area. It is most frequent on dry, highly siliceous ridges. 
Forest Oak ( Casuarina suberosa) is not 'widely dis- 
tributed. Patches of it occur in the grass tree country 
south of Mt. Christian, and an occasional tree is seen on 
dry ridges near the Mt. Funnel Range. 
Honeysuckle ( Banksia integrifolia) is rare in the 
portion, and occurs on dry hillsides. 
Acacia flavescens is only found on the highly siliceous 
soils, and is often accompanied by Grass Tree and Scrub 
Box. 
( b ) Streamside Forests 
The Streamside Associations comprise the vegetation 
of creek banks and their adjoining flats. Greek banks and 
flats, although they represent a very small proportion of 
the total area of the coastal portion, are very important 
from a qualitative standpoint. Undoubtedly this class of 
land has exercised a very great influence in the settle- 
ment of the area. These associations are divisible into three 
classes according to the extent to which rain forest and 
rich Eucalypt forest have been developed. The smaller 
streams support only a very narrow fringe of vegetation 
differentiated from the surrounding country. The domin- 
ant species found on the banks of the numerous small 
streams throughout the coastal portion are: River Oak 
( Casuarina Cunningliamiana) , Creek Tea Tree ( Melaleuca 
Leucadendron var. mimosoides ), Red Bottle Brush (Cal- 
Listcmon viminalis ), Fandanus sp. In addition to these, 
often a few Bangalow Palms (Archonto phoenix Cunning- 
hamii) , Milky Pines ( Alstonia scliolaris ), a Native Fig 
Tree ( Ficus Cunningliainii) and Bill ipillies (E ugenia 
australis) are found. 
The second class of Streamside Associations consists 
of a narrow fringe of rain forest on the banks of the 
stream and beyond this fringe a flat of varying extent 
maintaining a good class of Eucalyptus forest in which 
large Blue Gums and Bloodw'oods predominate. These 
Eucalypt flats are often cultivated. The following creeks 
are characterised by this type of vegetation : Marion 
Creek, West Hill Creek and Flaggy Rock Creek. This 
type of creek vegetation is developed chiefly in the south- 
ern part of the coastal portion from Mt. Funnel Range 
southwards. All the larger streams in this southern part 
are of this class, and the present cultivated areas are al- 
most confined to the flats adjoining these streams and 
their tributaries. Carmila Creek is the only exception to 
this generalisation. It differs from the other streams in
