12/5/79.
Can you kindly inform me, dear Mr Ramsay, whether more than one of the Cicads secretes the sap of Eucalyptus viminalis & perhaps other Eucalypts in the form of so called Manna, and what the accurate name of these insects is?
Regardfully
Ferd. von Mueller
Perhaps Mr McLeay1 may know.
Eucalyptus viminalis
