' 3T Botanical Name. — Qasuarina , already explained (see Part XIII, p. 79) ; 
equisetlfolia, from Equisetum , marsh plants known in Britain as “Horse tails,” and 
folia , Latin, leaves, the branchlets of Casuarina reminding the first describer 
irresistibly of Eqnisetum. 
Vernacular Name, —I do not know any actually in use, but suggest 
“ Coast Slie-Oak ” as as good as any. 
Aboriginal Names. — Typical form. Dalgan is a name used in North 
Queensland (see N. Q. Ethnography, Bull. No. 2, Both) ; var. incana , “ Wunna- 
wunnarumpa ” is a name given by Queensland aborigines. Mr. George Watkins 
gives the spelling as “ Wunna-wunnarumpin ” as in use on Stradbroke Island. 
Bark. —The bark, according to Dr. Gibson, is an excellent astringent, and 
may be used with advantage in chronic diarrhoea and dysentery. It is not used 
medicinally by the natives of India. The Chinese in Bombay say that it is used as 
an astringent in China (Dymock). Doubtless the barks of the numerous other 
Australian species possess similar properties. See also Bharmacographia indica, 
p. 357. 
The bark was formerly used by South Sea Islanders to dye their cloth. 
KillO— Eor a brief examination of this kino, collected by the Horn Exploring 
Expedition, see “ Notes on some vegetable exudations.”* Kino in this genus is 
rare, and the reference to the gum (kino) of C. equisetfolia (Bharmacographia 
indica , 375) will be useful. 
Timber. —The following notes on the timber are quoted by Mueller;—• 
Splendid for fuel, giving great heat and leaving little ashes. The timber is tough, nicely marked. 
The tree will live in somewhat saline soil at the edge of the sea. Colonel Campbell-Walker estimates the 
yield of firewood from this tree as four times as great as the return from any tree of the forests of France. 
Known to have grown in ten years to a height of 80 feet, but then only with a comparatively slender stem 
(Blechynden). In India the wood is much used as fuel for railway locomotives ; the tree is there also 
extensively employed to reclaim sand-land of the coast, it succeeding in growth down to high-water mark, 
throwing often out decumbent branches, which develop roots, further to fix the sand and to throw up 
independent shoots (Dr. Bidie). It yields a lasting wood for piles of jetties, for posts and for under¬ 
ground work, and is much used for knees of boats and for tool handles (Wilcox); it is very heavy and 
singularly dark. The cost of raising Casuarinas in India has been from £4 to £10 per acre, and the 
return, after only eight years, £13 to £32. 
The following notes were published in my “Useful Plants of Australia ” 
(1889):— 
Wood coarse-grained and beautifully marked; it is used for fuel, and also for purposes where 
lightness and toughness are required (Hill). It is employed for log fencing, gates, and shingles. This 
tree will live in somewhat saline soil at the edge of the sea. In India it grows on pure sand, and is used 
as fuel for railway purposes. For this purpose plantations of it have been made near Madras. The ashes 
of this tree yield a quantity of alkali, which is used in some places to produce a coarse soap. The name
