the fairly broad band of rich rain forest on its lower 
flats, but it possesses the same Eucalyptus (Blue Gum 
Bloodwood) formation on its upper flats. The vegetation 
indicates that these larger streams in the southern part 
of the coastal portion have influenced the soil adjacent to 
them. 
The third class of Streamside Associations is con- 
nected with the largest creeks of the coastal portion, 
namely Plane Creek and Carmila Creek. In both these in- 
stances the extensive flats bordering the streams and their 
main tributaries are cultivated. The flats adjoining Plane 
Creek appear to have been cultivated for some time, and 
the clearing of the vegetation has gone so far as to leave 
insufficient primeval forest to base observations upon. In 
the previous paragraph the existence of lower and upper 
flats adjacent to the main stream of Carmila Creek is 
mentioned and their types of vegetation outlined. In this 
instance vestiges of the original vegetation which remain 
are sufficient for observation. The rain forest on the 
lower flat is the heaviest and most luxuriant of the whole 
area reported on, in spite of the fact that the rainfall is 
47 inches, which is a fairly low figure for rain forest of 
a luxuriant type. Possibly part of the moisture require- 
ments of the rain forest is supplied from the stream by 
gravitation and capillarity. The principal trees in the rain 
forest of the lower Carmila flats are: Milky Pine (AU 
stonia scholaris ), numerous large trees; Cluster Pig 
( Ficus glomerata) ; Quandong ( Elaeocarpm grandis) ; 
Bangalow Palm. ( Archontophoenix Cimninghamii) ; 
Native Nutmeg (Mvristica insipida) : Pisonia Brunoniana; 
Mackay Cedar (Albizzia Toona) ; Terminalia sp .; Axe- 
handle Wood ( Pseud ornorus Brunoniana ) , Aphananthe 
philippincnsis , Brown Kurraj ong ( C ommersonia echin - 
ata) , Musk Wood ( Marlea vitiensis ), Bmistoa sapindi - 
formis. In places there are a few very large Tea Trees 
(. Melaleuca Leueadendron var. mimosoides) overhanging 
the stream. 
The Blue Gum and Bloodwood formation of the upper 
flats of Carmila Creek border on Tea Tree country. The 
upper flats are cultivated but are not so productive as 
the lower ones. In the upper reaches of Carmila Creek 
and its tributaries the extent of the rain forest of the 
lower flat is very restricted.

In this section the vegetation of the ranges and foot- 
hills will be discussed. The ranges consist principally of
