- Silver-leaved Acacia. 
Nat. Ord. Leguminosa#.—Po.yGAMIA PoLYANDRIA. 
Gen. Char. (Vide supra, Tas. 4306.) 
Acacta argyrophylla; ramis angulatis, foliis obovato-oblongis obtusis obscure 
penninerviis pulcherrime argenteo-sericeis hine margine medium versus 
uniglandulosis, capitulis multifloris solitariis v. racemosis, calycis laciniis 
clavatis corollisque ciliatis. 
This species is one of the many novelties sent by Mr. Drum- 
mond from the Swan River Settlement, and is no less beautiful 
in the foliage (phyllodia) than in its copious large heads of deep 
yellow flowers. The phyllodia are like the leaves of Podalyria 
sericea, everywhere clothed with a glossy silky cobweb, in the 
young leaves partaking of a yellow tint. Already our shrub is 
five feet high, very much branched, of graceful and compact 
growth, with phyllodia more like leaves than those of almost any 
other species. It flowers in April. 
Descr. A tall shrud, with numerous erecto-patent branches. The 
latter are angled, the young ones silky, yellow-green. Phyllodia 
from one inch and a half to two inches and a half or more long, 
obovato-oblong, very obtuse, pointless, and opening below into a 
very short footstalk, clothed on both sides with a compact, glossy, : 
silky, and silvery down, the younger leaves richly tinged with 
yellow ; the margin is a little thickened, and, about the middle 
of the upper edge, is a gland. Stipules obsolete. Heads of 
Jlowers rather large, globose, deep 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.
