Lavender leaf showing oil glands (Lavandula dentata)

Ref: 80200166

Coloured scanning electron micrograph (SEM) of a section of French lavender (Lavandula dentata) leaf, showing the tooth-like structures (trichomes, spikes) that give the plant its Latin name dentata, meaning toothed. A number of oil glands (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.
