fall or soil, or with both of these conditions. The rainfall 
at Koumala is 54 inches, and at Sarina 68 inches per year, 
while that of the Eungella Range is 65 inches per annum. 
It is, therefore, assumed that the limiting factor in the 
growth of these rain forests is connected with the soil. 
The principal large trees in the rain forests are: 
Mackay Cedar ( AlHzzia Toona ), Milky Pine ( Alstonia 
soholaris ), a native Pig ( Ficus C unninghamii) , Booyong 
( Torrietia Argyrodendron) , Black Jack (Tarrietia actm- 
ophylla ■), Coondoo ( Sideroxylon Richard, ii) , Ribbon 
Wood (Euroschinus falcatus ), Cordia aspera , and Cud- 
geree ( Flindersia Schottiana). Among the smaller trees 
the following may be mentioned : Hauer ( Dissiliaria bale- 
ghioides ), Native Nutmeg (Mynstica insipida ), Ochrosia 
Kilneri, Cryptocarya triplinervis, Linociera ramiflora, 
Muskwood (Marlea vitiensis var. foment osa) Sideroxylon 
argent e urn , Phaleria Neumanni , Eandia Fitzalanii, Ard- 
ma pseudojambosa , Glossy-leaved Stinging Tree ( Laportea 
photiniphylla) , Broad-leaved Stinging Shrub (Laportea 
m, oroides), Macaranga Tanarius, Kamala (Mallotus philip - 
pinensis) , Axe-handle Wood (Pseudomorns Brunoniana ) , 
Aphananthe philippinensis , Trema orientalis, Gloehidion 
Ferdinandi. 
The common vines of the rain forest are wild grape 
vines (TiMs ») and Flagellar ia indica. 
Mackay Cedar and Milky Pine are the commonest of 
the large trees in the rain forest. The Mackay Cedar is a 
tall-stemmed typical rain forest tree in this environment, 
and its habit here is strongly contrasted with the one it 
assumes in tlie Eucalyptus-Mclaleiica Association of the 
coastal portion. The species yields a good cabinet wood. 
The Stinging Tree (Laportea photiniphylla) is an exceed- 
ingly common tree of the rain forests. 
On parts of the mountains there are groves of Bunga- 
low Palms (Archonto phoenix C unninghamii) . These 
groves are parts of rain forest areas and contain rain- 
forest undergrowth.

(N.S.W). on the 9th January of this year, we lost one of 
the keenest students of the botany of the interior of New 
South Wales, and adjacent states in this country. Morris
