Leptospermum liversidgei, commonly known as lemon-scented tea-tree,[1] swamp may, olive teatree, or lemon teatree, is a shrub to 4 m found naturally growing in wet coastal heath in Eastern Australia. Leaves are 5–7 mm long, with a distinctive lemony aroma. The white or pink flowers are solitary, followed by a woody capsule.

The name "Leptospermum" is from the Greek "leptos sperma" which means "thin seed", and "liversidgei" is after Professor A. Liversidge.

Leptospermum liversidgei has two essential oil chemotypes:

  • The citral chemotype is used as a bushfood spice to flavour teas and food products. This citral chemotype is sometimes called "lemon teatree" when the dried leaves are used in tea, and as food flavouring. Small-scale production is from wild-harvesting.
  • The citronellal chemotype is cultivated as a mosquito repellent.

The shrub is also cultivated as a garden ornamental.

Leptospermum petersonii, is also called "lemon-scented teatree", and produces a similar lemony essential oil.
