BOTANY OF CALOUNDBA. 
REPORT ON EASTER EXCURSION BY G. Iv. 
JACKSON. 
Around Caloundra are areas of fine eucalyptus forest, 
rain forest and tea-tree, boronia and mangrove swamps, 
in addition to a rich beach flora. 
Large areas of eucalyptus forest stretches towards the 
west, a conspicuous feature of these being the enormous 
woolly-butt trees (Eucalyptus saligna). Another common 
tree here is the brush box ( Tristania canferta), which 
overshadow the small but beautiful Persoonia trees, with 
their masses of yellow flowers. The forest oak ( Casuarina 
torulosa ), is thickly scattered over this area, and the tal- 
low wood (Eucalyptus microcorys) is also common. Many 
of the trees bear several varieties of Mistletoe (Lorantkus ) . 
and among the eucalypts are great numbers of grass trees 
(Xanthorrhoea) , which possess a very palatable heart com- 
prised of the base of the younger leaves. 
In the lower portions of this undulating area are 
situated large tea-tree swamps, which contain as well as 
the ordinary Melaleuca leueadendron, some very large 
specimens of the swamp mahogony (Tristania suaveolens ) . 
This last is an extremely hard-wooded tree, and the bark 
was used formerly by the aboriginals for canoe budding. 
In one place the edge of the swamp is dotted with the 
beautiful little purple flower Burmannia , while here and 
there the balloon cotton ( Gomphocarpus fruiticosus ) is 
conspicuous with its large balloon-like seed cases. 
Of rain forest there are two distinct types — the typical 
coastal sand flat scrub such as is found here and there on 
Bribie Island and a much more luxuriant sort found in- 
land about a half mile or so west of Caloundra. In this 
first mentioned the trees are not very large and comprise 
mostly specimens of myrtle or wild cherry (Eugenia ) , 
saffron heart (Halfordm drupifera ) and cypress pine 
(Callitris coliimellaris) . Blueberry ash (Elaeocarmis 
obovatus) is also fairly common, and a wild "rape with its 
small bunches of rather sour fruit is seen everywhere 
draping the trees. The patches of scrub mentioned as 
growing a little way inland are some of them very dense 
and luxuriant, although apparently growin" in almost pnre 
sand. Among the tangle of vegetation lawver cane -nalms 
(Calamus muelleri) seem most prominent, and cabbage 
palms (IAvistona australis) are very common, while pic- 
cabin palms (Archoyito phoenix Cunninghamii) are found
