The work containing the original description is so excessively rare (only a few 
pages of Part ii having been printed, and only a very few copies having been published) 
that it will be a public convenience to have it here. 
No. 184. Acacia Oswaldi F .M. in Linncea xxvi, 609. 
Shrubby ; branchlets hardly angular, glabrous or short-downy ; stipules obliterated ; phyllodia 
sub/akate or linear-lanceolate, rarely linear or oblong -lanceolate, closely, finely and almost equally many- 
nerved, cuspidate [italics as in original. J.H.M.] rigidulous-coriaceous, on very short petioles gland-bearing 
at the base; capitula small, 8-12 flowered, sessile, or on exceedingly short peduncles, solitary or frequently 
geminate ; bracteoles oblong- or ovate- or rhomboid-cuneate ; sepals narrow- or cuneate-linear, free, about 
half as long as the disconnected petals; j.ods usually spirally twisted and elongated, stiff-coriaceous, 
bivalved, inside continuous, gently or scarcely contracted between the seeds ; funicle almost obliterated ; 
seeds placed lengthwise, brown-black, shining, with large lateral areoles ; strophiole orange-coloured, cordate- 
or rounded-cymbiform, nearly half as long as the seeds and clasping its lower part unilaterally. 
In the desert on the Murray River; extending thence to the Murrumbidgee, the Lachlan River, 
the Darling River, Cooper's Creek, and St. Vincent's Gulf. 
A good-sized bush. Phyllodia glabrous or almost imperceptibly downy, pale-green, 1-3 inches long, 
1-4 seldom 6 lines broad, distinctly though finely streaked ; the cuspis oftener straight than bent, variable 
in length ; gland at the base of the phyllodium usually conspicuous, concave. Flower-heads very fragrant, 
only by the occasional want of phyllodia at the extremities of the branchlets short-racemose. Sepals acute, 
very slightly downy towards tho summit. Petals about f line long, glabrous or hardly perceptibly downy. 
Pods glabrous or very thinly velutinous, attaining a length of 8'inches, although usually more or less shorter, 
\-\ inch broad, sometimes irregularly twisted or by abbreviation simply cyclic. Seeds 3-4 lines long, 
moderately compressed. Strophiole 2-2J lines long and broad, from a short narrow appressed funicular 
base suddenly dilated, not conduplicate, bleaching in age, blunt or slightly acute at the apex. 
This species was referred doubtfully to A. elongata in the Linneea xxvi, 609. It was named many 
years ago in acknowledgment of contributions to the author's collection made by Mr. Ferd. Oswald, then 
a resident of Adelaide, now of Nordhausen (Prussia). Seemingly the same species was collected in 
Queensland towards Broad Sound. (Mueller in " Plants Indigenous to the Colony of Victoria," Vol ii, 
P- 27.)
