Vernacular Names. —Its commonest name is “ Coach Wood,” so called 
because of the use of its timber in coach-building. It is also called “ Leather 
Jacket” because of its tough, fibrous, closely adherent bark. “Light Wood” is a 
common name for it (perhaps nearly as much in use as “ Coach Wood,” but an 
undesirable name as we have so many other light woods). It is so called because it 
is very light when properly seasoned, in fact about 40 lb. per cubic foot would he a 
fair average. 
Aboriginal Names. —“Boola” of the Illawarra blacks, and “Ngnaa rewing” 
of those of Brisbane Water, according to the late Sir William Macarthur. 
Synonym. — C. montanum , D. Don. was established on narrow-leaved 
specimens which do not otherwise differ from the common form. (B. LI. ii, 412). 
Flowers. —The flowers are white and not very conspicuous, hut as growth 
proceeds, the calyx very largely increases in size, takes on a crimson or purple 
colour, and becomes very conspicuous, forming what is known to most people as the 
“ flower.” 
Bark .—If the hark he wounded, it gives off a perfume; its smell is like that 
of Tonka beans or new mown hay, and is owing to the presence of a substance 
called “ Coumarin.” I have known a small slab of it to he useful for scenting 
linen-presses. I first drew attention to the presence of Coumarin in this hark, 
which is also referred to in Schimmel & Co.’s Bericht, April, 1890, p. 51, and 
Bharm. Journ. [3], xx, 856. 
Timber. —The one great value of this tree is for its timber, and it would be 
far more used than it is were it not for the frequently inaccessible gullies in which 
much of the best timber is found. It is tough and is used for tool handles and for 
boat and coach building. It possesses a faint but pleasant odour. It is said to be 
peculiarly well adapted for sounding boards, for musical instruments, for stethoscopes, 
and such purposes. Its uses in that direction have, however, been little more than 
tentative. 
Planks of Coach Wood, both wide and thick, may be procured from the 
larger timber yards in Sydney, so that enterprising people can have no difficulty in 
testing it for special requirements. Much of what supplies the Sydney market 
comes from Gosford. 
Its value as a coacli-builder’s timber is sufficiently great to be insisted upon. 
It is a useful timber to the coach-builder for placing in clean, dry situations. 
Under such circumstances it is equal to English ash. Its weakness is its liability 
to rot when left in damp or dirty places near the bottoms of carriages which are 
neglected and not kept clean. For very many years this timber has been in request
