1 7. Acacia Osswaldi, F. v. Mueller . 
In the Mallee scrub, not uncommon, but always remaining a 
small tree. The plant is exquisitely adapted for tall hedges. It is 
often called the 11 umbrella tree,” as it gives a capital shade. The 
heart-wood is dark, hard, heavy, and close-grained. It would be 
useful for cabinetwork, turnery, etc. 
18. Acacia penninervis, Sieber. 
Scattered through the eastern half of the colony, over ridges 
and ranges gregarious on some of the sub-alpine declivities and 
plateaux. A usually small tree. (F. Mueller.) The bark yielded 
of tannic acid 17 ‘9 per cent., and of gallic acid 3*8 per cent. The 
bark of this species was chosen by Baron von Mueller to demon- 
strate the fact that many of the species of this great genus are 
calculated to afford, in their bark, a large supply of material 
adapted for packing papers. ( Official Record , Exhibition , 1866, 
page 246.) 
19. Acacia pravissima, F. v. Mueller. 
Upper Gippsland and Buffalo Ranges. A tall shrub or small tree. 
20 . Acacia pycnantha, Bent ham . 
GOLDEN WATTLE. 
Frequent throughout the greater part of the colony, in open 
forest country or scrub, as well as on the sea-coast. This is one of 
the species yielding superior tanners’ bark and wattle gum. The 
specific gravity of the wood has been given by Mr. Osborne as 
0*830 ; weight of a cubic foot of dried wood about 51 lbs. 
21. Acacia retinodes, SchlechtendaL 
On grassy ridges and open valleys throughout the greater part 
of the colony. A moderate-sized, ever-flowering tree ; yields good 
tan bark; also gum. The wood is prettily grained, tough, and 
durable. 
22 . Acacia rigens, A. Cunningham . 
Desert country along the Murray and Wimmera. A tall shrub 
or small tree. Wood hard and tough, and possessed of a very 
agreeable perfume.
