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 demonstrate 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 Exhibition 
Report , 1866, page 246.) 
19. Acacia pravissima, F. v. Mueller. 
Upper Gippsland and Buffalo Ranges. A tall shrub or small

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
