In the present work I can only deal, with some degree of fulness, with 
Sophorce, typica, mucronata, and floribunda, which occur in New South Wales. In 
addition, I shall deal with two reputed varieties, prostrata and Bylongensis. 
In the present Part (LVI) we will deal with the normal form, and with 
varieties Sophorte, prostrata, and Bylongensis. In Part LVII varieties floribunda 
(A. floribunda Sieber) and mucronala will he taken. 
We will now deal with these varieties after dealing with typica, which 
includes the normal form or type of the species. 
(1.) typica Bentham, i.e., those plants which he includes under the normal 
form. I have already given the descriptions (chiefly by the older botanists) of the 
normal form which goes under typica. In the case of a species such as the present 
one, which has shown itself so adaptable as regards habitat, it is not surprising that 
it has shown itself variable, and we see this even in typica. 
A. spathulata Tausch., in Flora, 1836, 420, and A. intertexta Sieb., in DC. 
Prod, ii, 454 (" with broad phyllodia "), are both referred by Bentham to A. longifolia 
typica, but I have not seen them. The type of A. intertexta is PI. Exs. nov. holl. 
No. 453. 
Acacia obtusifolia A. Cunn. is described in the following words : 
" Foliis elongato-lanceolatis obtusis basi attenuatis binerviis venosis, spicis 
cylindraceis geminatis, legumine teretiusculo intus siccatopulposo. Blue Mountains. 
Allied to Acacia longifolia Willd." A. Cunn. in " Geographical Memoirs on New 
South Wales " (Barron Field), p. 345. 
Bentham refers this to A. longifolia typica (" with narrow phyllodia"), and 
I am in some doubt as to whether A, obtusifolia A. Cunn. may not be sufficiently 
distinct from A. longifolia to constitute a valid species. In December, at Mt. Wilson, 
it bore brown, nearly cylindrical pods. Funicle white, connected to the edge of the 
valve by a long prolongation of the arillus. 
It may be looked upon as the higher mountain form (as we go south it is 
found at diminishing elevations) of A. longifolia t and is. in flower usually at mid- 
summer, but sometimes later (normal longifolia usually in spring or late winter) ; its 
favourite situation is on ridges or dry slopes, not near watercourses. It forms a 
compact bush or small tree, far more dense in growth than typica. Its flowers also 
are usually of a paler yellow, and the venation is more reticulate. 
Mr. R. H. Cambage and I collected it on the Cox's River, the type locality, 
and some of the phyllodes are by no means narrow. 
It is common on exposed places Hassan's Walls, near Bowenfels, Mt. Wilson, 
at Mt. Victoria, Blackheath, Katoomba, Wentworth Falls, &c., and also on the 
Southern Railway line, e.g., at Hill Top (E. Cheel). In some of these localities 
the normal form is also found.
