(a–d) SEM micrographs showing the morphology of peltate trichomes on leaves of T. quinquecostatus. (a) The vertical section of peltate trichome, showing the subcuticular space. (b-c) show the cuticle rupture through which the essential oil released. (d) The senescent peltate trichome caving in to the epidermis entirely. (e) The semithin section stained by hematoxylin, showing the senescent peltate trichome.
