banks of rivers or creeks, rapid in growth, and like the preceding 
attaining a height of 100 feet or more, but differing from it in grow— 
ing almost exclusively near water. 
5. H. radiata, a variety of H. amygdalina (F. v. M.,) called ‘River 
White Gum.” This is a tree of moderate size, found only on the 
banks of rivers or creeks, having the bark depending in long strips 
from the upper branches, and the leaves frequently opposite. The 
wood is soft. . amygdalina is the ‘*‘ Messmate” of the Southern 
Ranges and attains gigantic proportions, but H.7adzata seldom rises 
above forty or fifty feet, and flowers even in a shrubby state. 
6. H. Gunnit, “the Swamp Gum Tree” of some districts which 
does not attain the large size in N.S. Wales as in Victoria, and 
prefers in the former colony the sides of moist ranges where it 
flourishes at a considerable elevation above the sea. It is a species, 
which being common to Tasmania and the Southern districts of 
N.S. Wales, seems to require similar conditions to those of E. 
globulus for its perfect development. ° 
7. E. polyanthema, the “ Poplar Leaved Box” or ‘“ Lignumvite,” 
the latter name being derived from the hardness of its wood. 
Though described as growing on dry ridges and hills, and rising 
exceptionally 250 feet, it is found in N.S. Wales on creeks or moist 
flats, and is comparatively a small tree and of slow growth. 
8. E. rostrata, or “ River Gum,” the most widely distributed 
Eucalypt in Australia. Baron Mueller regards this species as the 
most important of the whole genus, not merely on account of its 
therapeutic and economic properties, but because it is exceedingly 
rapid of growth and admirably adapted for “ grounds with stagnant 
humidity.” It is remarkable that H. rostrata does not occur on 
the eastern side of the Dividing Range in N.S. Wales. 
I have brought these Eucalypts under the notice of cultivators, 
as the species appear well calculated for the purpose of counteracting 
the baneful influences of malaria, and of flourishing under conditions 
similar to those of H. Globulus ; whilst as some of them occur at 
different elevations and in various geologic formations, they may 
supply the place of that species in regions where experience shows 
is is unsuited for the climate or soil. Of all the species in N.S. 
Wales, none are so likely to succeed in moist or depressed localities 
as those indicated, and it would be for the public benefit if the 
Government were to try the experiment of planting them for forest 
purposes. H, Globulus has acquired a world-wide reputation and 
deservedly so, but the properties .of other species remain to be 
developed, and to afford to medicine and the arts a means of 
ameliorating the ills of humanity. Baron F’. yon Mueller has treated 
nobly of the genus Eucalyptus, in his splendid work Hucalypto- 
graphia, and whilst I would bear testimony to the accuracy of that 
eminent botanist in his descriptions of species (so far as known to
