What does «Agalla o Cecidia» mean in Spanish?
- An excrescence or deformation that appears in the tissues of a plant, caused by the action of plant parasites (Phytocecidias) or animal parasites (Zoocecidias) such as fungi, bacteria, silt, mulch and numerous insects. The study of galls or cecidias is called cecidology. They appear as warts, tubercles or tumors on plant structures or as fleshy or woody formations in which the host plant and parasites intermingle.
