dilatatum entirely replaces the Digitaria and is then 
usually associated with Pennisetum alopecuroideum and 
Sporobolus capensis. In distinctly swampy places Pas- 
palum distichum is the dominant species. 
The pastures have suffered considerably from over- 
grazing.

(Flaggy Rock is situated on the main North Coast 
Railway Line, 136 miles north of Rockhampton. Sarin a 
is on the same line, 43 miles north of Flaggy Rock. Some 
years ago the author had the opportunity of observing the 
forests of this area in some detail. — Editor.) 
(a) TREES OF THE FLATS AND HILLS. 
Eucalypts and Tea Trees are the dominant species 
throughout. Therefore the whole section can be conveni- 
ently embraced by the term E ucalyptus-Melal euca asso- 
ciation. Another genus of trees, Tristania , which includes 
the Swamp Mahogany, is also frequently represented. The 
Eucalypts, Tea Trees and Swamp Mahogany occur in pure 
or mixed stands. There are many thousands of acres of 
flats and gradual slopes covered with Tea Trees unmixed 
with other forest species. Three varieties of Tea Trees are 
represented in the coastal portion. Melaleuca Leucaden - 
dron var. Cunning luirnii is the very common one. The 
White Tea Tree, Melaleuca Leucadendron var. minor is 
only seen in the southernmost part from Carmila south- 
wards, It is sparsely scattered throughout the more abund- 
ant Cunninghamii. The Drooping Tea Tree, Melaleuca 
Leucadendron var. mimosoides is a larger variety than the 
other two. It has pendent branchlets and foliage and is 
confined to the banks of watercourses and water holes. The 
very common variety Cunninghamii is a small tree and in 
this area varies in height from about 20 — 40 feet. 
There are a number of Eucalypts in the coastal por- 
tion: Poplar Gum ( Eucalyptus alba), Blooclwood (E. 
corymbosa), Blue Gum (E. tereticornis), Ironbark (E. 
drepanophylla) , Narrow-leaved Ironbark (E. crebra ) , 
Silver-leaved Ironbark (E. melanopMoia) , Moreton Bay 
Ash (E. tessellaris), Cabbage Gum (E. pap u ana) and 
Stringybark (7?. acmenioidcs) . Other large forest trees in
