Glandular hairs are spread over the aerial vegetative and reproductive organs of the Lamiaceae. They produce essential oils which apparently protect against herbivores and pathogens. From a functional viewpoint, owing to the mode and timing of secretion, the glandular hairs may be classified into two types: (a) short‐term glandular hairs, which start and end secretion rapidly, and which serve for the protection of young organs; and (b) long‐term glandular hairs, in which secretory materials accumulate gradually under an elevated cuticle, and which serve for the protection of mature organs. In the flower, protection against herbivores and attraction of pollinators are both apparently achieved by glandular hairs situated on various floral parts.
