title: Carpology of the genus Tragopogon L. (Asteraceae)
abstract: 67 species of Tragopogon were investigated with regard to fruit anatomy. The outer achenes, especially the beak and the central part of the seed-containing body, provide the most valuable features (diameter and outlines of the body and the beak, and arrangement of the mechanical elements in the body parenchyma). Some specimens of widely distributed taxa (e.g. T. capitatus, T. dubius, T. pratensis, T. pseudomajor) show variation in the character set and require more investigation prior to further
