brick wall, and then developing enormously after the water is

E. globulus is the species referred to by European and American 
writers, as being the best-known and most highly-appreciated of the 
genus ; but as that species, though suitable for some climates and 
surpassing many species in the rapidity of its growth, does not 
extend beyond the south part of New South Wales, nor when 
planted in the neighbourhood of Sydney does it appear to flourish 
and attain longevity, it is well to bearin mind that besides LE. 
Globulus there are other Eucalypts, which occur naturally in a more 
northerly latitude and under different climatic and geologic circum- 
stances, and that these species, while possessing properties very 
similar to those of E. Globulus, may thrive where that species does 
not. The species to which I would refer, as calculated to promote 
in a greater or less degree the advantages resulting from the planting 
of Eucalyptus-forests in marshy and unhealthy places, are the 
following :— 
1. E. robusta, or “ the Swamp Mahogany,” a fine tree rising to 
100 feet or more with a proportionate girth. This tree has larger 
fruit and flowers than most of the Eastern species, and the leaves 
are broad and long, especially when growing in wet or damp localities. 
In the early days of the colony, this was one of the first Eucalypts. 
which attracted the notice of botanical collectors, and though the 
larger trees have long since succumbed to the woodmen, fair 
specimens of it may be seen in the neighbourhood of Sydney and 
Parramatta, and here and there on the low lands near the Hawkes- 
bury. Independently of its useful properties, it is one of our finest 
Hucalypts, and its foliage may be regarded as umbrageous. 
2. H. largiflorens, “the Bastard Box,” or ““Swamp Gum.” It 
occurs for the most part in marshy places, has a profusion of flowers 
in the season, and whilst the younger trees resemble the common 
Box, E. hemiphloia, the large oues approach some forms of the 
Grey Gum, EL. tereticornis but they may easily be distinguished by 
the enclosed valves of the fruit and the very divergent veins of the 
leaves. Baron F. von Mueller connects this tree with the Stunted 
Box of the interior. The typical species attains considerable size,, 
and the wood when dry is hard and tough. 
3. EH. longifolia, known as ‘‘ Woolly Butt,’ which has the 
flowers usually in threes, and the fruits larger than most of those 
belonging to the Eastern species. The bark is persistent (although 
sometimes it falls off from old trees,) and the leaves when growing 
near water are frequently a foot in length and contain a great deal 
of volatile oil. 
4. KE. saligna, “ Flooded or Blue Gum,” one of the Gums first: 
described from Port Jackson (1795.) This is a smooth barked and 
ine tree, occurring generally in gullies or the mountains, or on the
