yellow, solitary or racemed, the racemes usually shorter than the leaves. Calyx of five clavate, ciliated 
segments. Corolla, with the petals, oblong, ciliated. Stamens numerous. Style about the length of the 
filaments. 
Hooker says this species " is one of the many novelties sent by Mr. 
Drummond from the Swan River Settlement " (Western Australia). If this be true, 
then it is singular that no one has since recorded it from that State, and there has 
been much collecting over Drummond's limited areas. Bentham is probably correct 
when he says " Chiefly in South Australia." Bentham, of course, had access to 
Hooker's type, and besides his remarkable knowledge of Australian plants, he was 
an eminent authority on the genus. 
(b) A. bombycina Bentham. This is described by him in Lindley and Paxton's 
" Flower Garden," ii, 101, figure 186 (1853). 
It is (B.F1. ii, 374) stated by Bentham himself to be synonymous with 
A. argyrophylla, and, like that species, was believed to have been " raised from seeds 
from Mr. Drummond ... a fine silky leaved New Holland shrub from Swan 
River." He had, however, unfortunately mislaid his flowering specimens, and the 
description was apparently drawn up from a figure which had been prepared from 
them. 
The phyllodes vary a good deal in regard to their shape, being bluntly 
lanceolate and 1 cm. wide, to obovate 3 cm. wide. In this form the silvery and 
golden down of the young foliage is most highly developed. 
4. Var. Spilleriana F.v.M. (herb.), A. Spilleriana J. E. Brown. 
This is figured in J. E. Brown's "Forest Flora of South Australia " (t. 31), 
and described by him in the following words : 
An evergreen shrub of from 7 to 10 feet in height. 
Branchlets glabrous. 
Phyllodid smooth, angular, ovate, obovate, sessile or almost so, obtuse at apex, and acuminate 
at base, coriaceous, scattered, alternate and opposite, J to 1 inch in length, and ^ to over 
1 inch in breadth, occasionally oblique, one-nerved, and with prominent irregular veins. 
Peduncle f to 1J inches long, slender and solitary as a rule. 
Flower heads globular, fragrant, golden-yellow in colour, jj inch in diameter, and containing 
from 20 to 30 or more flowers. 
Sepals connected. 
Petal* smooth and distinct. 
Pod 1 1 to 2 J inches long and \ an inch broad, coriaceous, stiff, generally linear, though some- 
times undulating. 
Seedi more than semi-lateral. 
Funicle short, white, longitudinal and once folded. 
Aril thin and clavate. 
The differences between A. brachybotrya and A. Spilleriana are stated by 
J. E. Brown to be as follows : 
The leaves (phyllodia) of A. brachtfbotrya and those of the form under review are much alike, 
although the latter are perhaps more ovate-shaped than those of the former : while again the pods of 
A. Spilleriana are double the breadth of A. brachybotrya. In (he latter .species the flower-stalk (peduncle) 
is described as being rather short, and more frequently than otherwise " two to five together on a very
