We present evidence that the capitate glandular trichomes of Blanzyopteris praedentata, a lianescent seed fern from the Upper Carboniferous of France, possessed a specialized, touch-sensitive mechanism that triggered the opening of the secretory cell by contact. The trichomes are interpreted as functionally similar to those of some modern flowering plants, which release a sticky exudate when touched and ruptured that functions to disable plant-feeding arthropods.
Keywords: defence mechanism, glandular trichome, herbivory, seed fern, Upper Carboniferous.
