Caption: Lavender leaf. Coloured scanning electron micro- graph (SEM) of a section through the leaf of a lavender plant (Lavandula angustifolia). Numerous dense branched hairs (trichomes) cover the leaf's surface. These have both a protective function against pests and serve to reduce evaporation from the leaf. The rounded structure (pale brown, lower centre) is an oil gland, which produces the plant's aromatic oil. Below this is the sectioned leaf, with the impermeable cuticle uppermost, supported by epidermal cells. Lavender is a herb which grows wild in the Mediterranean region, but is farmed all over the world. Magnification: x380 at 6x7cm size. x590 at 4x5"
