+Backhousia citriodora]]
-"The common name reflects the strong lemon smell of the crushed leaves. "Lemon scented myrtle" was the primary common name until the shortened trade name, "lemon myrtle", was created by the native foods industry to market the leaf for culinary use. Lemon myrtle is now the more common name for the plant and its products... B.citriodora has two essential oil chemotypes: The citral chemotype is more prevalent and is cultivated in Australia for flavouring and essential oil. Citral as an isolate in steam distilled lemon myrtle oil is typically 90–98%, and oil yield 1–3% from fresh leaf. It is the highest natural source of citral. The citronellal chemotype is uncommon, and can be used as an insect repellent." [[http://en.wikipedia.org/wiki/Backhousia_citriodora]]

-"Leaf from the citral chemical variety of lemon myrtle, Backhousia citriodora, was examined for volatile constituents by GC and GC/MS analysis of both steam volatile oils and solvent extracts. Identified constituents present at more than 0.1 per cent on average in the oil were found to be myrcene (0.1-0.7%), 6-methyl-5-hepten-2-one (0.1-2.5%), linalool (0.3-1.0%), citronellal (0.1-0.9%), iso-neral (0.6-2.7), iso-geranial (1.0-4.2%), neral (32.0-40.9%) and geranial (46.1-60.7%)... Comparison of chemical and physical data with those of other citral-rich commercial oils showed that B. citriodora was richer in citral than both lemongrass (Cymhopogon flexuosus and C. citratus) and Litsea cubeba." \\
