摘要: Plants possess a variety of structures that harbor ant nests, and the morphology these domatia determines nature ant‐ plant mutualisms in given species. In this study, we report on differences anatomy between myrmecophytes Piper, which are regularly excavated by an obligate mutualist (Pheidole bicornis) nonmyrmecophytes consistently have solid stems. Stems species lacked outward evidence modification; however, striking anatomical were apparent hollow-stemmed before excavation remainder solid-stemmed studied. Prior to ants, stems characterized strongly heterogeneous piths large, central area had relatively large cells lacking intracellular crystals with periphery smaller containing numerous crystals. The domatium ants was restricted large-celled region. This is first absence ant-excavated portions myrmecophytes. Cauline became lined 3‐8 cell layers suberized wound tissue, may impact nutrient absorption Piper
