nre shortly petiolate, usually 2 or 3 together, white, with acute 



lobes longer than the tube. These are very essential differences, 



but for all that we cannot separate our plant specifically from 



A. albicans. The comparative length of the corolla-lobes is 



variable in the genus and apparently very variable in the species. 



A. Cunningham describes the flower of his type in the following 



words — "corollse laciniis tubo sequalibus," but figures the plant 



in the same work (Barron Field's ' New South Wales,' p. 335, t.2) 



with corolla-lobes acute, and decidedly longer than the tube. In 



the Herbarium specimens we find the length of the corolla-lobes 



very variable. In specimens from the Warrumbungle Ranges 



(W. Forsyth) the lobes are long and acute, as figured in Sweet's 



* Flora Australasica' (t.l6); in Berrima specimens (J. H. Maiden 



and J. L. Boorman) the lobes are shorter and rather obtuse, but 



both have the characteristic white tomentum of branched hairs. 



The same difference is in the length of the pedicels and in the 



densenessof the indumentum, but we cannot draw a line between 



the forms. 



With these modifications in the description of A. albicans it 



seems rather difficult to distinguish between this species and A. 



scabrella Benth., in sharp characters; but as far as our Herbarium 



material goes, A. scabrella is a much more slender plant with 



filiform pedicels and often almost filiform branches and more 



distant leaves, always easily separated from all forms of A. 



albicans.

A compact, bushy shrub, about 3 feet high, somewhat of the 

 habit of Westriiigia rosmarinifolia, covered all over with white 

 hairs, long and dense on the young shoots, on the calyces and 

 on the under side of the leaves, short and scanty on the upper 

 side of the leaves and on the old branches. Leaves very shortly 

 petiolate or almost sessile, ovate-lanceolate, with occasionally a 

 slightly cordate base, 3 to 5 lines long, the margins recurved or
