THE RED MAHOGANY (LUCALYPTUS RESINIFERA, Sm.) : 
Boranrcat Dusortprron.—The Red Mahogany is a very large and lofty 
tree, attaining to a height of from 60 to 100 and even as much as 150 feet, with 
a diameter of from 2 to 3, and 4 feet. 
Bark.—The bark is rough, fibrous, and of a dark or reddish colour. It is 
persistent on the trunk, but is more or less deciduous on the branches. 
Leaves.—The leaves are alternate or opposite, lanceolate, straight or 
curved, generally thick and very large, measuring from 4: to 6 or more inches in 
_ length. 
Flowers.—TVhe flowers are six or more in number on each peduncle or 
flower stalk. 
Fruit,—The fruit is a semi-ovate capsule and the seeds are ripe in June. 
Verwacunar axp Borantcar Names.—The Red Mahogany, so-called from 
the colour of its timber and the resemblance to the true mahogany, is also 
known as Forest Mahogany (from its habitat), Redgum, Red Ironbark (a 
misnomer) and Jemmy or Jimmy Low—the latter an English contraction of an 
aborigine word for this tree—tchimmeelo—and the one by which it is best 
known in Southern Queensland. It is also known as Leather-jacket (from the 
leathery texture of its bark), and as Hickory. The specific name resinifera was 
given to it by Sir J. E. Smith, the founder of the Linnean Society, from the 
large quantity of kino or gum which exudes from it. ; 
Disrripurion.—The Red Mahogany is found in the coastal districts of 
Queensland as far north as the Daintree River, but not very common. Some 
of the finest species are in the neighbourhood of Maroochy in the South part of 
the colony. It is also found in the coastal districts of New South Wales. 
Usr.—The Red Mahogany furnishes a very strong, durable, red timber. 
extensively used for large beams in buildings, rafters, rough carpentry, and 
also for house work. On account of its superior strength and durability it is 
used for piles for jetties and wharves, resisting for some time the attacks of the 
cobra. It is in great demand for fencing, and lasts for many years. In New 
South Wales fencing posts of this timber have been found to be sound after a 
period of 50 and 60 years. Another instance of its durability is given in the 
same colony. In building St. John’s Church at Parramatta in 1798, rafters of 
this timber were employed, which were found to be quite sound when the church 
was pulled down in 1852— after a period of 54 years. It is a suitable timber 
for paving blocks. The gum of this tree yields about 66 per cent. of kino 
tannin, and is valuable as‘a medicine in diarrhea. This gum or resin had the 
honour of first bringing into notice the celebrated medicinal kino. 
This tree is one that is largely planted in countries outside Australia, and 
has proved to be one of the best adapted for a tropical climate, although it has 
not so rapid a growth as other species of Kucalypts. In the north-west pro- 
vinces of India it has been found to grow at the rate of from 4 to 6 feet per 
annum. In Italy it has proved almost as hardy as the Mountain Ash, 
L, amygdalina, Labil., and the Manna Gum, 2. viminalis, Labil. 
THE SWAMP MAHOGANY (TRISTANIA SUAVEOLENS Sm.) 
Borantcan Descrrerioy.—The Swamp Mahogany is a moderate-sized 
tree, though often attaining large dimensions. Its height averages from 50 to 
80 or 100 feet, with a diameter from 24 to 50 inches. 
Bark.—The bark is persistent, somewhat fibrous and soft. 
Leaves.—The leaves are alternate, petiolate (having a leafstalk), ovate- 
lanceolate in shape, from 3 to 4: inches in length, and more or less downy. or 
hoary, as are also the young shoots.
