" A manna is said to drop also from a species of Eucalyptus occurring near Cape 
Leeuwin." (" Conditions of forests and timber trade of W.A.," 1883, p. 22.) This is 
a quotation by Mueller in " Eucalyptographia " under E. viminalis, but the actual 
reference is " Manna Gum is found on portions of the coast west of Bunbury. It is 
little inferior (if at all) to the manna of commerce, and is used as food and for other 
purposes." 
I have made local inquiries in regard to this manna, but unsuccessfully so far. 

g. E. punctata DC. 
' The foliage produces occasionally melitose-manna." (" Eucalyptographia. ") 
In the Sydney district I have seen the bitten edges of leaves of this species encrusted 
with manna, an observation, I believe, originally made by the Rev. Dr. Woolls. Mr. 
D. W. C. Shiress has found it on the fruits and flowers of var. grandiflom near the first 
section, Spit-Manly tram. 
Mr. J. J. Fletcher showed a rather larger quantity of manna on E. punctata DC. 
than is usually seen on the leaves, and he observed the avidity with which honey-caters 
of two genera, viz., Acanthorrhynchus tenuirostris and a species of Ptilotis, availed 
themselves of this addition to their ordinary food-supply (Proc. Linn. Soc. N.S.W., 
xxviii, 686, 1903). 
See also H. G. Smith " On the saccharine and astringent exudations of the Grey 
Gum, Eucalyptus punctata DC., and on a product allied to Aromadendrin " (Proc. Roy. 
Soc. N.S.W., xxxi, 177 (1897) ). An investigation of the sugary exudation, and the 
isolation from it of Raffinose. The manna was found on the bark at Belmore, near 
Sydney. Its origin does not appear to be clear. ' When exuding it must have been 
liquid as it had run down the tree." The material obtained was more or less mixed 
with bark and debris, caused by boring beetles. Mr. Smith's analysis is ample, but we 
require further investigation in regard to the physiological aspect, i.e., the way in which 
sugar in such large quantities has been manufactured, and has exuded from the tissues 
of the plant. 
Dr. Greig Smith recorded the occurrence of a race of Bact. Eucalypti Greig Smith 
in a sample of manna of E. punctata (Proc. Linn. Soc. N.S.W., xxviii, 831, 1903).

X. Landerer, " On the varieties of manna not produced by the Ash " (Pharm. 
Journ., xiii, 411), mentions " Manna Australis produced by Eucalyptus resinifera."
