142. Melaleuca ericifolia, Smith. 
THE SWAMP TEA-TREE. 
The so-called Tea-tree, though never used for preparing any 
beverage. It fills most of our brackish as well as freshwater 
swamps, and lines also innumerable watercourses. It is never a 
large tree, but, on the contrary, generally small, though it may 
be seen occasionally 50 to GO feet high. The wood is close- 
grained. In Tasmania it is used chiefly for turnery. It yielded 
on experiment — charcoal, about 28 per cent.; crude wood vinegar, 
4G per cent.; and tar, 7 per cent. The friable lamellar bark can 
be converted into an excellent blotting, perhaps also filtering 
paper ; 100 lbs. of leaves and smaller branches gave by distilla- 
tion 5 ozs. of an essential oil, resembling that of cajuput, from 
M. leucodendrou. The material in enormous quantities is obtain- 
able in most parts of the colony. A ton of dry wood yields 
about I 63 J, lbs. of crude potash, equal to 4J lbs. chemically pure 
potash. (F. v. Mueller.) 
143. Melaleuca parviflora, Lindley. 
(M. curvifolia , Schl.; M. Preissiana , Schauer.) 
Observed not only along the coast-tracks, particularly on sand, 
but also in the sub saline desert parts of Victoria. A small or 
middle-sized tree. Specific gravity of wood, 0'993 ; 100 lbs. 
of the leaves and branchhts of this species yielded about G ozs. 
of an essential oil, resembling that of cajuput very closely. 
Tlie material is largely obtainable in the Murray desert and also 
on the coast. ( Jurors' Report , 1861, page 40.) Weight of a 
cubic foot of dry wood, about G 2 lbs. 
144. Melaleuca squarrosa, Smith. 
Moist heaths and marshes, not rare. A tree developed in 
morassy forest glens to the height of 80 feet, the stem attaining 
then a diameter of 2 to 3 feet, usually, however, shrubby, the 
baik consisting of innumerable friable papyraceous layers. 
145. Monotoca elliptica, R. Brown . 
Natural Order — Epacridecc. ( Styphelia elliptical, 
8m .) 
In heathy coast tracks not rare. Never of large size. Wood 
useful for tools, particularly for planes and mallets; works well, and
