Caption: Light micrograph of secretory glands (or trichomes) on a wormwood, Artemisia absinthium. A number of variations of structure exist in this type of trichome but generally a number of specialised cells form a small cushion over which a membrane develops. Each cell produces & secretes a cocktail of oils which accumulate beneath the membrane causing it to swell. A bitter dark green oil can be extracted from the leaves and tops of wormwood. Formerly used in medicine as a tonic and vermifuge, it is still used to flavour vermouth and absinthe. Plants usually secrete extrafloral substances as a defence against bacteria, fungi or predators. Magnification: x200 at 35mm size.
