(a) Normal Form. 
Following is the original description :— 
In the woods we passed through this day we found a curious willow-like acacia, with the leaves 
slightly covered with bloom, and sprinkled on the under side with numerous reddish minute drops of 
resin. (Mitchell.) 
Then we have Lindley’s foot-note :—“ This is allied in some respects to A. vernicijiua and exudans, 
but is a very distinct and well-marked species. A. salicina (Lindl. MSS.), glaucescens, ramulis angulatis, 
phyllodiis divaricatis lineari et oblongo-lanceolatis utrinque angustatis obtusissimis uninerviis venulis 
pinnatis: ipso apice glandulosis subtus resinoso-punctatis, capitalis 3-5 racemosis phyllodiis triplo 
brevioribus.” (Mitchell, Three Exped., ii, 20 [1839].) 
The type was* collected 30th March, 1836, near Oxley and G. W. Evans’ 
marked tree on the Lachlan, New South Wales. 
. Botanical Name. — Acacia, already explained (see Part XV, p. 104); salicina, 
Latin salix, solids, a Willow, and hence “ willow-like,” hut this name is most 
applicable to the variety varians. 
Vernacular Name.—“ Umbrella Bush.” 
Aboriginal Names.—“ Muntharra,” Lake Eyre natives eat seed (W. 
Baldwin Spencer); “ Wirrha,” Cooper’s Creek, near Lake Eyre (A. W. Howitt); 
“ Kakooroo ” or “ Wurra ” (Max Koch). (“ Wurra ” and “ Wirrha ” are evidently 
the same word.) All the above in use in South Australia. 
Leaves.—This is one of the species whose leaves are used to burn for the 
ash which the aborigines mix with the Pituri, their masticatory. 
Flowers.—Of a bright yellow colour, in contradistinction to the paler, 
sparser flowers of var. varians. 
Fruit.—The pods are fleshy. The blacks eat the seed at Lake Eyre (W. 
Baldwin Spencer). 
Exudations.—“ We found a curious, willow-like Acacia, with the leaves 
slightly covered with bloom, and sprinkled on the underside with numerous reddish 
minute drops of resin ” (Mitchell). This species also exudes a soluble gum from 
the bark. The genus Acacia therefore produces both a gum and a resin. 
Size.—A tall shrub up to about 8 or 10 feet high, and very umbrageous. 
Habitat.—The range of the normal species, as given in the Flora 
Australiensis, is as follows :— 
North Australia. —Banks of creeks, Arnhem’s Land, F. Mueller; Curtis Island, Ilenne. 
Queensland. —Open forest lands on the Balonne, Mitchell; Suttor River, F. Mueller. 
New South Wales. — On the Lachlan, and thence to the Barrier Range, A. Cunningham, Mitchell, 
Victorian Expedition, die. ; Liverpool Plains, Leichhardt.
