Introduction. Campanula alpina is a perennial herbaceous bellflower grown in the Eastern Alps, Carpathians, and Balkans. Fruit in Campanula species opens by the hippocrepiform slits in the fruit wall, which are formed by axicorns, elongated structures inside the ovary composed of lignified parenchyma cells. Our objectives were to reveal the fruit structure and dehiscence mode in C. alpina and compare it with C. latifolia, a type species of the genus Campanula. Materials and methods. Flowers and
