‘A ton of dry wood gave a maximum yield of t44lbs. of pearl-ash, or 
64lbs. of pure potash. (Mueller.) Height, 10 to 2oft.

106. Banksia serrata, Zinn. 7, (Syn. B. conchifera, Gertn.; B. 
mitis, Knight; B. denfata, Wendl. non Linn. f.; B. media, 
Hook. f., non R.Br.); N.O., Proteacez, B.FI., v., 556. 
“Honeysuckle.” Formerly called by the aboriginals of Cumberland 
and Camden (New South Wales) ‘‘ Wattung-urree.” 
This tree produces a handsome wood, but it is always bored 
by the larvae of coleopterous insects. It yields a purplish, 
mahogany-coloured wood, of remarkable colour, of coarse, open 
grain, and strong; forms a mottled figure in certain sections. 
Used for window frames. (Furors’ Reports, London International 
Exhibition, 1862.) It is available for boat and ship-building 
purposes, not being liable to split with nailing; it is used as 
knees, etc., and would make good furniture. (General Report, 
Sydney International Exhibition, 1879.) Specific gravity, .803 ; 
weight of cubic foot of dried wood, about solbs. (Mueller.) Like 
other Banksia woods it requires to be seasoned very carefully. 
The figure of Banksia timber is quite per se, and can rarely be 
mistaken. A slab of this wood in the Technological Museum, 
which has been seasoned over twenty-five years (having been 
exhibited at the London International Exhibition of 1862), has 
a weight which corresponds to 38lbs. 140z. per cubic foot. 
Tasmania, Victoria, New South Wales and Queensland. 
107. Barkleya syringifolia, 7.v.4/, N.O., Leguminose, B.FL., 
it., 275: 
Wood hard, close-grained, and of a blackish-grey colour. It 
might be suitable for tool handles. This tree is, however, of 
greater value to the horticulturist than to the timber merchant, its 
pleasant foliage and luxuriant yellow flowers rendering it a pretty 
object in gardens. Diameter, 12 to 15in.; height, 40 to 5oft. 
New South Wales and Queensland. :
