Accepted name: Aloysia citriodora
Deciduous shrub to 3 m or more tall. Shoots with angled edges. Leaves to about 10 cm long, mostly in 3s, lanceolate, long-pointed, entire or sometimes toothed, markedly lemon-scented when crushed. Flowers to about 5 mm long, numerous, in downy-branched clusters to about 15 cm long, white; summer. [Aloysia citriodora (Cav.) Ort., Lippia citriodora (Ort.) Humb., Bonpl. & Kunth.]
The lemon-scented oils so noticeable when the leaves are crushed are used in refreshing teas, and pot-pourri, also as an additive to French liqueurs.
