Grevillea robusta , A. Cunn. 
THE SILKY OAK. 
(Family PnoTEACEiE). 
In Part XX (vol. ii), p. 183, I drew attention to Leichhardt’s observation of 
the acrid secretion from the seed-vessels of a Grevillea in the Northern Territory. 
l)r. E. Mjoberg, the leader of the Swedish Scientific Expedition of 1910-11 
to north-west Australia, informed me that the sap of two species of Grevillea is 
used by the natives to scarify their bodies, forming the scars they deem to be 
ornamental. 
Following is an extract from a letter from Mr. Fellows, Curator of the Public 
Gardens, Albury, N.S.W.— 
I have a man working here, who, whenever he has to work much in the trees of Grevillea robusta , 
gets inflammation of the eyelids; have you met with a similar case, or can you account for it in any way 1 
No other tree causes him this inconvenience. I have asked our doctors about it, but none can account for 
it. By working in the trees I mean in the top of the tree, lopping or thinning out branches of the older 
trees. The sap is the trouble. We have some of these trees in the streets in this town ; the trees make 
good growth here. 
I have not heard of Grevillea robusla in this connection before. It is far 
better known as a planted tree (both in Australia and out of it) than in its native 
forests, and I would ask correspondents whether they have heard of its acridity. 
I would invite attention to what I have said in regard to Irritant Woods in 
Part xlix, p. 174 of the present work.

Cedrela australis , F.v.M. 
THE RED CEDAR. 
(Family Meliace^e.) 
Habitat. —See vols. i, p. 59; ii, p. 189; iv, p. 160. 
District Forester Swain, of Narrabri, says :—“ I have found Red Cedar 
growing in the Parish of Yant, County Hawes. I am wondering whether this is not 
one of the most western localities in which it is known to grow.” This is just 
north of the Upper Manning River.
