The forms which he arranges under A. longifolia as varieties are : 
1. A. Sophorce R.Br. 
2. -4. phkbophyUa (A sophorce var. montana F.v.M.). 
3. A. alpina F.v.M. 
4. A.floribunda Willd. 
5. ^4. mucronata Willd. 
6. A linearis Sims. 
He concludes as follows : 
It thus appears, as far as the material available on this occasion permits us to ascertain, that 
A. longifolia, in a wide range over climatically and geologically very different localities, assumes forms as 
discrepant as those of Dodonaea viscosa and several other highly variable and extensively distributed species. 
A. glaucescens, Willd. Sp. Plant, iv, 1052, from New South Wales and Queensland, of which A. Cunninghami 
and probably also Wendland's A. homomalla form varieties, differs from A. longifolia in more or less falcate 
phyllodia, which are closely streaked by subtle secondary nerves and produce a basal not very conspicuous 
gland, in an usually five-toothed calyx and thus five-cleft corolla, in slightly compressed pods and deep- 
yellow strophioles. This plant may perhaps exist amongst the subtropical plants of Eastern Gipps Land. 
The structure of the flowers of A. longifolia reminds of that of A. Riceana, a species in most other characters 
widely distinct 
Taking the forms he then looked upon as varieties in order, we have : 
1. Acacia Sophorce R.Br. in Hort. Kew. ed. ii, vol. v, 462 ; Loddig. Cabin, t. 1351 ; Benth. in Hook. 
Lond. Journ. of Bot. i, 372 ; J. Hook. Fl. Tasm. i, 110; Mimosa Sophorce Labill. Nov. Holl. Plant. Specim. 
t. 237. Restricted to the coast, where on sand-ridges it is abundant from the eastern extremity of the Great 
Australian Bight along the shores of South Australia, Victoria, Tasmania, New South Wales, and the southern 
part of Queensland. The phyllodia are rather shorter, comparatively broader, lanceolate-oblong, generally 
of thicker consistence, when well developed often only 2-3 inches long, and fully 1 inch broad, although 
not unfrequently also longer and narrower ; their veins form generally a more complete network ; the pods 
are frequently arched. 
[See Part LVI, p. 127.] 
2. Acacia phlebophytta (A. sophorce var. montana, F.M. in Proceed. Linn. Soc. iii, 138). In deep 
fissures of huge granite boulders at 3,000-4,000 feet elevation on the Buffalo Ranges. The phyllodia are 
thick-coriaceous, shining, oval-oblong or obovate, generally provided with a conspicuous stout petiole, 
copiously prominently and regularly net-veined and sometimes fully 2 inches broad ; the young shoots are 
somewhat viscid ; the pods are at least often if not always distinctly compressed and attain thus a width 
of nearly inch. But A. salicina exhibits still greater inconstancy in the breadth of its legumina. , 
[See B. Fl. ii, 398.] 
3. Acacia alpina F.M. Fragm. Phyt. Austr. iii, 129. On the alpine summits of Mount Useful and 
on the northern plateau of Mount Wellington. A shrub from a few to several feet high ; branchlets almost 
two-edged; phyllodia coriaceous, remarkably short, inaequilateral, cuneate- or roundish-obovate, oblique 
j-lj inch long, regularly and closely but finely net-veined; the short-pedunculate spikes are reduced to 
extreme shortness, J inch or often less long, and are thus producing often but few and never numerous 
flowers ; the bracteoles comparatively larger and less densely ciliated ; the pods arched. 
This is looked upon by Bentham as a distinct species in B.F1. ii, 397. 
4. Acacia floribunda Willd. Mueller's observations will be found at page 
of the present Part.
