bay, Bay of Shoals and Pelican 

 Lagoon have the customary assemblage of plants affecting 

 such situations — Lepigonum marinum, Salicornias, Siiceda, Mesem- 

 hrianthemum aiostrale, Atriplex paludosum, Polycnemon, Samolus, 

 Melaleuca pustulata. Passing into the subsaline plains 

 coterminous with these, we meet with an herbage of Sporobolus 

 virginicus, amongst which the above-mentioned plants also 

 grow; and in addition may be noted Agrostis Solandj'i, 

 Poa ccBspitosa, Juncus pallidus, Centipeda Cimninghami^ Bulhine 

 semiharhata, Myoporum insulare, JRhagodia crassifolia and 

 Sisyrnichium. The banks of shell sand and blown sand yield a 

 number of the species of the scrub- lands ; but as almost con- 

 fined to these situations may be mentioned Oallitris verrucosa, 

 Itodoncea viscosa, Myoporum viscosmn, Mesemhriantheinum cequi- 

 laterale, Clematis microphylla, Scirpus nodosns, 8pinifex hirsutus, 

 Atriplex cinereum. On the rocky shores and adjacent slopes 

 there occur JRhagodia crassifolia., Nitraria Schoeheri, Geijera 

 parvifolia, Alyxia huxifolia, Pittosporum phillyrceoides, Enchy- 

 Icena to7nentosa, Muehlenheckia adpressa. The hills of blown 

 sand and calciferous sandstone, which dominate the whole of 

 the coastline on the south side of the island, yield a variety of 

 plants. On the inner slopes of the sand dunes are dense 

 thickets composed of Eucalyptus incrassata, E. santalifolia, 

 Melaleuca parvifolia, Acacia retinodes and A. armata ; here 

 occur Veronica distans, Selichrysum leucopsiditnn, Ixolcena supina, 

 Mesemhrianthemum cequilaterale, Lotus australis, DodoncBa 

 Jiumilis, Kunzea pomifera, Lepidosperma gladiatum, Goodenia 

 varia, SccBvola crassifolia, Styphelia Bichei, S. ovalifolia, Scirpus 

 nodosus. 



The Vegetation of Dudley Peninsula is largely of the sylvan 

 and savanna types ; over the area occupied by mica-slate, are 

 natural pasture-lands interspersed with she-osik, Melaleuca parvi- 

 flora and the narrow-leaf mallee, merging into mallee scrub, 

 chiefly constituted of Eucalyptus cneorifolia and E. incrassata, 

 but not dense enough to obstruct the passage of man or horse. 

 On the northern water-shed, the slopes are seamed with short 

 and steep gullies ; but on the opposite side, the stream courses 

 are long and bordered by wide flats of drift deposits. The flats 

 are covered with natural grasses, chiefly Stipa aristiglumis, Poa 

 ccBspitosa^ Festuca hromoides, Danthonia penicillata and Agrostis
