172 AUSTRALIAN NATIVE PLANTS. 
Wales on the subject. Professor Liversidge had more material at 
his disposal than had previous observers ; moreover, his research 
is probably the most exhaustive that has ever been made on the 
subject. The paper (Proc. R.S., V.S.W., 1880, 123) scarcely 
bears abstracting. Professor Liversidge isolated a brown, liquid, 
acrid alkaloid, distinct from nicotine, which he calls piturtne. 
Interior of all the colonies except Tasmania and Victoria; in 
other words, from the Darling and Barcoo Rivers to Western 
Australia. 
52. Duboisia myoporoides, #.2r., (Syn. Notele@a ligustrina, Sieb.) ; 
N.O., Solanez (Scrophularinez in B.FI.); B.FI., iv., 474. 
Called ‘‘ Corkwood” and ‘‘ Elm” by the colonists, and ‘‘ Orungurabie” 
by the aboriginals of the Clarence River, New South Wales. ‘‘ Ngmoo” is 
another aboriginal name. 
The first important statement as to the narcotic effect of this 
plant I can find is recorded by the Rev. Dr. Woolls, from a 
correspondent of his. ‘It has an intoxicating property. The 
aborigines make holes in the trunk and put some fluid in them, 
which, when drunk on the following morning, produces stupor. 
Branches of this shrub are thrown into pools for the purpose of 
intoxicating the eels and bringing them to the surface. I have 
known an instance in which giddiness and nausea have arisen 
from remaining in a close room where branches of it have been 
placed.” The smell is faint and sickly, but with nothing like the 
intensity of D. Hopwoodit. 
Dr. Bancroft, of Brisbane, obtained an extract from the plant, 
which he found useful in ophthalmic surgery, and he introduced it 
to the medical world. 
The leaves owe their active properties to the presence in them 
of an alkaloid called dubozsine, which Ladenberg pronounces 
identical with hyoscamine, albeit there are minute differences 
between them. The method adopted by Mueller and Rummel to 
obtain the alkaloid, and a short account of the latest researches 
of Ladenberg in regard to its position, are given herewith. (See 
also Liversidge, Proc. R.S., V.S.W., 1880, 125.)
