Eucalyptus dumosa

Australia (New South Wales, Port Philip District, Wimmera): sweet exudation from leaves made into ‘liquor.’ (Victoria, South Australia; New South Wales): yields a ‘manna’ called lerp or larp, the nidus of an insect (i.e. Psylla Eucalypti), with the following chemical composition: Water = 14%. A thread-like substance = 33%. Sugar = 53%. The threads swell slightly when the sugar is disolved in water. Thus freed from sugar, the threads consist of Lerp-amylum C6H10O5—–44.4C and 6.24H. This, on digestion with dilute sulphuric acid, etc. [sic], forms a crystallizable carbohydrate which agrees in its properties with dextrin. (South Australia): bark and root powdered and eaten separately or mixed with other plants. (Unspecified locale): root bark stripped off and eaten.
