Abstract:
The anatomical structure of the secretory hairs of eight species of Labiatae was studied and the main components of their secretory substances identified. Peltate and capitate hairs were found in all species, the latter consisting of three types, differing in structure and mode of secretion. The capitate hairs precede the peltate hairs in their development and secretory activity. In the capitate hairs the secreted material is extruded to the outside, while in the peltate hairs it remains in a subcuticular space. The eight species were divided into groups according to the structure of the volatile compounds they secrete. © 1985 Taylor and Francis Group, LLC.
