Ref: 80200156



Lavender leaf (Lavandula dentata). Coloured scanning electron micrograph (SEM) of a section of a French lavender leaf, showing the tooth-like structures (trichomes, small spikes) that give the plant its Latin name dentata, meaning toothed. A number of oil glands (small spheres) can also be seen. When the leaf is touched or damaged, the glands rupture and release the oil that gives lavender its distinctive fragrance.
