Acrocyum

Acrocyum refers to a type of gall, a plant growth caused by parasites, specifically one that is rounded and protrudes noticeably. The term is derived from the Greek words "akros" (meaning "outermost" or "extremity") and "kyos" (meaning "tumor" or "gall"). Acrocya are generally located on the leaves or stems of plants. While the term specifically describes the physical appearance of the gall, further details about the causative organism (e.g., an insect, mite, or fungus) are usually needed for precise identification and understanding of the specific interaction with the host plant. The size, shape, color, and surface texture of an acrocyum can vary significantly depending on the species responsible for its formation.
